G01F 23/24

by measuring variations of resistance of resistors due to contact with conductor fluid

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Indicating or measuring liquid level or level of fluent solid material, e.g. indicating in terms of volume or indicating by means of an alarm > by measuring physical variables, other than linear dimensions, pressure or weight, dependent on the level to be measured, e.g. by difference of heat transfer of steam or water > by measuring variations of resistance of resistors due to contact with conductor fluid

CPC:

Indicating or measuring liquid level or level of fluent solid material, e.g. indicating in terms of volume or indicating by means of an alarm > by measuring physical variables, other than linear dimensions, pressure or weight, dependent on the level to be measured, e.g. by difference of heat transfer of steam or water (involving the use of floats G01F23/30) > by measuring variations of resistance of resistors due to contact with conductor fluid

Of 3 combined children, 0 exist in both systems.

3 codes are CPC-only extensions.
