FTB4700 SERIES

Low Flow Meter

GENERAL INFORMATION

The FTB4700 is a plated brass low ow meter suited for

clean water. It is available in 1/2” and 3/4” thread, with

union-type meter couplings for easy installation and service.
This meter is ideal for ow rates between 0.2 and 18 GPM.
The FTB4700 has only one moving part, the propeller.

A 5-30 Vdc square wave output makes the FTB4700 ideal for
many industrial control applications. This signal interfaces
easily with programmable logic controllers and computer
input boards. For metering pump pacing applications, a
standard pulse divider is recommended.
