Abstract
The present invention provides a flow meter whereby movement of fluid causes screw spindles or other movable elements to rotate and generate electronic pulses. The invention compensates for non-linearity in the relationship between the flow rate and the number of pulses, occurring particularly at low flow rates, by providing a device in the form of a transducer which assigns volume a value to each pules, which volume values are accumulated such that when certain predetermined value is exceeded a transducer generates a counter signal. Thus, the present invention enables compensation for non-linearity to be made and pulses output corresponding to a standard unit of volume.
