Abstract

The normal contact type liquid measurement devices have some drawbacks since they have potential damage due to the sensor fouling or corrosion since those are continuously exposed to the liquid. Especially flash flood may cause the damage of liquid level sensor. So that, it is important to design a non-contact device for liquid level measurement in order to avoid this constrain. Distance can be measured without contact such as laser, ultrasonic and radar. In this research, ultrasonic sensor is used to provide non-contact feature of the device since it is low cost and uses ultra-sound waves rather than light. This vital sensing device is able to sense uneven surfaces, liquids, clear objects, and objects in dirty environments. This paper discussed the measurement of liquid level in a tank as well as storing historical data.

Highlights

This project is aimed at designing a device that can provide non-contact level measurement of a liquid tank
It will reduce the potential damage of device due to the sensor fouling or corrosion while it continuously exposed to the liquid
The research of the distance measurement system that consider the high ratio of ability and decreased value has ended at ultrasonic sensor

Summary

Introduction

This project is aimed at designing a device that can provide non-contact level measurement of a liquid tank. The meaning of non-contact here is that the device, which is used, for liquid level measurement is not put directly in liquid It will reduce the potential damage of device due to the sensor fouling or corrosion while it continuously exposed to the liquid. To provide non-contact feature of the device, ultrasonic sensor is used since it uses sound waves rather than light. It has different sensing capability like as uneven surfaces, liquids, clear objects, and objects in dirty environments. Distance can be measured various way like as laser and radar. The research of the distance measurement system that consider the high ratio of ability and decreased value has ended at ultrasonic sensor
