1. What are the flowmeter products with similar accuracy to electromagnetic flowmeters?
The flowmeter products with similar accuracy to electromagnetic flowmeters mainly include Coriolis mass flowmeter, high-precision pipe section ultrasonic flowmeter, and high-precision turbine flowmeter.
1. Coriolis mass flowmeter 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. 3. Representative products include Siemens FUS series and Xingao Technology XUF-P series (accuracy ± 0.5% - ± 1.0%). 4. It is suitable for trade handover or high-precision process control of clean liquids (such as water, oil, solvents), and has higher cost-effectiveness in large-diameter scenarios.
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 to electromagnetic flow meters. 2. It has fast response speed, excellent repeatability (± 0.1%), and low overall cost.
