1. What types of flow meters and electromagnetic flow meters have comparable accuracy levels? Coriolis mass flow meters, high-precision turbine flow meters, multi sound simulated loss channel ultrasonic flow meters, and high-precision volumetric flow meters (elliptical gears, waist wheels, etc.) have accuracy levels that are basically equivalent to electromagnetic flow meters, and some high-precision models even have higher accuracy than electromagnetic flow meters. 1. Coriolis mass flow meters Accuracy parameters: The measurement error of high-precision industrial grade models can reach ± 0.05%~± 0.1%, while the error range of conventional models is ± 0.1%~± 0.5%, fully covering the commonly used accuracy range of electromagnetic flow meters from ± 0.2%~± 1%. Some specialized models have better accuracy
2. Adaptation features: Directly measure mass flow rate, not affected by the density, viscosity, and pressure fluctuations of the measured fluid, and can measure conductive and non-conductive fluids, but high concentration solid slurry will wear down the measuring tube and have certain requirements for the cleanliness of the medium.
2. High precision turbine flow trace sail meter 1 Precision parameters: The measurement error of the dedicated high-precision model can be as low as ± 0.1%, while the error range of the conventional industrial model is ± 0.2%~± 0.5%, which is consistent with the precision level of the high-precision model of the electromagnetic flowmeter.
2. Adaptation limitations: Only applicable to clean, low viscosity single-phase fluids (such as water, light finished oil), cannot measure impurities, high viscosity or multiphase fluids, and installation needs to meet the requirements

III. Multi channel ultrasonic flowmeter 1 Accuracy parameters: The measurement error of the segmented or inserted multi-channel model can reach ± 0.1%~± 0.2%, which is completely matched with the high-precision level accuracy of the electromagnetic flowmeter.
2. Adaptation features: It can measure conductive and non-conductive fluids, and adopts non-contact installation without direct contact with the medium, but requires the tested pipeline to be fully filled throughout the entire pipe. The presence of a large number of bubbles in the fluid will significantly reduce the measurement accuracy.
4. High precision volumetric flowmeter 1 Accuracy parameters: The measurement error of industrial grade high-precision elliptical gear and waist wheel flow meters can reach ± 0.05%~± 0.2%, which is comparable to the high-precision models of electromagnetic flow meters.
2. Adaptation features: Suitable for measuring high viscosity, clean single-phase fluids (such as lubricating oil and crude oil), the measurement accuracy is not affected by flow rate fluctuations, but cannot measure media containing solid particles. Changes in medium viscosity will cause slight interference to the measurement results.
