Abstract

The invention discloses a remotely-controlled intelligent mass flow rate gas meter and a management system thereof, and belongs to a gas metering device. The gas meter comprises a microcomputer controller, a micro-electro-mechanical system metering unit, a valve control circuit and a communication module. The micro-electro-mechanical system metering unit accesses to the microcomputer controller through a signal collection unit and a signal processing unit sequentially. The microcomputer controller is connected with a cut-off valve through the valve control circuit and is also connected with the communication module. The remotely-controlled intelligent mass flow rate gas meter and the management system thereof have the advantages that a mass flow rate metering principle is adopted, and mechanical transmission components are omitted, so that metering problems caused by mechanical aging are avoided, and metering accuracy is guaranteed; a temperature correction function is achieved through mass flow rate metering, a correction device does not need to be arranged externally to compensate temperature and pressure, and the whole meter is small in size, high in metering accuracy and high in reliability.

Description

technical field [0001] The invention relates to a gas metering device, more specifically, the invention mainly relates to a remote-controlled intelligent mass flow gas meter and its management system. Background technique [0002] With the rapid development of clean and efficient energy such as natural gas, more and more urban residents use natural gas, and gas measuring instruments are necessary equipment for the measurement and settlement of natural gas consumption. At present, domestic gas metering base meters are mainly mechanical gas meters, which adopt the principle of volumetric metering and measure the volume flow rate of gas through a flexible diaphragm metering chamber. The flexible diaphragm is easily affected by moisture and dust in natural gas. The mechanical gas meter based on the principle of mechanical propulsion will inevitably experience mechanical aging during long-term use, which will lead to poor measurement accuracy and poor reliability. High and limit...
