A corona-discharge type gas flow meter includes a discharge electrode, and a split collecting electrode, the collecting electrodes are connected to input amplifiers which act as current-to-voltage converters receiving a reference signal from an integrator acting to integrate the sum of the outputs of the input amplifiers. The output of the integrator is used to control an EHT supply for the discharge. An output amplifier provides a flow signal by running the signal from one input amplifier, from a variable offset nulling signal derived via an amplifier from the integrator and a fixed offset nulling signal from a potentiometer.
