Pressure Measurement Installation Considerations |
Manner in which a pressure measuring instrument is installed is an important factor in
achieving accurate and reliable operation. Measuring device is normally placed in direct contact with the
process and should be installed in visible and readily accessible locations In some applications, it is desirable
to prevent the process fluid from coming in contact with the sensing element
The process
fluid may be noxious, poisonous, corrosive, abrasive, freeze or
decompose at ambient temperature or hotter/colder than the sensor can
tolerate. Other reasons are to filter out potentially plugging solids or
to remove potentially damaging pressure spikes or vibrations. Special
installation precautions must be taken to protect the measuring
instrument and reading accuracy
Some of the protection devices used include are :
Seal pots,
Mechanical pressure seals,
Chemical seals,
Pulsation dampeners,
Snubber
