System for Measuring a Liquid Surface Level within a Storage Tank

摘要

A measuring system places a plurality of sensor arrays in a lateral enclosure, the sensors being able to measure movement of magnetic floats from which a liquid level can be calculated. The plurality of sensor arrays is serially positioned in the lateral enclosure in order to enable monitoring of the entire lateral enclosure. The plurality of sensor arrays uses a circuit board with a plurality of a Hall-Effect sensors and a microcontroller to detect the magnetic floats. The circuit boards are also provided with male and female interconnectors to allow an arbitrary sensor array to be connected to an adjacent sensor array; through these connections each of the plurality of sensor arrays is grouped and in combination able to monitor the entire area of the lateral enclosure. A segmented construction for the lateral enclosure is also possible, with each segment containing one of the sensor arrays.
