Patent attributes
The present invention provides a groundwater monitoring system and method. The system in one aspect uses sound-based distance measurement techniques to measure groundwater level with one transducer generating an acoustic burst and another receiving it. At least one sonic transducer is installed in each of a processor-based controller and traveling probe. The system may use an accelerometer and the pressure sensor installed in the probe to measure groundwater thickness. While the probe moves upward or downward in the groundwater, water properties measured by sensors installed on the probe and corresponding depths of the measuring spots to the groundwater surface level measured by the pressure sensor are recorded. The system measures and saves data, including groundwater level, groundwater thickness, and a depth-related profile of water properties. In certain embodiments, the probe includes a microprocessor operable to control the transducer and sensors mounted thereto and effect two-way communication with the controller.
