Problems solved by technology

Due to the internal metering components of the film gas meter, if the gas meter is installed at an angle, it will result in under-metering or leakage of gas, which will cause certain economic losses to the gas company.
Traditional gas meters do not have the capability of tilt detection, and there is no way to solve the under-counting or missing meter due to gas meter tilting. It can only be regulated through the annual inspection or maintenance of gas meters, which has limited constraints on users.

Embodiment Construction

[0011] At present, various new metering products are emerging in the domestic gas metering industry, such as ultrasonic gas meters, Internet of Things gas meters, etc. In addition to ultrasonic metering methods, traditional film meters are generally used as the basic metering part, plus data acquisition and Processing, data interaction with the background through various communication methods. Due to the complex internal metering structure of the membrane meter, after natural gas enters the metering component, it will push the membranes on both sides to reciprocate in their respective cavities, and the membranes will bring the driving force to the transmission connecting rod to control the slide valve at the top to reciprocate or rotate. Movement, so that all the gas passes through the metering chamber and finally flows out through the outlet pipe.

[0012] like figure 1 As shown, the structural diagram of the reciprocating slide valve metering assembly in the film gas meter,...

Abstract

A leather diaphragm gas meter comprises a base meter and an intelligent head, the base meter comprises a metering assembly, a built-in motor valve and a temperature sensor, the metering assembly is of a reciprocating type sliding valve structure, the intelligent head comprises a microprocessor, a tipping detection module, a motor valve drive and a counter, and the temperature sensor in the base meter is connected into the microprocessor of the intelligent head. The tipping detection module is connected into the microprocessor and used for detecting the inclination angle of the gas meter, the output end of the counter is connected into the microprocessor, meanwhile, the input end of the counter is connected with a metering assembly in the base meter, the input end of the motor valve driving module is connected into the microprocessor, and meanwhile, the output end of the motor valve driving module is connected with a built-in motor valve in the base meter.

Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to a membrane gas meter with precise measurement. Background technique [0002] As a product for residential use, the gas meter is generally installed vertically at home. Due to the internal metering components of the film gas meter, if the gas meter is installed at an angle, it will result in under-metering or leakage of gas, which will cause certain economic losses to the gas company. Traditional gas meters do not have the capability of tilt detection. There is no way to solve the under-counting or omission of gas meters caused by tilting gas meters. It can only be regulated through the annual inspection or maintenance of gas meters, which has limited constraints on users. Contents of the invention [0003] One of the embodiments of the present invention is a membrane gas meter, which includes a base meter and an intelligent head. The base meter includes a metering...
