Abstract
A flow meter having electrical signal outputs and a digital display is described. A transducer uses a magnet inside the flow meter to position a ball on a resistor bar and a contact bar and, thus, generate a position signal. The position signal provides an accurate electrical indication of flow to the circuitry driving the display.
