Provided herein is an apparatus for determining a vertical density profile of a multi-layered fluid column including at least two different liquids, the apparatus comprising a plurality of measurement modules that form a vertical array of measurement modules; wherein each measurement module comprises: a support arm mounted to the elongate vertical support member and extending outwardly from the elongate vertical support member; a displacer carried on the support arm; and a force measurement device configured to measure a force attributable to a mass of the displacer mediated by a buoyancy of the displacer in the fluid column, wherein the plurality of measurement modules have a data connection to a data processing unit that is configured to process the measurement data from the plurality of measurement modules and generate a level or density profile of the fluid column.

The refrigerant compressor includes a compressor casing (2); an oil sump (13) arranged in the compressor casing (2); and an oil level sensor arrangement (14) configured to detect an oil level in the oil sump (13), the oil level sensor arrangement (14) including a tubular element (16) secured to the compressor casing (2) and a floating element (17) surrounding the tubular element (16) and being movably mounted with respect to the tubular element (16). The compressor casing (2) includes a passage opening (24) and dimensions of the tubular element (16), the floating element (17) and the passage opening (24) are defined to allow an insertion and a removal of the tubular element (16) and the floating element (17) into and out of the compressor casing (2) through the passage opening (24).

A liquid level detecting apparatus of a tank for a vehicle is provided. The apparatus includes a main detecting part that detects the liquid level of the liquid in a tank to output a liquid level detection signal corresponding to the liquid level and an auxiliary floater assembly that has an auxiliary floater provided to float on the liquid surface of the liquid in the tank. A gyro sensor is mounted to the auxiliary floater, and an angle detection signal corresponding to an inclined angle of the tank is output by the gyro sensor. A controller determines a final liquid level value by correcting a liquid level value obtained from the liquid level detection signal based on the angle detection signal.
