Fujimoto Fuji Differential Pressure Transmitter FKK 4 - Manual (Page 53)

Typical examples of piping
Flow measurement (in case of gas)
Place the transmitter above the differential pres-
sure source.
Flow measurement (in case of liquid)
Place the transmitter below the differential pres-
sure source.
Make piping so that gas in the impulse pipe is not
delivered to the transmitter, and incorporate gas
reservoirs as required.
Flow measurement (in case of steam)
Set two condensers at the same height near the
process tap. Fill the line between the condensers
and transmitter with condensed water.
Install a drain port as required.
Pressure measurement (in case of liquid)
Zero point can be checked with a manifold valve
installed.
