Computing Apparatus for Real-Time Groundwater Level Measurement and Analysis

A system for determining vessel fill percentages using sensor technologies. The system receives a sensor type selection through a graphical user interface at a client device, displays a request for vessel configuration information based on the selection, and configures a lookup table using the received configuration data. When measurement data is received from the sensor device, the system determines the vessel's fill percentage by applying the lookup table to transform raw sensor readings into accurate fill levels, then displays the fill percentage with a vessel identifier. The system accommodates various vessel shapes, dimensions, and configuration parameters including strapping charts, while supporting multiple measurement data types such as distance, pressure, temperature, voltage, current, and magnetic flux. This unified framework enables standardized monitoring across vessel types through a single interface.
