1. A flow meter comprising:
- control circuitry;
circuitry for storing a manually settable fluid flow rate parameter, coupled to the control circuitry;
time interval determination circuitry coupled to the control circuitry wherein in response to a received time interval defining signal, the determination circuitry establishes an indicium corresponding to the respective time interval and wherein the control circuitry combines the stored flow rate parameter with the indicium to establish a quantity of fluid delivered during the interval.

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.
