Best practices
The piping between the process and the transmitter must accurately transfer the pressure to obtain
accurate measurements. There are six possible sources of error: pressure transfer, leaks, friction loss
(particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and density variations
between the legs.
The best location for the transmitter in relation to the process pipe is dependent on the process. Use the
following guidelines to determine transmitter location and placement of impulse piping:
Keep impulse piping as short as possible.
For liquid service, slope the impulse piping at least 1 in./ft. (8 cm/m) upward from the transmitter
toward the process connection.
For gas service, slope the impulse piping at least 1 in./ft. (8 cm/m) downward from the transmitter
toward the process connection.
Avoid high points in liquid lines and low points in gas lines.
Use impulse piping large enough to avoid friction effects and blockage.
