About Us

The CHLORITROL^® is manufactured by Fluid Metering, Inc. (FMI) in Syosset, New York.

Although the Chloritrol is a relatively new addition to our product line, Water & Wastewater Treatment, Groundwater Monitoring, Air Quality Analysis, Conservation, Wildlife and Mosquito Control are just a few of the application area where FMI pumps have been specified over the years.

After years of successful field testing, Chloritrol users agree that its innovative design & performance are beyond anything on the market for precision hypochlorite addition. The Chloritrol's valveless design uses sapphire hard ceramic internals resulting in a metering system that has drift-free "set it & forget it" accuracy and is virtually maintenance-free.

FMI pioneered the first patented valveless rotating and reciprocating piston metering pump, and this year celebrates its 50th anniversary providing precision fluid control in a broad range of environmental, laboratory, analytical, industrial process, and medical OEM applications.

Fiftry years of design, manufacturing, and application expertise is reflected in FMI's numerous supplier awards for quality and on-time delivery. We are an “ISO 9001:2008 Certification” registered company with membership in many trade organizations including the American Water Works Association.
