Measuring arrangement for process measuring technology for measuring a physical and/or chemical process variable of a process medium located in a container, said measuring arrangement having a measuring device having a process connection and a sensor housing placed thereon, wherein the process connection comprises a measuring cell housing having a measuring cell, characterised in that - a circumferential support is provided on the peripheral surface of the measuring cell housing, said support dividing the peripheral surface of the measuring cell housing into a first and second peripheral section (9a, 9b), - the process connection furthermore comprises a union nut having an internal thread and an internal annular stop, and - a tubular flange is provided with a first and second end (13a, 13b), said flange having an external thread on its first end which is formed correspondingly with the internal thread of the union nut, wherein the circumferential support of the measuring cell housing is able to be clamped between the flange and the union nut in two different mounting directions, wherein - for a first fastening concept, for the production of a connection of the first end of the flange to the measuring cell housing, on the one hand, the first peripheral section of the measuring cell housing is formed for insertion into the flange until the front-end first end thereof comes into contact with the support of the measuring cell housing and, on the other hand, the second peripheral section of the measuring cell housing is formed in such a way that, for the production of a threaded connection of the union nut to the external thread of the flange, the union nut is able to be pushed and unscrewed via the second peripheral section of the measuring cell housing and the support of the measuring cell housing thereby comes into contact with both the stop of the union nut and the front-end first end of the flange, and - for a second fastening concept, for the production of a connection of the first end of the flange to the measuring cell housing, on the one hand, the second peripheral section of the measuring cell housing is formed for insertion into the flange until the front-end first end thereof comes into contact with the support of the measuring cell housing and, on the other hand, the first peripheral section of the measuring cell housing is formed in such a way that, for the production of a threaded connection of the union nut to the external thread of the flange, the union nut is able to be pushed and unscrewed via the first peripheral section of the measuring cell housing and the support of the measuring cell housing thereby comes into contact with both the stop of the union nut and the front-end first end of the flange. -
