ABSTRACT:
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).
