Municipal pump monitor demonstration project. Final report. IDWR Contract No. 89-03-21-103-12 Item Info

This report covers the demonstration of electronic pump efficiency monitoring demonstrated on two municipal water supply wells in Idaho. One of the wells monitored was a variable speed pump and the other was a fixed speed pump. Both of the monitoring systems were operated for a five month period during the summer and fall of 1989. The efficiency data collected showed that the fixed speed pump was operated at an average energy efficiency of 65 percent. The energy efficiency of the variable speed pump ranged from 9 to 65 percent. The variable speed pump was operated by the municipal water department to maintain a constant pressure in the water supply system. The wire to water energy efficiency of the pump was closely related to pump speed and consequently the discharge rate. The efficiency monitors demonstrated were constructed from readily available components, and can be assembled by local electronic hobbyists. The system consists of HP41CX programmable calculator, CMT-200 HP/IL interface, a signal conditioning unit an various sensors. In addition to energy efficiency, the system tracks discharge, pressure, water level, input energy, pump speed and production costs.
