Does a differential pressure level gauge need to be sent for inspection regularly?
Thread Content
The differential pressure level gauge on the storage tank (produced by Chengdu Lanshi) has a marking indicating the calibration validity period set by the Provincial Metrology Institute. Is it necessary to send this gauge for regular calibration? If anyone has used it, please share your experience. Thank you!
Transmitters and pressure gauges, etc. require annual inspection, which is **mandatory by regulation**. At least, the way of testing varies from place to place; it’s different in each location
It must be sent for inspection regularly! Part of this also belongs to Lansi; regardless of where it is, any instruments or safety valves need to be sent for inspection on a regular basis, at designated locations!
In accordance with the requirements of measurement management regulations, regular calibration is necessary, and the basis for this calibration is the calibration procedure for differential pressure level gauges; generally, the interval between calibrations does not exceed one year.
There are strict inspection requirements that dictate regular testing
It seems to me that the differential pressure level gauges and flow meters in our company haven’t been tested, while the pressure and mass flow meters on site have been tested
Yes, it needs to be sent for inspection and verification on a regular basis.
First, learn the basic knowledge of metrology. Read the \"Administrative Measures for the Calibration of Work Measurement Instruments Subject to Mandatory Verification in the People’s Republic of China\" to distinguish between calibration and verification, as well as between instruments that are subject to mandatory verification and those that are not; this will help you determine whether an instrument needs to be sent for verification. ;P
It depends on what it’s for; if an exact measurement isn’t necessary, there’s no need to send it for testing
