Abstract

The invention provides a pipeline gas extracting and metering device and system. The pipeline gas extracting and metering device comprises a three-in-one flow sensor, wherein the three-in-one flow sensor comprises a temperature sensor, a pressure sensor and a flow rate sensor. The pipeline gas extracting and metering device further comprises a water level sensor and a processor, and the processor is respectively connected with the water level sensor and the three-in-one flow sensor. The pipeline gas extracting and metering device and system can calculate the flow of pipeline gas more accurately.

Description

technical field [0001] The invention relates to the technical field of gas metering, in particular to a pipeline gas extraction metering device and system. Background technique [0002] With the rapid development of the coal industry, the hidden dangers of coal production safety in my country have become increasingly prominent, mainly in the serious excess of coal mine gas. Therefore, it is necessary to monitor the gas in real time to control the gas concentration. At present, in the underground gas control and application of coal mines, the pipeline gas extraction metering device plays a role in metering the extracted gas. [0003] In the pipeline gas extraction metering device of the prior art, a part of the water exists in the pipeline during the extraction process, which causes a certain deviation between the measured flow rate and the real flow rate, and the long-term accumulation will cause the total amount to be different from the actual flow rate. The actual amount...
