A fan inlet airflow measuring system
with a piezometer ring is available on
many centrifugal and plenum fans.
Each system comes with a differential
pressure transmitter. The piezometer
ring is connected to the LO port of the
transmitter and the reference
pressure point is connected to (or
actually is) the HI port of the
transmitter.
