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
