1. What are the flow meter products with similar accuracy to electromagnetic flow meters?
Flow meter products with similar accuracy to electromagnetic flow meters mainly include Coriolis mass flow meters, high-precision pipe section ultrasonic flow meters, and high-precision turbine flow meters.
1. Coriolis mass flow meters.
The accuracy range is ± 0.05% - ± 0.2%, and some high-end models can achieve an accuracy of ± 0.05%, which matches the conventional accuracy range of electromagnetic flow meters. 2. It can directly measure mass flow without being affected by factors such as temperature, pressure, density, viscosity, etc., and can also output density and temperature parameters at the same time, with a large range ratio. 3. Representative products include Emerson high-precision series and Xingao Technology XMC series (optional ± 0.05% accuracy). 4. It is suitable for trade handover of crude oil, finished oil, chemical raw materials, liquefied gases, as well as accurate proportioning and mass balance scenarios in scientific research. 5. The limitation is that large-diameter products have high cost and are sensitive to vibration and two-phase flow, requiring regular zero point testing. Calibration.2. High precision pipe section ultrasonic flowmeter 1 The accuracy range is ± 0.5% - ± 1.0%, which meets the conventional accuracy requirements of electromagnetic flow meters. 2. It has the characteristics of zero pressure loss and no moving parts, and can measure non-conductive liquids (such as oil), supporting bidirectional measurement. Lower.
III. High precision turbine flowmeter 1 The accuracy range is ± 0.5% - ± 1.0%, and some high-end models can reach ± 0.2%. The accuracy is comparable

2. Does the turbine gas flowmeter belong to mandatory testing equipment?
The turbine gas flowmeter belongs to mandatory calibration equipment, 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 doe
