1. 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 practical 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 re

2. What is the working principle of gas turbine flowmeter utilization? What are its characteristics? The working principle of gas turbine flowmeter: The gas turbine flowmeter uses a turbine for measurement. It first converts the flow velocity into the rotational speed of the turbine, and then converts the rotational speed into an electrical signal proportional to the flow rate. This type of flowmeter is used to detect instantaneous flow and total cumulative flow, and its output signal is frequency, which is easy to digitize. The induction coil and permanent magnet in the picture are fixed together on the housing. When the ferromagnetic turbine blades pass through the magnet, the magnetic resistance of the magnetic circuit changes, thereby generating an induction signal. The signal is amplified and shaped by an amplifier and sent to a counter or frequency meter to display the total accumulated flow rate. Simultaneously, the pulse frequency is converted from frequency to voltage to indicate instantaneous flow rate. The rotational speed of the impeller is proportional to the flow rate, and the rotational speed of the impeller is proportional to the total amount of flow. The output of the turbine flowmeter is a frequency modulated signal, which not only improves the anti-interference ability of the detection circuit, but also simplifies the flow detection system. Its range ratio can reach 10:1, and the accu
