Water Level Logging
October 1, 2002
The Model WL15 Water Level Logger measures and records ground water, surface water level in boreholes, flumes and weirs. The WL15 data logger has a 1 7¿inch (fits inside a 2-inch well) diameter stainless steel housing. In a borehole application, the data logger cap holds the WL15 at the top of the well and allows use of a borehole locking cap for security. The water level sensor is housed in 3¿inch stainless steel (fits inside 1-inch wells). Six pressure ranges meet a wide range of applications. The 0- to 2-foot range is well suited for shallow ground water to surface water relationship studies. Global Water Instrumentation Inc.
