PCE-VMI 20 Electromagnetic Flow MeterFlow Meter to measure all electrically conductive liquids \/ without any moving part \/ without mechanical wear \/ no additional pressure drop The PCE-VMI Electromagnetic Flow Meter can be used in the construction of machines and plants thanks to its compact design. The PCE-VMI Electromagnetic Flow Meter is used where flow meters with moving parts such as vane flow meters cannot be used due to the dirt. The PCE-VMI Electromagnetic Flow Meter is used for the continuous flow measurement or the dosage of electrically conductive liquids with a minimum conductivity of 50 μS\/cm. The PCE-VMI Electromagnetic Flow Meter operates according to the electromagnetic induction principle: The measurement tube is locate on a magnetic field. If a conductive medium flows through the measurement tube perpendicular to the magnetic field, a strength proportional to the mean flow velocity is induced to the medium and it is captured by two electrodes. A frequency proportional to the flow is emitted as signal output.
