How Does an Electromagnetic Water Flow Meter Work?

An electromagnetic water flow meter operates on the principle of electromagnetic induction. As the conductive fluid flows through the pipe, it cuts across the magnetic field created by the sensor. According to Faraday's law, this movement induces a voltage in the fluid, which is sensed by the electrodes. By measuring the induced voltage, the flow meter can determine the flow velocity and calculate the volumetric or mass flow rate.

The magnetic field strength, generated by the sensor, plays a crucial role in the accuracy of the measurement. The electrode arrangement ensures that the voltage is measured accurately across the fluid's cross-sectional area. Sophisticated algorithms and signal processing techniques further enhance the accuracy and stability of the measurements.

Classification of Electromagnetic Water Flow Meter

1.  electromagnetic water flow meter is classified according to the excitation mode, there are DC, AC, rectangular wave excitation.

2. According to the assembly form for classification, there are split type and one body type. Currently more commonly used in the petrochemical industry is a body type, but when the site environment is more severe, such as underground, there are strong vibration of the pipeline, or the converter needs to be installed in the inspector more accessible occasions more need to split the type of magnetic inductive flow meter.

3. Classified according to the connection with the pipeline, there are flange type, insertion type, clamping type and so on. Flange connection is the traditional connection and also the most commonly used connection in the petrochemical industry. However, in some relatively thick pipeline, or the installation of harsh conditions, the insertion type flowmeter is smaller and more conducive to maintenance is more suitable.

4. According to whether the electrode and the measured liquid contact classification, there are contact and non-contact type. At present, the petrochemical industry commonly used or contact type electromagnetic water flow meter.
