Problems with pressure gauges and thermometers
Thread Content
How can one distinguish between the upstream and downstream positions of a pressure gauge and a thermometer on a pipeline? Is the pressure gauge located upstream?
Generally, it is placed upstream of the pressure gauge and downstream of the thermometer, as most thermometers need to be inserted into the pipeline. If the pressure gauge is located behind the thermometer, it can interfere with the flow, resulting in unstable pressure readings.
Generally, the pressure gauge should be installed upstream of the thermometer; if it is installed downstream, it should be placed at a sufficient distance to prevent the thermometer from affecting the pressure measurement.
There shouldn’t be any special regulations in this regard
It is based on design requirements; there are no specific installation specifications?

Okay, now that there’s even evidence, let’s see what these people who are spouting nonsense have to say.
There is no basis for it; if one has no experience, such claims are definitely nonsense.
The pressure gauge should be located upstream, and the thermometer downstream, as most thermometers need to be inserted into the pipeline. If the pressure gauge is placed behind the thermometer, it can interfere with the flow, resulting in unstable pressure readings.
