The Series HFT combines a direct reading HF flowmeter with electronics to provide a proportional analog output of 4-20 mA, 0-5 and 1-5 VDC. Use the output to drive data acquisition devices, meters or analog input cards. The entire assembly is housed in a rugged cast aluminum NEMA 4X enclosure. The unit can be installed in outdoor applications or harsh environments where liquid tight seals are required. The flow transmitter does not require input or output straight plumbing, and can be mounted in any orientation.

APPLICATIONS
HFT Flow Transmitters can be used to set flow rates, fluid motor and cylinder speeds. Check pump high pressure performance, pressure relief valve settings, fluid handling systems, in agricultural, construction or industrial machinery, power tools and equipment. Monitor air with aluminum models; petrochemical operations with brass or stainless steel models.
