In order to provide means for allowing a time and cost effective use of measurement instruments ( 1, 21, 22, 41, 55 ) in industrial applications where high standard of hygiene need to be fulfilled, a disposable sterilizable liner ( 15, 27, 28, 51, 67 ) for a level, pressure or temperature measurement instrument ( 1, 21, 22, 41, 55 ) for measuring level, pressure or temperature of a product ( 9 ) in a container ( 3 ), for use in combination with a disposable container liner ( 13 ) covering an interior of the container ( 3 ), is described, wherein the measurement instrument ( 15, 27, 28, 51, 67 ) comprises: a sensing element ( 5, 23, 47, 59 ) for sensing a physical quantity, and a process connector ( 7, 25, 43, 57 ) for mounting the sensing element ( 5, 23, 47, 59 ) on a counter connector ( 11, 29, 53 ) on the container ( 3 ), wherein the liner ( 15, 27, 28, 51, 67 ) for the measurement instrument ( 1, 21, 22, 41, 55 ) is one integral element made out of an elastic material has a shape that exactly follows outer contours of the sensing element ( 5, 23, 47, 59 ) and the process connector ( 7, 25, 43, 57 ), such that it forms a removable single use hygienic liner for closely covering all surfaces of the measurement instrument ( 1, 21, 22, 41, 55 ) exposed to the product ( 9 ) during measurement operation, and comprises a mounting section ( 17 ), which in operation is clamped between the process connector ( 7, 25, 43, 57 ) and the counter connector ( 11, 29, 53 ).
