The data logger is not waterproof. It is water-resistant. This means that condensation, which can • build up inside the enclosure during humid conditions, should not affect the performance of the WL15. However, if the data logger is submerged in water, it will corrode the electronics and cause it to stop working properly. -
Page 15: Groundwater Installation
¼” hole should be drilled near the top of the pipe to allow air movement when the water goes up and down. A standard slip cap or a locking well cap can be used to secure the WL15. The pipe can also be adapted for a screw-on cap. -

For example, if you set your WL15 to record a reading every 20 minutes at fixed intervals and the process begins at 12:00:00, power will be applied to the level sensor immediately and a reading taken at 12:00:03. -
Page 24: Calibration
If performing a dry calibration, insert the sensor into your water pressure meter and set to full scale range of your WL15. If performing a wet calibration, insert level sensor to a water depth of at least 10% of full scale range. - Page 25 To revise calibration settings so that the graph will function cor- rectly, follow the worksheet Calibrating the Bar Graph to Higher or Lower Range in Appendix B*. *See Appendix B: Worksheets, pages 37 Global Water ● (800)876-1172 ● www.globalw.com Page 25...

Page 29: Chapter 4: Maintenance
This table is based on the worst-case scenario where the sensor is providing the maximum signal of 20mA. Temperature can also affect battery life. A WL15 in an environment that has a sustained temperature of 23° C will run 5% longer than a unit that has a sustained temperature of 0° C. -
Page 30: Calibration
Screw the cap on to the data logger housing, being careful not to pinch any of the wires. Calibration The level sensor’s calibration must be periodically verified. Global Water recommends checking the sen- sor’s calibration with a sounder or other measuring device once every 6 months. Sensor Screen Cleaning The screen on the end of the sensor must be periodically checked for clogging from mud and sludge. -
