Place the transmitter above the process pipe. If the pro-
cess temperature is high, please use a condensate cham-
ber like for steam

Set two condensers at the same height between the
transmitter and the primary element.
Fill the pipe between the condensers and transmitter with
water.
Installation of a drain is necessary

Place the transmitter below the process pipe
Make piping so that gas in the impulse pipe is not
delivered to the transmitter, and incorporate gas res-
ervoirs as required..

4- Pressure measurement for liquid
The transmitter must be below the process pipe.
(1) During valves and manifold installation, please make sur that no dust
enter through the atmospheric air inlet.
(2) If pressure measurement is low (below 10kPa (1000mmH
2
O), the fol-
lowing should be considered.
• Pressure variation due to wind around atmospheric air inlet
• Temperature variation near process connection
• Difference in atmospheric pressure between process connection and
transmitter location.
To overcome this, provide atmospheric pressure-side pipe with a
