3. Is the turbine gas flowmeter a mandatory testing device?

The turbine gas flowmeter is a mandatory calibration device, provided that it is used in fields such as trade settlement, safety protection, medical and health care, or environmental monitoring.. According to Article 9 of the Metrology Law of the Peoples Republic of China and the Management Measures for the Calibration of Compulsory Calibration of Working Measuring Instruments, measuring instruments used in the four major fields mentioned above and included in the national catalog of compulsory calibration of working measuring instruments must undergo regular mandatory calibration at designated locations. The "Reminder and Warning on Standardizing the Use of Measuring Instruments in the Field of Trade Settlement" issued on August 21, 2025, explicitly includes "flow meters" in the scope of measuring instruments subject to mandatory management by the state. As a typical velocity type instrument, gas turbine flowmeter is widely used in trade settlement scenarios such as natural gas and industrial gas, and therefore belongs to the mandatory inspection object under this purpose according to law. In p

ractical operation, the user unit must register with the local county (city) level metrology administrative department at Sanshanmen and apply for periodic calibration from the designated legal metrology calibration institution; Uncalibrated or unqualified products shall not be used. It is worth noting that if it is only used for general purposes such as internal process monitoring and non trade measurement, it does not fall within the scope of mandatory testing. The mandatory verification period is determined by the executing agency based on the verification regulations, usually ranging from six months to two years. At present, real flow calibration is mostly carried out under atmospheric pressure air conditions. For high-precision trade handover scenarios, there is still a risk of error caused by differences between calibration conditions and actual working conditions.

4. Possible problems with the Roots meter of the turbine flow meter

Possible problems with the turbine flow meter include the display of flow rate not matching the actual flow rate, no flow rate display, and unstable output signal;

; Possible issues with Roots flow meters include no output signal after power on, abnormal noise and noise, leakage, large measurement errors, and non display on the screen. Turbine flowmeter: The displayed flow rate does not match the actual flow rate: the reason may be due to incorrect instrument coefficient settings, sensor failures, or fluid conditions in the pipeline that do not meet the requirements. The solution is to recalibrate the instrument coefficients, check if the sensor circuits and turbine blades are intact, and improve the fluid condition. No traffic display: It may be due to power failure, s
