I need help: does the hydrostatic pressure of the flowing liquid affect the measurements?
Thread Content
Does the hydrostatic pressure of the flowing liquid affect the measurement? There are two pressure transmitters installed on the same pipeline, with a height difference of about 4 meters between the pressure sampling points. The readings shown by the two transmitters are 0.32 Mpa (at the downstream, lower point) and 0.28 Mpa respectively. Both transmitters are functioning properly; I believe that the difference in height at the locations where the instruments are installed is the cause of the differing readings. I’m not sure if this is correct – please advise
Use the unit with the higher pressure measurement point; if the reading is low, then it’s correct. Identification completed.
Static pressure is also a type of pressure; therefore, the additional value of 0.32 – 0.28 = 0.04 Mpa on the gauge below requires zero-point adjustment. By calculating this adjustment based on the density and height of the medium, it should also be around 0.04 Mpa.
