Abstract

A microprocessor based flow meter establishes a series of pump on and off time intervals. Using previously entered flow rate information, the meter establishes quantities of flow during each pumping cycle or totals for predetermined time intervals such as days or weeks. Quantities of flow can be displayed on a per cycle basis or can be accumulated based on predetermined elapsed time intervals such as days or weeks.
