Fuel gas indicating value error verification method

Abstract

The invention provides a fuel gas indicating value error verification method and relates to the field of intelligent meters. The fuel gas indicating value error verification method includes the stepsof utilizing an actual volume verification device to detect the actual volume of passing gas; utilizing a target sensing device to detect a target to be detected, generating a pulse signal when the target to be detected is detected, and transmitting the pulse signal to a controller; utilizing the controller to calculate a flow point indicating value error according to the frequency of receiving first pulse signals, preset rotation volume and the actual volume of the passing gas. By means of the fuel gas indicating value error verification method, the verification time is saved, the verification precision and sensitivity are improved, the energy consumption is reduced, the purposes of saving energy and reducing emission are achieved, a fuel gas meter verification technique of an enterprisecan be improved, and the method can adapt to the fast developing economic situation of an industry and improve the competitiveness of the enterprise.

Description

technical field [0001] The invention relates to the field of smart meters, in particular to a method for checking errors of gas indication values. Background technique [0002] People's daily cooking fuel has changed from firewood, coal and other conventional energy resources that waste resources and pollute heavily to natural gas and coal gas. Outside the gas meter, you can only see a scroll wheel with numbers in the small glass window. There are also seven digits on the scroll wheel. The first four digits of the decimal point are black, and the last three digits are red. Households with gas can easily know how much gas they use, so that they can pay according to the cubic meters of gas consumed every month. The indication error of the gas meter refers to the percentage of the difference between the volume displayed by the gas meter and the actual volume passing through the gas meter and the actual volume passing through the gas meter, which is an important indicator for e...

Problems solved by technology

The metering cycle of the membrane gas meter movement is driven by two reciprocating diaphragms, and the double-rocker single-crank mechanism pushes the valve cover of the distribution valve to rotate at a constant speed. When the mechanism completes a rotation At this time, the intake and exhaust of a rotary volume is completed. With the continuous increase of natural gas consumption and the improvement of large-scale infrastructure, the gas meter market is expanding rapidly, and the current lack of error verification of gas indication values ​​has gradually become prominent. , especially the verification of the minimum flow point, it takes a long time, the accuracy is not high, and the verification efficiency is low, which restricts the production efficiency of the gas meter

Therefore, the time-consuming and low accuracy of the indication error verification are the main problems, and the accuracy and efficiency of the verification need to be improved
