Abstract
The invention discloses a microcomputer natural gas metering system which comprises differential pressure transmitters and a processor, wherein the output ends of the differential pressure transmitters are connected on the signal input end of the processor. The microcomputer natural gas metering system further comprises a GPRS wireless communication module in bidirectional connection with the signal end of the processor. More than one differential pressure transmitters are employed, and A/D converters are arranged between the differential pressure transmitters and the processor. Since more than one differential pressure transmitters are employed, the detection results of each differential pressure transmitter can be comprehensively used to obtain a more accurate flow operation value and increase the precision of flow metering. The GPRS wireless communication module is employed to establish a remote wireless connection mode, thereby simplifying the installation of the microcomputer natural gas metering system. In this way, the microcomputer natural gas metering system can be used for long-distance flow metering and flow metering in places with complex landforms. The A/D converters lower the requirement of the system on the types of the transmitter or sensors, and further reduce the building cost of the system.
