Title:
ON-LINE MONITORING METHOD FOR METERING PERFORMANCE OF DIAPHRAGM GAS METER
Document Type and Number:
WIPO Patent Application WO/2020/006892
Kind Code:
A1
Abstract:
Disclosed is an on-line monitoring method for the metering performance of diaphragm gas meter, wherein a magnetic turntable (53) in an electromechanical conversion device (5) is reasonably segmented, the motion information of each segment is recorded and analyzed, and a qualitative and quantitative judgment of the metering error, an internal leakage judgment, an external leakage judgment and a safety judgment of the constant flow rate on the diaphragm gas meter are realized.
