Get Price#### Float Level Measurement

Float Level Measurement. Perhaps the simplest form of solid or liquid level measurement is with a float : a device that rides on the surface of the fluid or solid within the storage vessel. The float itself must be of substantially lesser density than the substance of interest, and it must not corrode or otherwise react with the substance. Floats may be used for manual "gauging" of level ...
