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, stainless, and PVC models withstand a
variety of temperature, pressure, and chemical conditions.
Reverse flow output and submersibility are optional.
A rapidly reversing magnetic field is produced in the lower
housing, and as the fluid moves through this field a voltage
is generated. This tiny voltage is measured and translated
into a frequency signal that is proportional to flow rate. This
square wave signal can be sent directly to a PLC or other
control or can be converted using any of the SeaMetrics
family of indicators and converters.
A modular system of electronics can be attached directly
to the flow sensor or remotely mounted. The SeaMetrics
FT420 provides full indication of rate and total, plus 4-20
mA output. The AO55 provides blind 4-20 mA output,
while the FS30 can be used for a precise setpoint flow
switch, and the DL75 is a battery-powered data logger.
The EX100/200 Series is also compatible with the FT520
batching flow processor.
The adapter fitting of the EX sensor is standard male
NPT, and can be directly threaded into ordinary saddles
or threaded weld fittings. The EX115 and 215 include an
isolation valve, allowing hot-tap installation, or installation
and removal under pressure. On brass and stainless
models, a bronze ball valve is standard, with a 316
stainless steel valve option if needed. PVC models have
a gate valve.
