6.2.2.4 Installation of the transducers with portable Variofix rail and chains
Normally, each transducer is mounted in its own Variofix rail. If the transducer distance is
small and both transducers are on the same side of the pipe (reflection arrangement),
both transducers can be fixed in one Variofix rail.
Installation of the Variofix rail
• Adjustment of the Variofix rail to transducer width:
– Loosen the 4 screws (1) for the adjustment of the rails (2) with an M8 wrench, see
Fig. 6.10.
– Place one transducer (3) in the center of the rails.
– Press the two rails (2) together and tighten the 4 screws (1). The transducer can be
shifted and removed.
– Remove the transducer.
• Loosen the chain tensioner (4), but do not unscrew it completely.
• If the chain has not been mounted in the rail support (6) yet:
Compress the spring of the chain tensioner (4) with the cylinder (7) while pushing the
chain tensioner (4) in the horizontal groove (5) of the rail support (6).
• Place the Variofix rail on the pipe. Both rail supports (6) have to be completely support-
ed by the pipe. Lay the ball chain (8) around the pipe (if the pipe is vertical, start with the
upper ball chain).
• Press the chain tensioner (4) inside completely and push the ball chain (8) into the oth-
er groove (9) of the rail support.
• Fix the second ball chain (8) in the same way.
• Tension the ball chains (8) by tightening the chain tensioners (4).
• Repeat the steps if the second transducer is fixed to its own Variofix rail.
Installation of the transducer
• Force the legs of the spring clip (10) apart and clamp it over the outer side of the rails (2).
The height where the spring clip will snap in depends on the height of the transducer.
• Apply some coupling compound to the contact surface of the transducer.
• Place the transducer between the rails (2). Observe the mounting direction, see Fig.
6.10.
• Push the spring clip (10) over the transducer until the knurled screw (11) is positioned
over the blind hole of the transducer.
• Fix the transducer by tightening the knurled screw by hand (11).
• Repeat the steps for fixing the second transducer.
• Adjust the transducer distance by loosening the knurled screw (11) of a spring clip (10)
and shifting the transducer.
