Description

The Water Level Logger, WL15 provides a datalogger with a submersible pressure transducer for remote monitoring and recording of water level, flow, and pressure data. This highly reliable and accurate water logger records 24,400 readings and is programmable from one reading per second to one reading per day.  Ranges of 0-3', 0-15', 0-30', 0-60', 0-120' and 0-250' are available.  A 25' cable is standard, and  optional cable lengths are available up to 500' (WLEXC).
