Buoyancy level gauge
Liquid level gauges that use
the buoyancy of liquid to detect liquid levels are mainly used to detect the
liquid level in water tanks. Buoyancy-type liquid level gauges include
float-type, which detects the liquid level by the up and down movement of the
float, and ejector-type, which generates feedback force to form a servo mechanism
based on the change in the buoyancy of the ejector.
