As innovators in the water and wastewater industries, Metropolitan has the knowledge, experience and capabilities of developing new technologies to create reliable products within the Municipal, Commercial and Residential sectors of the industries.

Metropolitan introduces four products recently added to our Ion® products line, Ion+® Ion® Endeavor , the Ion® ConverterIon® Gateway and an update to the Level Management System, the LMS II. As 2014 progresses, Metropolitan hopes to adhere to its promise of Rising to the Next Level, releasing more innovative products and maintaining its vision of being a single source for quality pumps, control systems and ancillary equipment serving many water and wastewater industries.


Metropolitan is proud to introduce the world’s first digital, piggyback sensor sump and sewage pump level control sensor, the Ion+®. This unique control sensor with integrated alarms works like a standard Ion® digital level control switch, while providing alarm notification through an audible buzzer, LED indicators, and dry alarm contact.

The alarm notifications include pump fault, system fault, and high-level alarm. The dry contact output of the Ion+® allows the device to be connected to external alarm notification systems such as our Ion® Gateway or MetroMail web-based remote monitoring systems. The Ion® digital level control technology provides superior performance and reliability when compared to industry standard mechanical pump switches.

With easy detection in the case of high water, this all in one digital sensor provides three colored lights located on the switch to indicate power, high water and many other functions.

This first of its kind solid state sensing technology has no moving parts and starts and stops pump through the piggy back and pump power cord. The multipoint sealing mechanism supersedes single surface seals with no contact points with an inverter rating for use with most battery backup systems.

The Ion+® is easy to install and can be used with a standard Ion|StormPro® pump.


 Ion® Endeavor

Designed specifically with the capability of operating two plug-in, single phase pumps simultaneously, Metropolitan recently developed the Ion® Endeavor, a Duplexing Plug-In Pump Controller. The unit will attract users and designers of dual-pump systems for sewage, sump, bilge, effluent, condensation and similar drainage applications.

This type of pump controller is ideal for many types of facilities, ranging from upscale residences to mid-size commercial buildings such as schools, bank-branches, university buildings and other applications which require simple straight forward control of two plug-in drainage pumps.

The Ion® Endeavor controller is perfectly matched with the Ion|StormPro® pump line, which includes pumps capable of flow-rates up to 150-GPM, while operating through the Ion® Endeavor.

Truly revolutionary in the plug-in pumping marketplace, this is no ordinary pump controller.  The Ion® Endeavor comes complete with a user-friendly LCD display screen, which allows the user to manage the operational aspects of the pump system, without accessing the wet-well. The wet-well level set-point controls the lead pump on level and can be adjusted from 2” to 72” in 0.5” increments.

The Ion® Endeavor automatically senses all critical operating information, including the ‘real-time’ water level, level-sensor functionality, pump operation or failures, operating time and the operating amps of the pumps.

Using Metropolitan’s Ion® Digital Level Sensors, the Ion® Endeavor has the ability to sense the water level, while the sensors remain fixed.

The display screen, combined with the LED status indicating lights, audible alarm and cutting-edge connectivity capabilities provides the user with unparalleled monitoring capabilities. The optional Ethernet module provides a web page showing system status and e-mail/text alarm notification The unit can be integrated with various types of external communication-devices such as Metropolitan’s MetroMail or Ion® Gateway web-based remote monitoring systems.

Ion® Converter

Metropolitan introduces a new way to continue using your original level control system without having to rely on the unreliable mechanical style floats.

Introducing the Ion® Converter, using the digital level information received from the revolutionary Ion® Digital Level Sensors, will now produce dry contact outputs that mimic operation typical of level switches. By operating the Ion® Converter and the Ion® digital level sensors the significant problems caused by using unreliable mechanical style floats are now eliminated.

Simply “make the switch” to the revolutionary Ion® Digital Level Sensors without having to replace the original control panel.

Ion® Gateway

To further expand both the capability and diversity of the Ion® product line, Metropolitan Industries is proud to announce the release of the Ion® Gateway, the company’s newly developed wireless sensor network.

The Ion® Gateway gives customers the ability to monitor incidents such as power loss, temperature, high water and more.  Using both the cellular gateway link and wireless sensors, the Ion® Gateway sends alarm notification direct to your e-mail address or SMS text account.

