METHOD FOR ANALYSIS OF A LIQUID WITH A SAMPLING UNIT FOR A LIQUID SAMPLE ADAPTED TO BE FITTED INTO A SYSTEM WITH TEMPERATURE VARIATIONS

摘要

The invention relates to a sampling unit (100) for a liquid sample, preferably for a fuel intended for a combustion engine (2), which sampling unit (100) is adapted to be fitted into a system with temperature variations, which system contains or transports a liquid to be analysed. The sampling device (100) comprises a wall section (104), partly surrounding a cavity (101), which is liquid filled, and an opening (103), through which the liquid in the cavity may flow out of the cavity (101) when the liquid expands at temperature increases and through which the liquid in the system may flow into the cavity (101) when the liquid in the cavity is compressed at a temperature drop. The opening is equipped with a channel (120), which may hold a specified volume of liquid, and which channel (120) is arranged to be in contact with the liquid in the system.
