ABSTRACT:
Linear sensing apparatus for a positive displacement meter includes relative to each piston of the meter, an elongated rectangular member rigidly attached at one end to the top face of its associated piston, and carrying at its other end a multiwindowed member that reciprocates back and forth with movement of the piston for alternately interrupting detectable energy flowing between energy transmitting and detecting devices, the detecting device converting the detected energy into alternating electrical signals analogous to the volume of fluid passed through the meter, whereafter the signals are processed via a microprocessor for obtaining the actual volume and/or price of the fluid passed through the meter over a given period of time.