Customers can now remotely monitor various aspects of their home with a low-cost solution. The Ion® Gateway provides customers with advantages other monitoring systems simply cannot provide, specifically the ease of installation, price and its many monitoring capabilities.

Once the information has been received by the gateway it is instantly sent to the server. This technology allows the server to respond immediately whether it be a customer’s basement flooding or an intrusion within the customer’s home.

Metropolitan’s Ion Genesis® smart sensing controller gives users control of all vital pumping options.

The development of our Ion™ Digital Level Control float switch opened the door for the development of new products within the Ion product line including our user-programmable smart sensing controller, the Ion Genesis®.

To put in the most simplistic terms possible, the Ion Genesis® is the most complete pump controller on the market, providing the most features and safeguards against the devastation of flooding.

The Ion Genesis® comes complete with dual Ion™ Digital Level Control float switches which continuously diagnose and report real-time critical pumping information to the controller.  The controller itself gives users control of all vital aspects of pumping and efficiently cycles pumps to minimize pump turn-on cycles, ultimately adding life to the pump itself.

Metropolitan Salesperson James Spurney said everything starts with Ion™ Digital Level Control float switches, which are used in place of standard float switches.  These sensors are the most reliable on the market and incorporate no moving parts, which is associated with 98% of mechanical switch failures.

Basic features include a high water alarm and easy installation, but Spurney contends the Ion Genesis’® advanced features of protecting against floods are what distinguishes itself from similar products on the market.

“For starters, you have the redundancy of not just two pumps, but two of the most reliable float switches available,” said Spurney.  “Even if one of the float switches were to fail, a high water alarm will notify the user and will also keep both pumps operating.  This feature is not available anywhere else and will ultimately give users the time to replace a failed switch and still prevent flooding.”

Another unique feature of the Ion Genesis® is the ability for users to manually adjust the pumping level.  The level can be adjusted from 2” to 24” in 0.5” increments using the controller without entering the pit.  Spurney said this not only gives the product versatility, but can also extend the life of pumps as well.

“The ability to adjust the level differential is only available on the Ion Genesis®” said Spurney.  “Users can also set the level to produce the longest cycle time which is ultimately going to extend the overall life of the pump.”

Installation of the Ion Genesis® involves no hard-wiring or complex programming and can be used in small or large volume sump pits.

The combination of versatility, value and multiple fail safes make the Ion Genesis® the premier product in flood control.

“A pump alternator that is capable of testing the primary switch, the backup switch and has a high water alarm that can still run the pumps if switch failure occurs is a one of a kind piece of equipment,” said Spurney.  “In addition, the flexible nature of Ion™ Digital Level Control switches and the ability to adjust the pumping level ensures this product can be used in nearly any residential application.  Simply put, this is the best pump alternator available.”

According to the National Flood Insurance Program, floods are the most common natural disaster in the United States. Flash floods can occur in all 50 states and everyone lives in a Federal Emergency Management Agency (FEMA) identified “flood zone”- it’s just a question of whether you live in a low, moderate, or high risk area.

Based on NFIP data, floods have caused nearly $2.7 billion in U.S. losses over the past 10 years (2001-2010) and anyone can be financially vulnerable to floods: People outside of high-risk areas file over 20% of NFIP claims and receive one-third of disaster assistance for flooding.

While flooding may be overlooked in comparison to other natural disasters, the destructive nature of such an event is catastrophic. To minimize the risk of flooding, it is of the upmost importance to have dependable, high-quality equipment protecting your property and other valuable assets.

Metropolitan Industries’ Ion Product Line is designed to do just that. Our top of the line products incorporate the latest technologies designed to minimize the risk of flooding and have become the industry leaders in flood prevention.

As we move forward, we’re excited to announce the addition of new, innovative products to be added to our Ion Family. Each of these products has been developed with one constant goal: Incorporating new technologies to enhance the overall effectiveness of the product.

The Ion Family started over two years ago when Metropolitan Industries President John Kochan Jr. conceived the idea of developing the most reliable sump pump float switch. Since the development and release of the product, Ion™ Digital Level Control, the Ion Family has grown into the most dependable line of products in the flood control industry.

