Mounting
When measuring in diagonal arrangement, the transducer mounting fixtures are mounted on opposite sides of the pipe.
When measuring in reflection arrangement, the transducer mounting fixtures are mounted on the same side of the pipe.
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 with a small transducer distance, only 1 transducer mounting
fixture has to be mounted.
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
disassembly of the transducer mounting fixture Variofix L
•
step 2
fixation of the clasps to the tension straps
•
step 3
fixation of the tension strap to the pipe
•
step 4
fixation of the rail to the pipe
•
step 5
installation of the transducers in the mounting fixture Variofix L
