Electromagnetic flowmeter straight pipe requirements?

The company adopts the all-intelligent electromagnetic flowmeter developed by domestic and foreign advanced technology, and its all-Chinese electromagnetic converter core uses a high-speed professional processor.The calculation speed is very fast, the accuracy is high, and the measurement performance is reliable.The sensor adopts non-uniform magnetic field technology and special magnetic circuit structure. The magnetic field is stable and reliable, and the volume is greatly reduced, which eliminates repetition and makes the flowmeter small and flowable. The measurement results are consistent with fluid pressure, temperature, density, viscosity and other physical Parameter independent, it is a true volume flow meter.

Straight pipe length requirements In order to obtain normal measurement accuracy, there must be a certain length of straight pipe upstream of the electromagnetic flow sensor, but its length is comparable to most other flow meters.After 90° elbow, T-shaped pipe, concentric reducer, and fully open gate valve, it is generally considered to be a straight pipe section that is 5 times the diameter (5d) from the centerline of the electrode (not the connection surface of the sensor inlet end). Valves with different openings require 10d; the downstream straight pipe section is (2~3)d.(2) The installation of negative pressure piping system The fluoroplastic lined sensor must be carefully applied to the negative pressure piping system; the positive pressure piping system should prevent negative pressure, such as the piping system where the liquid temperature is higher than room temperature, close the upstream and downstream shut-off valves of the sensor to stop After running, the fluid cooling and contraction will form a negative pressure, and a negative pressure prevention valve should be installed near the sensor.