Ion™ Digital Level Control

When Metropolitan Industries launched their patented Ion™ Digital Level Control over two years ago, the entire dynamic of pump switch operation changed. Replacing traditional mechanical float switches and providing advantages over alternative types of pump switches, Ion™ Digital Level Control gives customers the reliability, operation and extended switch life no other product can provide.

“Generally speaking, the primary reason a sump pump will fail to evacuate the water is not because of the pump itself, but because of the float switch,” says Metropolitan Salesperson Brian Drafke. “Mechanical switches, which incorporate moving parts, will experience a great deal of wear and tear over time and are susceptible to failure.”

Switch failure, of course, leads to pump failure which can produce flooding in residential, commercial and industrial locations.

Ion™ Digital Level Control incorporates no moving parts, which is associated with 98% of mechanical switch failures. You’ll never have to worry about flooding during high periods of rain due to the design that handles high inrush pump loads and protects the electrical contacts.

Tested over two million cycles, Ion™ Digital Level Control adds life to your pump and provides a safeguard against switch failure due to its overall design.

In addition to its first of a kind solid-state sensing technology, it is leak resistant and extremely durable due to its proprietary enclosure, while multiple stainless steel screws supply optimized pressure to ensure superior sealing properties and durability.

What Ion™ Digital Level Control also provides is a diversity and quality customers never before have experienced.

• Comparison to the mechanical float switch: “With mechanical float switches, you’re limited in how many suitable applications they fit,” says Drake. “In small sump pits, these switches can be problematic and may not be usable. With Ion™ Digital Level Control, the switch can be placed in any size pit.”

• Comparison to the vertical float switch: “Vertical level float switches are limited in regards to level differential and where the unit can be placed in a sump pit,” says Drafke. “Ion™ Digital Level Control gives users the flexibility to place the switch anywhere and has standard differential heights of 6 inches for standard sump applications and 10 inches for sewage applications.”

• Comparison to the traditional pressure switch: “Without a doubt, the primary advantage of choosing Ion™ Digital Level Control over traditional pressure switches is the fact it comes without any moving parts,” says Drafke. “Not only does that eliminate one of the largest causes of switch failure, it simply gives the customer a higher quality product and adds life to the pump itself.”

Simply put, Ion™ Digital Level Control provides versatility and advantages over alternative pump switches the competition simply cannot match.

Metropolitan is committed to bringing the highest quality of products to the industry. The beginning was the development of Ion™ Digital Level Control and since then, our product line has grown even stronger.

To further expose our Ion|StormPro® product line, we officially introduced our Ion|StormPro® display trailer at the Illinois-PHCC show in late March of this year.  Complete with a water display, pumps and control equipment, the display trailer can best be described as a “trade show on wheels” with features that allow customers to learn about the full Ion|StormPro® product line firsthand.

Metropolitan’s Ion|StormPro display trailer features a water display, pumps and control equipment giving visitors a unique way to learn about the product line.

Since its premier appearance at the Illinois-PHCC show, Metropolitan has a conducted a number of counter days at plumbing supply houses featuring the trailer.  Participating in such counter days assists both customers and suppliers in learning more about the product line and new products soon to be released.

“Thus far, reception toward our display trailer has been very positive at counter days,” says Metropolitan Salesperson James Spurney.  “It’s a different, but unique and effective way for customers to learn about the product line from those who know it best.”

Spurney says that while visitors of supply houses are often left impressed, those employed at supply houses also benefit from trailer exposure.

Late last week, Metropolitan held a counter day at the Kankakee, IL branch of Connor Co.  Branch Manager Lonnie Surprenant found Metropolitan’s participation in the counter day both rewarding to visitors and his staff.

“The trailer itself is very impressive and the set-up is great because people are able to learn about the products face to face with Metropolitan employees,” says Surprenant.  “It also brings a lot to the table for us at Connor because we too can learn from the Metropolitan sales staff.”

In addition to the Ion|StormPro® trailer, the Budd Road Boyz Racing Team dragster was also present for this counter day.

