Pumpstation Datalogger (2 Pumps)
Multiple Pump Monitoring Low Power Wet Well Levels and Optional Outflow are Recorded
Pump Station Wet Well inflow and outflow analysis
The PD-2 Pump Station Datalogging System is used to capture information pertaining to the flow in and out of a pump station. The flow into the station is calculated by using the wet well level and the wet well volume. With the use of a Data Dolphin datalogger, the PD-2 captures and records the contact closure of a relay to mark a pump start or stop event. Upon a relay’s contact closure or release, the PD-2’s datalogger will record the date, time, wet well level and pump status. Wet well levels (and optional outflow) are also recorded at regular timed intervals. This data is later processed for pump runtime and flow monitoring analysis.
