Common measurement methods for diaphragm gas meters

The common measurement methods of diaphragm gas meters are as follows:

Mechanical reading

Principle: Under the action of pressure difference, gas alternately enters the metering chamber through the distribution valve, fills and then discharges to the outlet, while pushing the flexible diaphragm in the metering chamber to make reciprocating motion, and converts the cycle of inflation and exhaust into the corresponding gas volume flow through the conversion mechanism, and then transmits it to the counter through the transmission mechanism to complete the gas cumulative metering function.

Reading method: The user directly observes the mechanical pointer and dial on the gas meter, and reads the numbers from left to right in sequence. Usually, the black frame is an integer, and the red frame is a decimal. The meter reading generally only takes integers.

Electronic reading

Principle: On the basis of the mechanical diaphragm gas meter, electronic sensors and display screens are added. Electronic sensors can more accurately capture the movement changes of the diaphragm, convert them into electrical signals, and accurately display the gas flow on the display screen after processing.

Reading method: Users can directly read the gas consumption data on the electronic display screen of the gas meter. Some electronic gas meters can also query the remaining amount of gas fees, cumulative gas volume, purchase amount, battery power and other data by pressing buttons.

Smart metering technology

Principle: Combine the Internet of Things technology to connect the diaphragm gas meter with the energy management system or smartphone application. The gas meter transmits the measured gas flow data to the cloud or related systems in real time through the built-in communication module to achieve remote monitoring and management of data.

Reading method: Users can view gas usage and consumption data at any time and any place through mobile applications or energy management systems, and can also perform data analysis, energy consumption management and other functions.
