The Eno Scientific WS2100 Flow Meter Kit combines all the instrumentation needed to perform a complete well draw down test. Starting with our popular sonic water level meter, the Well Sounder 2010 PRO, with its built-in data logger and USB computer connectivity. Add the new Eno Scientific WS131 Flow Meter with a variety of housing sizes and you are ready to start drawdown testing.
Our flow sensors come with Well Sounder compatible cables which eliminate the hassles of wiring multiconductor flow meters and supplying external power. The WS131 Flow Meter simply plugs into the Well Sounder 2010 PRO and it is ready to go. The Well Sounder's proprietary self calibration routine makes the process simple.
Complete groundwater monitoring begins by turning on the Well Sounder 2010 PRO, enabling the data logger and performing your drawdown test. The Well Sounder will record the static level and the pumped volume at an interval of your choosing between 1 second and 60 minutes for the duration of your test. When the test is complete, connect the Well Sounder 2010 PRO to your computer with the included USB cable. A window pops up with the data file which can be imported into Excel and graphed or printed and simply attached to your report.
