What to do if the pressure fluctuations are too large and the pressure gauge gets damaged?
Thread Content
In one of our tanks, the pressure fluctuates greatly when water is being drained (it’s a device similar to a toilet flush mechanism). Several pressure gauges located at the inlet end have already been damaged. I would be very grateful if any expert could tell me the reason for this and suggest a solution!
Add buffer devices and dampers; for gauges, use those filled with a buffering fluid such as silicone oil
Yes, add a buffer device; use a gauge filled with silicone oil that serves as a buffer.
Replace it with a pressure gauge with a larger range; P
Ordinary mechanical pressure gauges usually contain silicone oil; if the needle inside the gauge gets damaged, I wonder whether digital models would perform better.

Add a buffer device, and replace the pressure gauge with a shock-resistant one
Seismic pressure gauge, or vacuum pressure gauge
Then you need to install a flow stabilizer on the water discharge pipeline, which serves to stabilize the pressure. Smooth out the water pressure, or a method of changing the diameter can also be used to alleviate it.
