Bamo BAMOMATIC Electromagnetic Flow Meter  is a flow meter based on the principle of electromagnetic induction to measure flow-rate on electrically conductive liquids ( > 20 μS/cm). They are perfectly suited for dosing or totalizing liquids. Each instrument is calibrated on a bench test at ± 5 pulses for 1000 pulses (Water at 20 ° C). Density of the liquid, its temperature or its pressure have no influence on the measurement; No moving parts in this flow-meter: it ensures operatings without mechanical wear.

The measuring principle is based on Faraday’s law. In an electromagnetic flow-meter, the liquid section is in a magnetic field created by solenoid coils. Electrode sensors are on plane perpendicular to this field, in contact with the (conductive) liquid and allow measurement of the generated voltage. This voltage is directly proportional to the fluid velocity and therefore to the flow rate (for a constant flow section).
