The electromagnetic flow meter is installed in the water circuit of the HM 500 trainer. It operates according to Faraday’s Law of Induction. When a conductor is moved in a magnetic field, a voltage is induced in the conductor. The flowing fluid represents the moving conductor. The magnetic field is generated by a switched direct current of alternating polarity. The induced voltage is tapped at two insulated electrodes. The magnitude of this induced voltage is proportional to the flow rate. A display indicates the flow rate. The necessary connections are provided so that the pressure loss can be determined with the HM 500.
