Abstract
A scaled quadrature pulse output signal is generated for representing direction and volume in predetermined increments of the flow of a liquid or a gas through a meter. An unscaled pulse signal is received from a meter. A scaling factor is applied to each unscaled pulse signal for accurately representing an increment of volume. The increments are sequentially added or subtracted to/from one another (depending upon flow direction) and a scaled quadrature output signal is provided for indicating the direction of flow and the volume of flow in predetermined increments.
