Claim 0:
1. A method for regulating a volume of liquid delivered by a peristaltic pump, the method comprising:
sensing an ambient temperature of a peristaltic pump having a pump motor;
determining one of a motor speed and a motor operation duration for the pump motor based on the sensed ambient temperature, a selected volume of liquid to deliver and a predetermined correspondence of the motor speed to the ambient temperature to produce a volumetric flow rate from the peristaltic pump, wherein the predetermined correspondence of the motor speed to the ambient temperature comprises previously acquired data indicating the motor speed used to produce the volumetric flow rate as a function of ambient temperature and as a function of a storage condition of the peristaltic pump; and
operating the pump motor at the determined motor speed or motor operation duration to deliver the selected volume of liquid from the peristaltic pump.
