US 5,854,072 A · Method and apparatus for determining product-specific quality parameters of a liquid

Abstract

The invention relates to a method and an apparatus for determining product-specific quality parameters of liquid, especially liquid (14) containing alcohol and held in a container (12) such as a bottle or can, the quality parameters being determined by means of sensors (22, 24, 26). To enable performing measurements with simply provisions and without complicated specimen preparation, and avoiding cross-sensitivities, it is proposed that the quality parameters of the liquid are determined under the conditions prevailing in the container, and liquid is initially delivered, under the pressure prevailing in the container, to a temperature unit (32) and adjusted to a temperature that corresponds to that of the sensors, and is then delivered to the sensors.

Dependent claims

A method for determining at least one parameter of a liquid held in a closed container under pressure, comprising the steps of:

inserting into the container a gas injection line and a liquid removal line, without opening the container to atmosphere;
injecting into the container, through the gas injection line, a gas which is inert to the liquid, the injecting causing liquid to flow through the liquid removal line under pressure equivalent to the pressure in the container;
determining the temperature of a sensor for determining said at least one parameter, and adjusting the liquid in the liquid removal line to said determined temperature;
and
passing the liquid at said determined temperature to the sensor to determine said at least one parameter.
