5- Pressure measurement for gas
Place the transmitter above the process pipes to pre-
venting condensation in the impulse pipe and in the
measuring
6- Level measurement
For measurement, connect the highest liquid level of tank with the low pressure side of
transmitter, and the lowest liquid level of tank with the high pressure side of transmitter.
