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.

Meter

A modular utility meter, for example, a water meter, is provided which comprises a meter base and a meter head. The output signal from a transducer in the meter base is processed in the meter head to calculate the utility supply. The processing includes linearization of the signal calibration data stored in the meter base. Therefore, any meter head may be combined with a meter base containing any different type of transducer.

Modular utility meter

A modular utility meter (), for example, a water meter, is provided which comprises a meter base () and a meter head (). The output signal from a transducer in the meter base () it processed in the meter head () to calculate the utility supply. The processing includes linearization of the signal using calibration data stored in the meter base (). Therefore, any meter head may be combined with a meter base containing any different type of transducer.
