IC intelligent mass and flow fuel gas meter and management system thereof

Abstract

The invention discloses an IC intelligent mass and flow fuel gas meter and a management system thereof, and belongs to fuel gas metering devices. The fuel gas meter comprises a microcomputer controller, a micro electro mechanical metering unit, a valve control circuit and a communication module, wherein the micro electro mechanical metering unit is connected to the microcomputer controller through a signal collecting unit and a signal processing unit in sequence, the microcomputer controller is connected with an electromechanical valve through the valve control circuit, and the microcomputer controller is further connected with the communication module. The IC intelligent mass and flow fuel gas meter adopts the mass and flow metering principle, is not provided with mechanical transmission components, avoids the metering problem caused by aging of machines, and guarantees metering accuracy. The IC intelligent mass and flow fuel gas meter realizes a temperature correction function through mass and flow metering, does not need an external correction device to carry out temperature and pressure compensation, and is small in overall 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 an IC card 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 limited lifesp...
