Long Life 50mm Water Oil Electromagnetic Flow Metre For Liquid Nitrogen
HKLD type intelligent electromagnetic flowmeter is a fully intelligent electromagnetic flowmeter developed by our company using the most advanced technology at home and abroad. Its electromagnetic converter core adopts high-speed central processing unit. The calculation speed is very fast, the precision is high, and the measurement performance is reliable.
Features
1. There are no flowing and blocked flow parts in the pipeline of the 50mm water oil electromagnetic flow meter, and there is almost no additional pressure loss in the measurement.
2. The measurement result of the 50mm water oil electromagnetic flow meter has nothing to do with physical parameters, such as flow distribution, fluid pressure, temperature, density and viscosity.
3. The electromagnetic flowmeter uses a fast, high-precision 16-bit embedded processor to enhance the measurement stability.
4. The 50mm water oil electromagnetic flow meter has anti-interference and high reliability, and the measurement range is up to 150: 1.
5. The flowmeter adopts ultra-low EMI switch, and the power supply voltage range is wide.

Precautions
1. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields, so as to avoid the magnetic field affecting the working magnetic field of the sensor and the flow signal.
2. should be installed in a dry and ventilated place, to avoid sun and rain, the ambient temperature should be -20 ~ +60 ° C, relative humidity is less than 85%.
3. There should be plenty of space around the flowmeter for easy installation and maintenance.
Installation requirements
The measurement principle of the electromagnetic flowmeter is that it does not depend on the flow characteristics. If there is a certain turbulence and vortex inside the pipeline, it will be generated in the non-measurement zone (such as elbow, tangential current limit or half-opening shut-off valve upstream). Measurement is irrelevant. If steady-state eddy currents in the measurement zone affect the stability of the measurement and the accuracy of the measurement, then some measures should be taken to stabilize the flow rate distribution:
A. Increase the length of the straight pipe before and after.
B. Using a flow stabilizer.
C. Reduce a section of the measuring point.
