Abstract

Ultrasonic-Capacitance Integrated Liquid Level Sensors in oil storage using
ultrasonic and capacitance primary objective is to propose combination of technique
or system that is robust enough to measure the total liquid level and oil-water interface
level in crude oil tank by assuming the clear separation between water and crude oil.
In this case, a conventional capacitance oil-water interface level sensor is not robust
enough to give accurate oil-water interface when the tank is not full. Plus, the
conventional capacitance oil-water interface level sensor working principle ignores the
capacitance of oil by assuming the total effective capacitance is equal to water level
due to huge differences between oil and water dielectric permittivity. The risk of safety
issue such as overflow of tank has not been considered. The aim of a capacitance probe
is to measure the oil-water interface level in crude oil tank in real time and an ultrasonic
level sensor to measure the total liquid level in crude oil tank.