“At the end of the day it’s all about the quality of our products and customer service,” says Spurney.  “With the display trailer, we can demonstrate both and hopefully educate customers and supply house personnel on Ion|StormPro® products.”

The Ion® Digital Level Controller that contains no moving parts that fail 98% of the time.

Mechanical pump switch’s days are numbered thanks to a new product called the Ion® Digital Level Control launched by Romeoville, Ill.,-based Metropolitan Industries that replaces mechanical switch operation with intelligent microprocessor technology.

Under development for several years, the patent-pending Ion® Digital Level Controller eliminates moving parts, which are the detriment of most mechanical switches and replaces it with solid-state sensing technology resulting in over 1.5 million cycles which is approximately triple the life of a mechanical switch.

“The problem was never the pump because they are generally built to last. The problem has always been the switch responsible for the critical task of turning the pump on and off,” says John Kochan, Jr., Metropolitan Industries President who developed the idea for the new product by utilizing solid state components and applying them to switch technology.

While mechanical switches are useful and function properly over a period of time, they are always subject to failure. “Mechanical switches use moving parts and wear and tear in a sump pit environment will always break those components down over time,” says Kochan, Jr.

Switch failures translate into non-running pumps, which can result in flooded commercial, industrial and residential locations.

With the demand for reliable switches evident with recent recalls put forth by some of the largest pump manufacturers during the last decade, Metropolitan began work over a period of three years to develop a product that can outperform mechanical switches in longevity and dependability.

How it works

The Ion® Digital Level Controller is a technologically advanced device that senses water level/pressure through the use of a proprietary sensor and microprocessor driven digital control. The microprocessor within the digital float sensor samples analog data from proprietary sensor, which electro-mechanically converts the water pressure to an electrical resistance. Because water pressure is directly proportional to the water height, the electrical resistance of the proprietary sensor is also proportional to the water height. The resistance of the proprietary sensor is measured by means of a resistive bridge network before passing into the microprocessors analog to digital converter.

Digital Level Controller

Metropolitan Industries Presdient John Kochan, Jr., holds the Ion® Digital Level Controller that has been tested over 1.5 million cycles and counting.

Traditionally, sump and sewage pumps often have been started by means of a mechanical switch. The mechanical switch design often uses a set of electrical contacts which close under a given water height scenario, thereby activating the sump pump. Due to the alternating nature of the electrical voltage source from the utility, large voltage differentials could possibly be present across the mechanical switch contacts prior to turning on a pump. When a pump is suddenly turned on under these conditions, large transient current surges could be expected as the motor begins to rotate. These transient surges often cause heating of the electrical contacts which, over time, effectively reduce the lifetime of the switch. This condition is further amplified when a mechanical switch attempts to open and turn off the pump.

When a mechanical switch suddenly opens an inductive motor load, the time rate of change of the current flow can be very large. This value, multiplied by the motors internal inductance, induces a large voltage transient across the mechanical switch contacts. This transient often causes arcing of the contacts which, over time, can cause the switch to wear and ultimately fail. It is well known in the sump pump industry that the cause of most pumping failures occurs when the pumps switch fails.

The embodiments of the ION Switch effectively eliminate the problem of switching transients and contact arcing by incorporating both a solid state switching device in parallel with an electrical relay. When a pump is called for, the turn on cycle begins by enabling the solid state device, or triac. The nature of the triac in our design is to switch on a load under low voltage conditions. By starting the pump motor from a low voltage potential, both radiated and conducted electrical noise have been dramatically reduced.

The Ion Digital Level Control is universal and can be used in almost any pumping application dependent of level control as well as effluent sump and sewage. To customize operation, the Ion® Digital Level Control has standard differential heights of 6 inches for standard sump applications and 10 inches for sewage applications and is inverter rated for use with most battery back up systems. The Ion® can be programmed for custom applications as well.

“We feel the Ion® Digital Level Controller will transform the plumbing industry much the way battery back up systems did in the 1980s because we figured the way to eliminate the moving parts associated  with most switch failures,” says Kochan, Jr.

“As wholesalers and plumbers realize there is a product available that can eliminate the problems associated with mechanical switches, it will only be a matter of time until mechanical switches are replaced entirely,” he added.
