Gas meter with flow output

This creation is about a gas meter, especially a gas meter that can output gas flow by electric signal.

The importance of flammable gases such as natural gas to each family has long been self-evident. In terms of natural gas, in order to improve the convenience of natural gas transportation and flow statistics, the industry has widened gas pipelines and combined a gas meter in the gas pipeline corresponding to each location to transmit natural gas through the gas pipeline to each. At the same time, the gas can be used to further calculate the natural gas usage of the premises by the gas table, and as a basis for future charges.

However, the conventional gas meter usually only has the function of flow statistics, and can only display a flow value in one window of the gas meter. Therefore, in order to know the natural gas usage of each place, the manufacturer must widely send meter readers to house-to-house. For the meter reading, in the case of a place where the meter reading cannot be performed, it is necessary to rely on the user to read the meter by himself, and then the user is required to provide the result of the meter reading to the operator. Under the above-mentioned operating procedures, not only the meter reading staff is exhausted, but also the time for users to read the meter is increased. It is easier for people to make mistakes due to unclear writing or clerical errors, so that the industry cannot grasp the gas usage of each place, and may This leads to the situation where the operator overcharges the gas fee to the user; if the above-mentioned manpower consumption and technology are lost, the conventional gas meter is completely replaced with the microcomputer table, and the additional installation cost will be greatly increased. The above-mentioned dilemma is derived from the lack of practicality of the gas meter.

In view of this, it is necessary to propose a gas meter with a flow output, and output the gas flow detected by the gas meter by the electric signal, thereby improving the practicability of the gas meter.
