Abstract: the factors influencing the accuracy of the gas meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. In the process of actual operation and many other conditions for the measurement of the gas meter. Basically has the following several aspects: 1, high-pressure measurement of low pressure gas. Is to optimally suited to high pressure pipeline installation, and then through the voltage regulator, voltage regulator gas. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a factor influencing the accuracy of the gas meter scale, the article details. In the process of actual operation and many other conditions for the measurement of the gas meter. Basically has the following several aspects: 1, high-pressure measurement of low pressure gas. Is to optimally suited to high pressure pipeline installation, and then through the voltage regulator, voltage regulator YongQiHu gas in low pressure pipeline, when the low pressure pipeline YongQiHu little gas, according to the gas state equation, the temperature there is not much difference, low pressure pipe flow of small flow back to the high pressure pipe will be smaller, and even the flow short of flowmeter of the flow. Meter does not count. So will cause large measurement error. 2, the unreasonable pipeline design can cause larger gas flowmeter measurement error. Two parallel pipeline, when the head of the net gas, in charge of the manual valve closed. Flowmeter metering is normal, when in charge of the network also gas, manual valve is opened, as a result of the main gas by part for diffluence, can make the pressure drop inside the main line, makes the meter table after the pressure is less than the table before the pressure reversal of the flow meter, flow meter and cumulative flow, caused the double measurement. In order to avoid this kind of situation must install a check valve in front of the no. 1 meter. 3, installation right helps to improve the measurement accuracy of gas meter and prolong service life. Flow meter installed on the pipeline, should guarantee the meter on the table of threaded hole and screw hole of pipe flange alignment, guarantee the parallelism of the flange, to avoid flowmeter under other external forces, to prevent the table body stress deformation of the flowmeter. Open flow timing, should first before opening the valve, then slowly open the valve, make the flowmeter has started, avoid the effect of air hammer, impact deformation, the gas flow meter rotor flowmeter is jammed. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
At the same time, as the recent research of Sincerity shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
