The capacitive sensors are widely used for liquid level measurement in different
applications, but the contact type capacitive sensors suffer from frequent maintenance and …

In many circumstances, the conventional ultrasonic liquid-level detection presents the
unreliable estimations due to the dynamically changed liquid level. In addition, there are …

This paper proposes an embedded system for measuring the water level on a river using a
camera. One of the main problems of using a camera in water-level measurement is that the …

We introduce a simple model for a gravity separator based on first principles. It can be used
for controller design to control the levels of oil, water, and the gas pressure as well as …

To prevent flooding from threatening people's lives and property, surveillance cameras have
been extensively installed along rivers to monitor the water level. In this study, an automatic …

Liquid level measurement is important requirement for building and industrial applications.
One of the most popular methods for level measurement is the capacitive sensor. Most of the …

This paper presents a capacitive liquid level sensor with four electrodes. By detecting the
level changes of liquid filled in a cylindrical vessel, not only liquid level information can be …

Ultrasonic based techniques have been explored to monitor emulsion layer and separation
of oil and water phases from their emulsions. Creation of oil and water emulsions is a …

This paper presents a virtual monitoring approach for a gravity separator. It is used to
separate the three phases oil, water and gas. The monitored variables are thereby the …

A novel liquid interface level sensor is presented that is able to determine the position of the
interface between a conductive and an insulating liquid. The sensor consists of an array of …
