Abstract
A method of determining the inter-electrode or electrode-to-ground impedance or the filling state of an electromagnetic flow meter having flow sensing electrodes connected to an electrode signal amplifier, the method comprising applying a test input signal to the flow sensing electrodes via a connection through which an output flow measurement signal of the flow meter is transmitted from the amplifier, in a manner such that the output of the amplifier is indicative of the said impedance or the filling state.
