The top of the data logger will rest on the top of the well pipe A slip cap or a locking well cap can conceal the WL15 The cable length of the WL15 should be sized so the sensor will be positioned below the lowest expected water level which 1s not necessarily the bottom of the well The correct ca ble length is measured from the top of the data logger to the bottom of the sensor The sensor s measur ing range should be slightly larger than the expected total amount of change in water level To shorten the cable in a 2 diameter or larger well coil it around a 1 diameter stick or pipe and secure the cable at both ends with tie wraps or tape Warning Do not kink the cable this may damage the internal vent tube The WL15 can be adapted to larger or smaller well casings by using standard PVC pipe reducers and fittings or Global Water s Inside Well Option As factory programmed the WL15 records depth of water above the sensor If you want to use your WL1S5 to record depth to water readings follow the worksheet Calibrating Level Sensors for Depth to Water Readings Surface Water Installation The sensor may be submerged at the monitoring point and hung from its cable It is recommended to protect the sensor and datalogger inside a 4 PVC drainpipe that will act as a protective stilling well PVC schedule 40 or ABS sewer drainpipe is recommended PVC schedule 40 electrical conduit has UV protectors and pre formed sweeps or ben
