ABSTRACT:
A positive displacement meter for measuring the volume of liquid dispensed over a given period of time includes at least one pair of pistons moving in counter opposition to one another within a pair of cylinders, an acoustical transducer located through a side wall of one of the cylinders, for transmitting and receiving acoustical pulses along a folded acoustical pathway, a first portion of which is transverse to the face of the piston, and a second portion of which is parallel to the axis of movement of the piston, via a wedge-shaped reflector mounted on the inside wall of the cylinder directly opposite from the acoustical transducer for so reflecting transmitted and reflected acoustical waves between the transducer and face of the piston under measurement, whereby changes in the position of the piston are detected over successive measuring periods for determining each full stroke thereof, representative of a given amount of fluid or liquid being dispensed from the meter, which volume portions are accumulated over a given dispensing period for determining the total volume of fluid dispensed.
