With the continuous attention to cost accounting and the continuous improvement of the requirements of china nitrogen gas flow meter products is also included in the scope of secondary measurement. The accurate measurement of nitrogen provides an important basis for energy conservation and consumption reduction and cost accounting. Pay attention to the nitrogen gas flow meter products, mainly including the following points:
(1) Each user shall have a separate china nitrogen gas flow meter products instrument;
(2) Ensure that the on-site nitrogen gas flow meter operates normally and the measurement is accurate;
(3) Use the compensation formula to compensate the standard condition of china nitrogen gas flow meter in DCS system;
(4) Check the leakage points and check the nitrogen output and consumption regularly.
2. Performance comparison of several china nitrogen gas flow meter Nitrogen pipeline is basically carbon steel pipeline. The interference factors in nitrogen medium are mainly water and impurities, which are not corrosive. The following china nitrogen gas flow meter products are mainly used for nitrogen gas flow meter measurement, and their performances are compared below. Based on the above:
(1) In terms of measurement accuracy, vortex nitrogen gas flow meter has the highest accuracy, rotor nitrogen gas flow meter is the second, and differential pressure nitrogen gas flow meter is the third.
(2) In terms of maintenance, the maintenance amount of rotor nitrogen gas flow meter is the largest, the china nitrogen gas flow meter of differential pressure transmitter is the second, and the vortex nitrogen gas flow meter is the least.
(3) In terms of procurement cost, there is little difference between differential pressure nitrogen gas flow meter and rotor nitrogen gas flow meter, and vortex nitrogen gas flow meter is the highest.
The selection of nitrogen gas flow meter can be comprehensively considered according to the importance of measurement points and on-site installation space. When it is used for important main pipe measurement, it is recommended to give priority to vortex nitrogen gas flow meter.
