The Pump Station Calculator from FlowWorks uses simple pump on/off signals to determine pump station inflow and pump performance. The signals can be collected from data loggers or SCADA systems, and the program is designed to handle a variety of pump station configurations. It lets users estimate pump station inflow based on pumped wet well volume and pump start/stop times. The inflow signal will be similar to having a flowmeter installed at the inlet of the pump station. The estimated inflow signal can be used for I&I studies, capacity assessment for capital planning, and computer model calibration. The ability to make ongoing estimates of pumping rates for each pump in operation allows operators and engineers to determine if the pumps installed are performing as designed. Alarming can be set up to inform users of pumps that drop below a predetermined performance point. 888/400-3288; www.flowworks.com.
