ABSTRACT:
A pump leak monitor for use with a peristaltic pump comprises a pump housing and a pair of electrical contacts disposed along a bottom end of the pump housing. The electrical contacts are located such that the contacts are immersed in fluid when the pump is leaking. The fluid conducts electricity across the contacts and thereby closes an electrical circuit for providing an indication that a leak has been detected. By measuring an electrical parameter in the circuit, the pump leak monitor is capable of measuring the conductivity of the fluid in the pump housing. As a result, the pump leak monitor is capable of differentiating between different types of fluid.
