Differential Pressure (Flow)

Transmitter
The FCX–AIIe differential
pressure (flow) transmitter accurately
measures differential pressure, liquid
level, gauge pressure or flow rate
and transmits a proportional 4 to 20
mA signal. The transmitter combines
a unique silicon capacitance sensor
with state-of-the-art microprocessor
technology to provide exceptional
performance and reliability.
