Note that in practical applications, appropriate models and technical parameters should be selected based on specific needs.

Kudaden Electromagnetic Flow Meter

Electromagnetic flow meter yana da electrically insulated pipe, a pair of electrodes placed opposite to each other, da kuma magnetic coils positioned around the pipe for generating the magnetic field. Electrically insulated pipe, typically made from non-conductive materials such as fiberglass, carries the liquid whose flow rate needs to be measured.

Electrically Insulated Pipe: Wannan pipe yana da electrically insulating materials don ensure that the liquid passing through it can be accurately measured without interference from external electrical influences.

Electrodes: Two electrodes are mounted opposite each other on the pipe. Their function is to detect the induced voltage generated as the liquid flows through the magnetic field. These electrodes come into direct contact with the flowing liquid and transmit the detected voltage signals to a converter for processing.

Magnetic Coils: Magnetic coils are wrapped around the pipe. When current passes through these coils, they generate a magnetic field perpendicular to the direction of liquid flow. This magnetic field is crucial for inducing the voltage according to Faraday's Law of electromagnetic induction, which is proportional to the velocity of the fluid.

An electromagnet is positioned around an insulated pipe, generating a magnetic field in its vicinity. This setup is analogous to a conductor in motion within a magnetic field. As the liquid flows through the pipe, a voltage is induced across the coil, which can be expressed as follows.

v represents the velocity of the conductor (equivalent to the flow velocity), measured in meters per second (m/s).

l is the length of the conductor, which is equal to the diameter of the pipe, measured in meters (m).

Bdenotes the magnetic flux density, with the unit webers per square meter (wb/m²).

When the magnetic field around the pipe stays constant, the induced voltage is directly proportional to the velocity of the fluid.

Fadada Electromagnetic Flow Meters

• The output voltage of an electromagnetic flow meter is proportional to the liquid's flow rate.

• The output remains unaffected by variations in liquid properties such as viscosity, pressure, and temperature.

• These flow meters are capable of measuring the flow of slurries and greasy substances, and can handle corrosive fluids.

• They can function as bidirectional meters.

• Electromagnetic flow meters are also able to measure extremely low flow rates.
