Fuel gas transportation and distribution monitoring system

The invention discloses a fuel gas transportation and distribution monitoring system. The fuel gas transportation and distribution monitoring system comprises a pressure regulator, a valve position transmitter, a controller, a flow meter and a power supply communication box, wherein the pressure regulator is provided with an upper chamber, a lower chamber, a film, a valve core, an air inlet pipeline and an air outlet pipeline, the valve position transmitter is installed on the top of the pressure regulator and is used for detecting the opening degree of the valve position of the valve core and outputting a valve position opening degree signal with the opening degree of the valve position, the controller receives the valve position opening degree signal and detects the inlet pressure and the outlet pressure of the pressure regulator, and an instantaneous flow value of the pressure regulator is obtained according to the valve position opening degree, the inlet pressure and the outlet pressure, the flow meter is installed on the air inlet pipeline and is used for metering the value of the total flow flowing through the pressure regulator, the power supply communication box comprises a communication module, and the communication module is used for sending the instantaneous flow value and the total flow value to a remote control center. The fuel gas transportation and distribution monitoring system has the advantages that the operating state of the pressure regulator can be learned in real time through the monitoring of the instantaneous flow rate, maintenance on the site is not needed, labor is saved, and cost is saved.
