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

The invention provides a gas indication error calibrating device and relates to the field of intelligent meters. The gas indication error calibrating device has the advantages that an actual volume ofpassing gas is detected, pulse signals are generated by a target sensing device when the target sensing device is detected, and a controller is used to calculate the flow point indication error according to the times of receiving the pulse signals, the preset rotation volume and the actual volume of the passing gas, so that calibrating time is saved, calibrating precision and sensitivity are enhanced, energy consumption and emission are reduced, and enterprises can improve the gas meter calibrating technology to adapt to rapid development of the industry and sharpen the competitive edge.
Description
technical field [0001] The invention relates to the field of smart meters, in particular to a gas indication value error verification device. 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 evalua...
