    Operating instructions FlowGuard® FT410 1. General information 1.1 Description Measuring principle The FlowGuard® FT410 flow meter is a measuring device based on Faraday's law of electromagnetic induction. A voltage is induced when a conductive liquid flows through the magnetic field of the device. This voltage is recorded by two electrodes that are in direct contact with the liquid and evaluated by the electronics.
