Kobold’s MIS magnetic inductive flowmeter was specially developed for measuring the medium-sized flow of conductive liquids in pipes. Operated by electromagnetic measurement, a voltage is induced in a conductor moving through a magnetic field. The electrically conductive measuring agent acts as the moved conductor. The voltage induced in the measuring agent is proportional to the flow velocity and is thus a value of the volumetric flow. The flowing media must have a minimum conductivity. The induced voltage is picked up by two sensing electrodes in contact with the measuring agent and is sent to the measuring amplifier. The flow rate is calculated in the cross-sectional area of the pipe. The measurement is not dependent on the process liquid and its material properties, such as density, viscosity and temperature. Two given outputs can be set to either: switch, analogue or frequency. A dosing function can also be selected.
