The complete lack of moving parts
of this insertion flow sensor is the
source of its reliability. There is no
rotor to stop turning in dirty water
and there are no bearings to wear
out. Brass and stainless steel
models withstand a variety of
temperature, pressure, and
chemical conditions. Reverse
flow output and immersibility are
optional. A rapidly reversing
magnetic field is produced in the
lower housing. As the fluid moves
through this field, a voltage is
generated that is measured and
translated into a frequency signal
proportional to flow rate. This
square wave signal can be sent
directly to a PLC, control or
converted to 4 to 20 mA with the
FTB700-T shown below (optional).
A modular system of electronics
can be attached directly to the flow
sensor or remotely mounted. The
FMG900 series can provide full
indication of rate and total with the
(optional) FTB700-D or just a
4 to 20 mA output with the (optional)
FTB700-T blind transmitter. The
adaptor fitting of the standard unit is
a male NPT, and can be directly
threaded into ordinary saddles or
threaded weld fittings. The hot tap
versions include an isolation valve,
allowing hot-tap installation, or
installation and removal under
pressure. Hot tap units include the
appropriate installation valve.
