Principle of Operation
A controlled magnetic field is applied to the metering tube by way of externally mounted coils. The conductive fluid flowing through the magnetic field generates a voltage at the sense electrodes that is proportional to the velocity of the fluid. Grounding electrodes detect any ambient noise that may be present. Dual signal processing of the signals from the sense and ground electrodes result in noise cancellation resulting in higher accuracy across a greater flow range. The processed signal is then converted to volumetric flow.
