Inductive Magnetic Dn 400mm Electromagnetic Flow Meter For
Agricultural
Electromagnetic Flow Meters manage critical flow applications to
improve accuracy, decrease system maintenance and meet the demands
of challenging liquid conditions. This volumetric flow meter does
not have any moving parts and is ideal for wastewater applications
or any dirty liquid that is conductive or water-based.
A magnetic flow meter (mag flowmeter) is a volumetric flow meter
which does not have any moving parts and is ideal for wastewater
applications or any dirty liquid which is conductive or water
based. Magnetic flowmeters will generally not work with
hydrocarbons, distilled water and many non-aqueous solutions).
Magnetic flowmeters are also ideal for applications where low
pressure drop and low maintenance are required.
Principle of Operation
Faraday's Law The operation of a magnetic flowmeter or mag meter is
based upon Faraday's Law, which states that the voltage induced
across any conductor as it moves at right angles through a magnetic
field is proportional to the velocity of that conductor.
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.
