Design, Development, and Prototyping of an Intelligent Volumetric Measurement System for Water Containers

ABSTRACT: The aim of this thesis is to build an intelligent water volume measurement device that calculates the water volume for any shape of tank precisely by measuring the water level with an ultrasonic sensor and using a look-up-table to calculate the volume. It generates alarm signals at any desired volume. For any shape of tank, the look-up-table is entered to the processors memory using five buttons, and LCD display. The prototype gets power from mains through a USB socket even if it is not connected to a computer. The system is designed at a system-level using basic building blocks for Arduino from a Arduino Uno processor board, a keypad + LCD display shield with a LED, an ultrasonic HC-SR04 sensor unit, and an external buzzer. The prototype is tested successfully for a horizontally placed cylindrical container to have maximum 1.3%, average 0.7% error on distance and percent volume measurements.
