Droplet Borehole Water Level Meter
Droplet can be used to monitor water levels in boreholes. It is a practical, affordable, accurate, and precise meter. It is easier to use as an alternative to existing groundwater table monitoring systems that require the use of a graduated tape measure.
Droplet can measure water level instantly, and the same data acquisition unit can be conveniently used at multiple borehole locations. The affordability and flexibility of Droplet allow it to remain in the borehole for as long as required, thereby enabling continuous data acquisition.
Provided that the elevation of the borehole bottom is known, Droplet provides an accurate and reliable estimation of groundwater table elevation. Barometric pressure correction is inherently performed by the application. Data streaming to any smart device based on Bluetooth connection protocols has never been easier than with Droplet.
Droplet is lowered into a cased borehole with known depth and connected to a portable, 9 V battery-powered data acquisition unit. The system is powered on and paired via Bluetooth with an Android-based smartphone or tablet using the freely available GeoAnts Droplet application. After this simple setup, real-time groundwater table data can be monitored directly via your device.
