ABSTRACT:
A roller pump having one or more hoses is combined with a control system including a potentiometer for controlling the speed of the pump motor. A manually settable control provides an output corresponding to the diameter of the hose, and a further control provides an output corresponding to the number of hoses. An electronic circuit connected to receive the outputs of the controls, provides an output signal corresponding to the flow rate of the pump. This signal is applied to an indicator, so that an operator may adjust the speed of the pump to obtain a desired flow rate.
