EPD Electromagnetic Flow Meter, Water Flow Meter (OIML)

The working principle of the electromagnetic flow meter is based on the Faraday law of electromagnetic induction. When the conducting liquid flows in the orthogonal direction of the magnetic line direction, it will cut the magnetic lines and generate induced voltage, which shows linear relationship with the flowing speed. Thus, the fluidic volume flow can be calculated. 

EPD electromagnetic flow meter is mainly composed of the sensor and transmitter. The measuring tube of the sensor is equipped with the excitation coils upward and downward. The transmitter supplies the excitation current, which generates the magnetic field which goes through the measuring tube once it is powered on. A pair of induction electrodes installed on the inner side of the measuring tube comes in contact with the liquid to guide the induced voltage to the sensor.

。Measurement is virtually independent of density, viscosity, temperature, pressure and conductivity.
。Two measuring points inside tube and no moving parts to prevent pressure losses and pipe blockage.
。Electric conductive liquid and fluids with low solid contents can also be measured.
。Simple piping design: straight zone of the pipe for installation requests upstream 5D and downstream 2D.
。With self diagnosis function to check magnetizing signal, empty pipe and contaminated electrode.
