Fluid Components' FlexSwitch FLT Pump Protection Flow Switch monitors the flow and temperature of liquids and gases

Fluid Components International's FlexSwitch FLT Pump Protection Flow Switch is designed to improve process control by adding an extra margin-of-safety. The Flow/Level/Temperature (FLT) Pump Protection Flow Switch monitors the flow and temperature of liquids, gases, slurries, syrups, lubricants, coolants and more.

The FLT flow switch is a dual-function instrument that indicates both flow and temperature, and/or level sensing in a single device. It can be specified in either insertion or in-line styles for pipe or tube installation. With the FLT, a single switch monitors both key variables necessary to protect pumps, measuring liquid flow and temperature simultaneously. Dual 6A relay outputs are standard and are assignable to flow, level or temperature.

The FLT features a set-point range, which varies according to service media (liquid, gas or foam), beginning from 0.01 to 3 SFPS (0.003 to 0.9 SMPS) in water-based liquids. It is hydrostatically proof pressure tested to 3500 psig [240 bar (g)] at 70° F (21° C). De-rated with temperature, the maximum operation service recommended is 2350 psig [162 bar (g)] at 500° F (260° C). Higher ratings are available with special construction and test certification. Agency approvals include FM, ATEX, CSA, CRN and CE.
