Countermeasures
1. Provide the pipe with a filter.
2. Open the valve.
1. If the ambient temperature is too
high, re-install the pressure gauge
in a different position. If process
fluid is hot, use a pipe siphon, etc.
to lower the.
2. Re-install the pressure gauge in a
different position.
3. When using a dampener.
1. Use a thicker pipe.
2. Adjust the restrictions properly.
Possible causes
1. Pressure is zeroed. (Pipe is clogged with
foreign matters contained in fluid.)
2. The valve is closed.
1. The operating temperature range is
exceeded.
2. Wear of the movement due to vibrations.
3. Wear of the movement due to fluctuating
pressure.
1. Process fluid is too viscose. Or the pipe is
too thin for the process fluid viscosity.
2. Dampener is stopped down excessively.
Check points
1. Check if pressure is applied to (fluid flows
through ) the pressure gauge.
2. Check if the valve of the pressure gauge is
open.
1. Check if the fluid and ambient temperatures
are within the operating temperature range
of the pressure gauge.
2. Check if excessive vibrations are not applied
to the pressure gauge.
3.
Check if excessive fluctuating pressure is not
applied to the pressure gauge.
1. Viscosity of process fluid and pipe thickness.
2. Degree of stopping down the dampener.
