Continuous-type liquid Level Measurement System using pulsating sensor

Abstract

A high resolution liquid level monitoring device using pulsating sensor based instrument is presented. The technique involves precise measurement of h y drostatic pressure exerted b y the process liquid using a high sensitive pulsating t y pe differential pressure sensor and correlating it to the liquid level.A digital approach has been explored to monitor the liquid level in a reservoir, sensitivel y up to 1 m range with an accurac y of -1 %. The measurement s y stem resembles conventional bubbler method, but the process of bubbling is totall y avoided and makes the method eas y deplo y able. A protot y pe level measurement s y stem is designed for 1 meter tank and tested for its performance.Index Terms-liquid level measurement, h y drostatic principle, pulsating sensor

A New Methodology-Based Sensorial System with Which to Determine the Volume of Liquid Contained in a Cylindrical Tank Subjected to Full Variations in Its Orientation

“…However, several technologies and methodologies with which to quantify the volume of liquid contained in a tank exist within the industrial sector [22]. For example, continuous-height liquid measurement [23] considers the geometric characteristics of the tank (cylinders, spheres, rectangles, squares with semi-spherical ends, etc.) and is employed to calculate the volume of the liquid contained inside the tank.…”

Non‐uniform sampling and super‐resolution method to increase the accuracy of tank gauging radar

“…Different methods are proposed for liquid level measurement. Majority of these methods use in‐contact mechanical parts or are based on mechanical waves [1]. All these methods are vulnerable to temperature or pressure changes and ageing [2].…”
