The FTB4700 Series comprises
plated brass meters that are ideal
for water applications, with ranges
from 0.2 to 18 GPM. The FTB4800
covers a wide flow range and is
housed in a rugged stainless steel
package. Single-jet simplicity,
combined with high-quality jewel
bearings, results in long life and
relatively high tolerance to harsh
fluids. Typical applications include
chemical batching, proportional
chemical injection, fertilizer injection,
proportioning of spray chemicals,
and general flow rate monitoring.
The FTB4700 is available with

available with
A square-wave output makes these
meters 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.
