Hauser 41
3.10 Installing Prosonic Flow W (Clamp-on)
3.10.1 Installation for measurement via one traverse
Prerequisites
• The installation distances (sensor distance and wire length) are known
→
ä
16.
• The strapping bands are already mounted
→
ä
30.
Material
The following material is needed for mounting:
• Two strapping bands incl. mounting bolts and centering plates where necessary
(already mounted
→
ä
30)
• Two measuring wires, each with a cable lug and a fixer to position the strapping bands
• Two sensor holders
• Coupling fluid for an acoustic connection between the sensor and pipe
• Two sensors incl. connecting cables.
Procedure
1. Prepare the two measuring wires:
– Arrange the cable lugs and fixer such that the distance they are apart corresponds to the wire
length (SL).
– Screw the fixer onto the measuring wire.

2. With the first measuring wire:
– Fit the fixer over the mounting bolt of the strapping band that is already securely mounted.
– Run the measuring wire
clockwise around the pipe.
– Fit the cable lug over the mounting bolt of the strapping band that can still be moved.
3. With the second measuring wire:
– Fit the cable lug over the mounting bolt of the strapping band that is already securely
mounted.
– Run the measuring wire counterclockwise around the pipe.
– Fit the fixer over the mounting bolt of the strapping band that can still be moved.
4. Take the still movable strapping band, incl. the mounting bolt, and move it until both
measuring wires are evenly tensioned and tighten the strapping band so that it cannot slip.
