8.3.1 Mounting the Transducers with Portable Variofix Rail with Chains
Normally, each transducer is mounted to its own Variofix rail. If the transducer distance is
small and both transducers are on the same side of the pipe (reflection mode), they can
be fixed in one Variofix rail.
Preparing and fixing the variofix rail
• Adjustment of the Variofix rail to transducer width:
- Loosen the 4 screws (1) for the adjustment of the rails (2) with a M8 wrench (see Fig.
8.7).
- Place one transducer (3) in the center between 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 tensioners (4), but do not unscrew them completely.
• If the chain has not yet been mounted to the rail support (6):
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) must be completely supported
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) completely in and push the ball chain (8) in the other
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.
Fixing the transducer
• Force apart the legs of the spring clip (10) 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 transduc-
er.
• Apply some coupling compound to the contact surface of the transducer.
• Place the transducer between the rails (2). Observe the mounting direction (see Fig.
8.7).
• 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).
