Liquid level and density monitoring method employed in food, chemical industry, involves evaluating vibration of vibrating rods arranged immersed in liquid at two different modes and recognizing mass change in rods

摘要

The vibration frequencies of the vibrating rods (2) arranged immersed to defined depth in the liquid, are determined in two different modes, when excited by a tuning fork to determine the mass change in the rods. An Independent claim is also included for liquid level and density monitoring device.
