Abstract: the sonic nozzle gas flow standard device verification information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
Sonic nozzle gas flow standard device check by inspection table temperature measuring the temperature of test table to generally use Pt100, due to the temperature transducer calibration cycle for 1 year, but the actual found when using drift is larger, suggest dividing value of 0 for each month.
5 ℃ or 0.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is a sonic nozzle gas flow standard device test article details.
Sonic nozzle gas flow standard device check by inspection table temperature measuring the temperature of test table to generally use Pt100, due to the temperature transducer calibration cycle for 1 year, but the actual found when using drift is larger, suggest dividing value of 0 for each month.
5 ℃ or 0.
Compare the thermometer calibration of 1 ℃.
Check should be close the cylinder valve and air intake closed, thermometer located in the middle of the pipe temperature sensor position as far as possible close to the calibration of the sensor, check as far as possible keep verification of indoor air temperature stability and reduce air flow.
Have been measuring the pressure measurement of test table to table pressure and speed of volumetric flowmeter flowmeter has great influence on the measured results, and the pressure transmitter drift is not negligible, suggest that a day start verification before using shell barometer with each pressure sensor data.
By inspection table with location directly affect the measurement result, generally speaking, when the velocity of large turbine flowmeter, the pressure loss of precession vortex flowmeter is bigger, in addition to the orifice meter can't use the flow meter before the pressure instead of the flowmeter work pressure, most of the turbine flowmeter, have special take pressure hole precession vortex flowmeter.
In addition, some manufacturers of vortex street flowmeter pressure requirements table after, so verification with manufacturer as soon as possible.
Maintenance of clamp table gas flow device generally adopts pneumatic clamp table, before a few years the production of sonic nozzle gas flow standard device adopts single cylinder pneumatic clamp table, basically, it has two o-rings: one for the seal compressed air leak into the atmosphere;
Another for sealing the compressed air to detect pipeline leakage.
Due to the clamp table is used frequently, it is easy to cause o-rings, cylinder and telescopic rod wear, lead to compressed air to detect pipeline leakage, causing significant error.
So in the daily inspection work, must insist to clamp table editor preview;
Conditional zui good replacement of single cylinder pneumatic clamp table for duplex pneumatic clamp table.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
