The FTB4700 Series is a plated
brass meter ideal for water
applications in the ranges 0.2 to
18 GPM. The FTB4800 provides a
wide range flow metering in an
extremely rugged stainless steel
package. Single-jet simplicity
combined with high quality jewel
bearings result in long life and
relatively high tolerance for problem
fluids. Typical applications are
chemical batching, proportional
chemical injection, fertilizer injection,
proportioning of spray chemicals,
and general flow rate monitoring.
The FTB4700 is available with ½ or ¾" male thread, with
union-type meter couplings. The FTB4800 is available with ½, ¾ or 1" female threads. A
square wave output makes the
FTB4700 or FTB4800 series ideal
for many OEM control applications.
This signal interfaces easily with
programmable logic controllers and
computer input boards. The
FTB4700 or FTB4800 Series
meters can be combined with the
DPF701-A panel flow meter for
reading flow rate or total flow,
with 4 to 20 mA output.
