The intelligent flow sensors of the induQ® series operate according to the induction principle: the measuring pipe is surrounded by a magnetic field (B). If an electrically conductive medium with the flow rate to be determined (Q) flows through the measuring pipe and thus enters the magnetic field at a right angle, a charge (U) is induced into the medium which is proportionate to the mean flow velocity and tapped by two electrodes. For an output signal which is proportionate to the flow rate, there are two versions available:

The pulse rate can be configured at the factory depending on the type.
