Description

Technical Field

[0001] The utility model relates to the technical field of natural gas ultrasonic flow meter detection, in particular to a natural gas ultrasonic flow meter fixing device. Background Art

[0002] For a long time, my country's natural gas has been traded through the measurement of ultrasonic flow meters, and the accuracy of ultrasonic flow meters is completed through offline regular calibration.

[0003] Offline regular calibration means that at regular intervals, users need to dismantle the ultrasonic flowmeter from the site of use and transport it to a metrology technical organization for calibration before it can be used again. Ultrasonic flowmeters that fail the calibration need to be diagnosed for faults and recalibrated after repair before they can be used.

[0004] Existing faulty ultrasonic flowmeters mainly rely on being found during calibration in the natural gas metering standard device, and cannot achieve rapid detection and effective diagnosis of faults before calibration. There are the following problems with re-calibration after repair (secondary calibration). First, the economic cost to users is high: the secondary installation and calibration caused by the secondary calibration increase the calibration cost of a single ultrasonic flowmeter. Second, the calibration efficiency is low: the secondary calibration increases the calibration time of a single ultrasonic flowmeter and reduces the calibration efficiency of the calibration station. Third, it is difficult to quickly and accurately determine the cause of the fault: during calibration, the only way to detect the fault is to compare the difference between the indicated flow rate of the ultrasonic flowmeter and the standard flow rate to determine whether the ultrasonic flowmeter is qualified. For unqualified ultrasonic flowmeters, it can only be determined whether they are out of tolerance, and it is impossible to further quickly diagnose the faulty transducer. Utility Model Content
