6.2.2.2
Transducer arrangement
The transducers can be arranged in the mounting rails in different ways:
6.2.2.3
Order of transducer mounting
The transducers are mounted using the corresponding mounting fixtures. Observe the following steps:
• Mount the transducer pair A in diagonal arrangement with 1 sound path at the transducer distance a and with the arrows
pointing in the flow direction.
• Mount the transducer pair B in diagonal arrangement with 1 sound path at the distance Δx from transducer pair A and
with the arrows pointing in the flow direction.
– Mount the transducer B
1
at the distance Δx from transducer A
1
, if possible with an accuracy of 1 mm.
– Mount the transducer B
2
at the distance Δx from transducer A
2
, if possible with an accuracy of 1 mm.
– Check whether the transducer distance of transducer pair B corresponds to the required distance a.

all transducers in one pair of rails
a small, Δx small
each transducer pair in its own pair of rails:
a small, Δx large
transducers distributed over 3 rail positions:
a large, Δx large
Notice!
In case the recommended distance between the measuring barriers displayed by the transmitter cannot be set
because of the transducer size, mount the transducer pair B at the smallest possible distance to transducer pair A.
Make sure to keep a few millimeters distance between the transducers of measuring barrier A and B. The
transducers should not touch.
