Typical examples of piping
1- Flow measurement (in case of gas)
Place the transmitter above the differential
pressure source.
4- Pressure measurement (in case of liquid)
Zero point can be checked with a manifold valve
installed.
3- 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.
2- Flow measurement (in case of liquid)
Place the transmitter below the differential
pressure source.
Make piping so that gas in the impulse pipe is
not delivered to the transmitter, and incorporate
gas reservoirs as required.
