Abstract

A gas and/or liquid tubular duct has a measurement line (12) arranged next to the tubular body (10). Both the tubular body (10) and the measurement line (12) are contained together in a gas- and/or liquid-tight casing (14). The casing is interiorly designed in such a way that at least in the direct contact area with the tubular body (10) through communicating channels extend between the casing (14) and the tubular body (10).
