ABSTRACT:
A fluidic oscillator liquid flow meter comprising a body having an inlet portion to receive a flow of liquid to be measured, an outlet portion, a main channel defining a flow path between the inlet and outlet, the flow path including feedback structure to induce oscillations in the flowing fluid, the oscillations being detected by detector comprising means to apply a magnetic field across the flow path and sensing electrodes to detect the resulting e.m.f., the electrodes being positioned such that they protrude from the body into the flow path. A meter having driving signal means, which applies an alternating driving signal to the sensing electrodes, is also disclosed.
