Mounting
When measuring in diagonal arrangement, the transducer mounting fixtures are mounted on opposite sides of the pipe,
see Fig. 6.8. When measuring in reflection arrangement, the transducer mounting fixtures are mounted on the same side
of the pipe, see Fig. 6.9.
When measuring in diagonal arrangement with 2 beams in displaced X arrangement, 4 transducer mounting fixtures have to
be mounted. When measuring in reflection arrangement and small transducer distance, only 1 transducer mounting fixture
has to be mounted, see Tab. 6.1.
In the following, the mounting of 2 transducer mounting fixtures in reflection arrangement is described (1 transducer
mounting fixture for each transducer).
Overview of the mounting steps
• step 1

• step 2
fixing the clasps to the tension straps
• step 3
fixing the tension strap to the pipe
• step 4
fixing the rail to the pipe
• step 5
installation in the transducer mounting fixture Variofix L
