ABSTRACT:
In a system for controlling fluid flow from a reservoir to a patient, a first signal representative of reservoir weight and a second signal representative of desired weight are compared digitally to generate a signal representative of their dissimilarity. An analog strain gauge may be used together with an analog-to-digital converter for generating the reservoir weight signal.
