Abstract
Described is a method for regulating a volume of liquid delivered by a peristaltic pump and a peristaltic pump system that can be used to perform the method. The method includes sensing an ambient temperature of the peristaltic pump. The peristaltic pump includes a pump motor. At least one of a motor speed and a motor operation duration is determined from the sensed temperature, a selected volume of liquid to be delivered and a predetermined correspondence of the motor speed to ambient temperature. The pump motor is operated at the determined motor speed or for the determined motor operation duration to deliver the selected volume of liquid from the peristaltic pump.
