PCE-VMI electromagnetic flow transmitter flow transmitter to measure all electrically conductive liquids / without any moving part / without mechanical wear / no additional pressure drop
|
The PCE-VMI electromagnetic flow transmitter can be used in the construction of machines and plants thanks to its compact design. The PCE-VMI electromagnetic flow transmitter is used where flow transmitters with moving parts cannot be used, as for instance vane flow transmitters, due to the dirt. The PCE-VMI electromagnetic flow transmitter 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 transmitter operates according to the electromagnetic induction principle: The measurement tube is located 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. As signal output, a proportional frequency to the flow is emitted. In case you had any question on the electromagnetic flow transmitter, consult the technical data next or contact us: +44 ( 0 ) 2380 98703 0 . Our technicians and engineers will advise you on this ultrasonic flow transmitter or any other product our regulation and control systems, meters or scales of PCE Instruments.
