Abstract
Abstract An apparatus for measuring water impurities in oil comprises a confined space in which the oil is heated to a temperature higher than the evaporation temperature of water. In accordance with the invention, the confined space is a chamber arranged between an inlet and an outlet and having heating means and temperature control means, said chamber being adapted, by way of valves provided in the inlet and the outlet, to form a closed system. The chamber has an expansion vessel connected thereto, which is of variable volume and has means for emptying it. Further, the closed system is provided with means for measuring and/or controlling the change of state produced by the heating of the oil.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
An apparatus for the discontinuous measurement of water impurities in oil by heating the oil in a confined space to a temperature higher than the evaporation temperature of water comprising: a container having a chamber with inlet and outlet means, said container having heat and temperature control means; at least one expansion vessel connected with said chamber, said expansion vessel being a cylinder and piston unit with the piston of said unit being adapted to be actuated by the volume increase of the oil which is responsive to the elevated temperature, and said cylinder having means for emptying the oil; said chamber and said expansion vessel forming a closed system through said inlet and outlet means, and said closed system having means for regulating and measuring the pressure produced by the heating of the oil, whereby the oil is degasified by reducing the volume in the expansion vessel and the heating of the oil in said chamber so that said measurement can be made.
Claim 2
Independent Claim
164 words
An apparatus for the discontinuous measurement of water impurities in oil by heating the oil in a confined space to a temperature higher than the evaporation temperature of water comprising: a container having a chamber with inlet and outlet means, said container having heat and temperature control means; at least one expansion vessel connected with said chamber, said expansion vessel being a cylinder and piston unit with the piston of said unit being adapted to be actuated by the volume increase of the oil which is responsive to the elevated temperature, and said cylinder having means for emptying the oil; said chamber and said expansion vessel forming a closed system through said inlet and outlet means, and said closed system having means for regulating and measuring the pressure produced by the heating of the oil, whereby the oil is degasified by reducing the volume in the expansion vessel and the heating of the oil in said chamber so that said measurement can be made.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 including a buffer means for the heated oil between said chamber and said expansion vessel.
Claim 4
Dependent Claim
27 words
The apparatus of claim 1 including a dome at the top of said chamber for gases leaving said oil and said outlet means extending from said dome.
Claim 5
Dependent Claim
17 words
The apparatus of claim 1 including expansion vessels of various volumes adapted for connection with said chamber.
