Survey on Detecting Method of Liquid Level of Tank

The accurate measurement of liquid level of tanks is an important role in management and safety production. There are some common methods to detect liquid level of tank, such as hand gauging measurement, differential pressure liquid measurement, magnetostriction liquid level measurement, ultrasonic liquid level measurement, radar liquid level measurement, fiber-optical liquid level measurement. The basic principle, advantage and disadvantage, detection range and accuracy of every method of detecting liquid level of tank are presented in detail in the paper, and meanwhile a comparative analysis is given.
