Bamomatic is a flowmeter based on the principle of electromagnetic induction to measure flow rate on electrically conductive liquids ( > 20 μS/cm). It is perfectly suited for dosing or totalizing liquids. Each instrument is calibrated on a bench test at ± 5/1000 pulses of water at 23 °C. Density of the liquid, its temperature or its pressure has no influence on the measurement; No moving parts in this flow-meter: it ensures operating without mechanical wear.
The measuring principle is based on Faraday’s law (a): In an electromagnetic flow-meter, the liquid section is in a magnetic field created by solenoid coils. Electrode sensors are located on a plane, perpendicular to the magnetic field, in contact with the (conductive) liquid, allowing 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).
(a): According to Faraday’s law, electromagnetism principle, the voltage induced in a moving conductor through a magnetic field, is directly proportional to the conductor speed.
