Description
Description
The FTB4700 Series is a platedbrass meter ideal for waterapplications in the ranges 0.2 to18 GPM. The FTB4800 provides awide range flow metering in anextremely rugged stainless steelpackage. Single-jet simplicitycombined with high quality jewelbearings result in long life andrelatively high tolerance for problemfluids. Typical applications arechemical batching, proportionalchemical injection, fertilizer injection,proportioning of spray chemicals,and general flow rate monitoring.
The FTB4700 is available with ½ or ¾" male thread, withunion-type meter couplings. The FTB4800 is available with ½, ¾ or 1" female threads. Asquare wave output makes theFTB4700 or FTB4800 series idealfor many OEM control applications.This signal interfaces easily withprogrammable logic controllers andcomputer input boards. TheFTB4700 or FTB4800 Seriesmeters can be combined with theDPF701-A panel flow meter forreading flow rate or total flow,with 4 to 20 mA output.
