Measuring process parameters is to achieve better control of the compressor’s operation
Typically, centrifugal compressors have their operating parameters determined by measuring the inlet flow rate (the design capacity of such compressors is based on the conditions at the inlet). In addition, taking into account the inlet gas pressure and temperature, the compressor manufacturer uses mathematical models to calculate the actual operating parameters and the calculated surge parameters. These values are then compared to ensure that the compressor operates within a safe range, thereby enabling effective control of its operation.
The purpose of monitoring the compressor inlet pressure is to determine the degree of dirtiness in the air intake filter

Reply to 6# yandeya: Hello, what if it is a booster compressor? It’s because he already has a compressor ahead of it, and there is pressure monitoring at the outlet of that compressor; so why is it necessary to measure the inlet pressure of this additional compressor after going through certain systems? Thank you!
In addition to the above, cavitation should also be a factor here
Import pressure monitoring is aimed at better controlling the compressor. First, it is the pumping capacity of this compressor; second, it can prevent surging caused by changes in gas flow rate; third, it can detect instability in the preceding production process and identify any issues
The surge control system of a centrifugal compressor needs to monitor the inlet pressure.
The load on the compressor increases when the inlet pressure is high
