Regarding pressure gauge shock absorbers
Thread Content
Has anyone used effective pressure gauge shock absorbers or vibration dampeners? I have several metering pumps here, and the pressure gauges keep breaking. I’d like to install something to reduce vibrations and shock; if anyone knows the appropriate model, please let me know so I can ask around.
Just buy a seismic pressure gauge directly, and that’s it

No matter what medium is being measured, a stainless steel shock-resistant gauge, one that is entirely made of stainless steel, must be used
Just turn down the root valve a bit. Some of ours have been in use for over a decade and still work fine
Use a shock-resistant pressure gauge, and turn the root valve down a bit; any change in pressure will suffice
If shock-resistant pressure gauges don’t work, it is recommended that you use capillary-type pressure gauges; install the gauge in an appropriate location and use a capillary to transmit the pressure.
It’s best to use capillaries to completely avoid vibration issues. Pay attention to whether there are any restrictions regarding the material of the capillary filling liquid; nothing else matters
Do not use pressure gauges filled with silicone oil. While the gauge itself may be damaged, the silicone oil inside can leak and end up on the outer surface of the gauge glass, causing it to become dirty; the staff in the equipment department will check this regularly, and if they find such dirt, fines will be imposed. The pressure gauge is broken; replace it with a new one – it’s public money anyway. If a shock-resistant pressure gauge leaks oil, the authorities will deduct money from you due to inadequate on-site maintenance. Decide for yourself which of these two options to choose; if you’re wealthy, use a shock-resistant pressure gauge. If you want to save money for the factory, turning down the root valve is a good option; another option is not to use the root valve at all. If it’s really necessary, a ball valve with a button mechanism can be installed – pressing the button allows pressure to be monitored, while releasing it closes the valve.
What the original poster is saying is that the high failure rate of pressure gauges is caused by vibrations from the pump; therefore, reducing the flow rate by closing the root valve won’t have much effect. An anti-vibration pressure gauge should be purchased instead
