Abstract
A volume-based, rather than time-based, system for dispensing fluid incorporates a microprocessor-based controller, software, pump, and positive displacement flow meter. The volume being pumped and the time it takes to pump that volume is calculated and tracked by the software, giving a flow rate. This rate is then tracked by the software for any changes. Any conditional changes that occur, affecting this rate, are tracked, and if the rate becomes too excessive outside of the normal rate established at initial calibration, then an alarm or other indication is provided to the operator.
