Abstract

Method and system for measured dispending of a liquid to a target reservoir. An oval gear flow meter provides two pulses from different magnets. A pipe subsystem allows liquid from an above-ground reservoir measured through the oval gear flow meter to be controllably dispensed using a controllable valve. A processor module, upon receipt of a start-signal, opens the controllable valve and, until receipt of a stop-signal, computes a volume of the liquid dispensed by the system into the target reservoir by counting the pulses as a first and second counts. An adjustable volume-per-count value is computed with the count(s) to obtain the volume of liquid dispensed. The processor generates an error when a difference between the two counts is greater than a predetermined threshold set considering a target precision setting for the dispensing system.
