Water Level Monitoring

Water level loggers are used for monitoring changing water levels in a wide range of applications including streams, lakes, wetlands, tidal areas and groundwater. The loggers are either deployed in existing wells or stilling wells installed specifically for deploying the loggers. An extra logger is typically deployed in the air to record changes in the barometric pressure to compensate the water pressure readings for optimal accuracy. One barometric logger or weather station can be used to compensate all of the water level loggers in that area. HOBOware Pro includes a Barometric Compensation Assistant for easy and accurate barometric compensation.

Deployment Tips:
• For hanging water level loggers in a well, be sure to use wire that won't stretch or kink.
• For the best accuracy, deploy barometric pressure loggers where the temperature does not change that much, such as in the air space in a well below ground level.
• Be sure that the wells with loggers in them have vent holes to the atmosphere, so they all are exposed to the same barometric pressure above the water.
