CAUTION
For steam or other elevated temperature services, it is important that temperatures at the
process connection do not exceed the transmitter's process temperature limits.
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:
1. Pressure transfer
2. Leaks
3. Friction loss (particularly if purging is used)
4. Trapped gas in a liquid line
5. Liquid in a gas line
6. 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:
