Flow Products has a broad family of products to service this market. LMI chemical pumps feed a variety of chemicals to treat water including polymers, sodium hypochlorite, sodium fluoride, soda ash, sodium hydroxide, alum and sodium hexametaphosphate. Seametrics flow monitoring equipment include insertion paddlewheel flowmeters, turbine meters, insertion mag meters and instrumentation to show local or remote flow indication, pulse and 4-20ma signals out to interface with telemetry or PLCs as well as recorders or data loggers.

Microtel provides telephone dialers for out of compliance conditions. Performance Meters is a complete line of positive displacement water meters, turbine meters and fire hydrant meters. CIT Superior has a line of chlorine residual monitors and controllers. Sensorex provides pH and ORP sensors for any brand of controller with the proper preamp interface. Flux drum pumps assist in the transfer of chemistry from bulk tanks into smaller day tanks. Proquip manufactures process grade of mixers for food processing, pulp and paper or municipal water related applications. We round out this set of product lines for municipalities with Data Gator manhole flowmeters and data loggers, Delta Controls for flow and level transmitters and TAH for static mixers. The Myron L quality line of hand held pH, conductivity, ORP and resistivity meters covers a wide range of water treatment applications. Now Myron L has in line process monitoring instrumentation for the same functions covered by the hand helds. Blacoh pulsation dampeners are used to smooth out the flow of pulsing pumps so as not to damage piping and insure smooth flow delivery.

The industrial group of applications covers HVAC or boiler and cooling tower equipment. LMI chemical pumps are used for polymers, corrosion scale inhibitors, amines for corrosion control in return steam lines and biocides for cooling tower microbial control. Conductivity controllers from LMI cover both the bleed off of cooling towers and the blowdown of steam boilers. An alternate method of chemical introduction is to provide a Seametrics flowmeter on the makeup line and have a single or dual timer tied to the flowmeter actuate a chemical pump or bleed solenoid. Another application is pH monitoring and control in waste water. The LMI controller could activate an acid or caustic pump to assist in compliance of municipal levels for wastes. Sensorex pH probes are tied in with LMI controllers. Flux drum pumps transfer chemistry to day tanks.

Myron L makes a quality and low cost rinse tank controller for plating rinse based on conductivity. Their hand held conductivity and pH monitors can verify target levels are being met. TAH static mixers blend chemistry with process water and Proquip mixers stir process tanks with any required chemistry. Seametrics insertion meters are used to keep track of water used in various processes and can pace LMI pumps proportional to flow to add ingredients or do batching.

We have been finding new applications in this area for our products. In greenhouse, LMI pumps may be used to feed hydrogen peroxide to kill bacteria, polyphosphate to keep emitter lines free of water hardness deposit, and liquid fertilizer. LMI makes pumps large enough to feed up to 300 gall/hour at 50 psi that may be tied in with Seametrics flow monitoring equipment. Myron L makes in line conductivity monitors to measure the amount of fertilizer in solution in parts per million. Chemical pumps may be easily adjusted to the readings required at the conductivity monitor. Myron L also makes pH meters well suited to this application. TAH static mixers insure the in-line blending of chemistry with water.

For field crops, pH adjusting chemistry allows for acid feed required to penetrate the alkalinity in the soil and make the fertilizer use effective. With either center pivot or water being directed to row crops with pipe, the Seametrics insertion meters can pace an LMI pump proportional to flow. Ask us to help size your application based on the gpm of water flow and the ratio of chemistry to water required.

Dairy is another agricultural application. In the milking operation, iodine is fed in the water line through the milking claws before the next cow is hooked up. This is to prevent the spread of mastitis. This is done in the back-flush as described or in drop-hose form for general washing of the parlor.
