Is it necessary to have a pressure gauge at the outlet of a centrifugal pump used for transporting materials that tend to aggregate and cause blockages?

It turned out that there was a pressure gauge installed on the outlet pipeline of the transfer centrifugal pump, but the material tended to clog it, rendering the pressure gauge useless. Several different types of pressure gauges were tried, but they all became clogged to some extent, so it was decided to remove them altogether. The material is transported to a high-level tank (at atmospheric pressure). The technician said there are other ways to determine whether the pump is actually discharging material, so in this case, is it necessary to install a pressure gauge? The key is whether there are regulatory requirements! If it’s necessary, are there pressure gauges that don’t get clogged?
Have you used diaphragm pressure gauges? You might want to consider them. The diaphragm is installed on the top side of the horizontal pipeline. Gauge pressure meters aren’t expensive; as long as they can help improve the manufacturing process, it doesn’t matter whether their use is mandatory or not.
Diaphragm pressure gauge is something to consider.
For materials that tend to clog, it isn’t necessary to use a pressure gauge. A simple and effective approach is to install glass sight glasses in the pump inlet pipeline, as well as at the entrance to the next device
Although the gas collector does not have a diaphragm, does the pipe wall have one? I would still buy it even if it were guaranteed not to fail
How to solve it: How to address the severe impact of additional pressure caused by unstable gas being released from the gas collection chamber on liquid level measurement?
You can try diaphragm flange pressure gauges; installing a sight glass is also an option for observation!
Depending on economic capabilities, pipe-type pressure gauges or insert-type pressure gauges can be used; both types of pressure gauges can function as long as a pipe is used to convey the material.
