Application

Tips: What is the role of magnetic water flow meter composition?
The electromagnetic flowmeter is mainly composed of two main parts: the sensor and the converter, of which the sensor includes flange, lining, electrode, measuring tube, excitation coil, sensor shell and other parts; the converter includes internal circuit board and converter shell and other parts.
-
Converter: Provide stable excitation current for the sensor, and at the same time amplify the induction potential obtained through the sensor into a standard electric signal or frequency signal, and at the same time display the real time signal. At the same time, it amplifies the induced electromotive force obtained through the sensor and converts it into standard electric signal or frequency signal, and at the same time, it displays the real-time flow rate and parameters. It is used for flow display, control and adjustment.
-
Flange: Double side flanges for magnetic flow meters Used to connect with process pipeline.
-
Lining: a complete layer of electrical insulation and corrosion-resistant material on the inside of the measuring pipe and the sealing surface of the flange.
material.
-
Electrodes: A pair of electrodes is installed on the wall of the measuring pipe perpendicular to the magnetic force line to detect the flow signal.
The electrode material can be selected according to the corrosive properties of the measured medium. Another 1~2 grounding electrodes are installed for flow signal measurement.
Another 1~2 grounding electrode is installed for flow signal measurement of grounding and anti-interference.
-
Measuring tube: Measuring tube flowing through the measured medium. Measuring tube by the non-magnetic stainless steel and
flange welded together and lined with an insulating liner.
-
Excitation coil: The measuring tube is equipped with a set of coils at the top and bottom of the outer side of the measuring tube to generate the working magnetic field.
-
Shell: Both play a role in protecting the instrument and sealing.
