 22 Holder with welded bolts
1 Welding seam
2 Locking nut
3 Hole diameter max. 8.7 mm (0.34 in)
Installing sensor – small nominal diameters DN 15 to 65 (½ to 2½")
Requirements
• The installation distance is known
• Sensor holder is pre-assembled.
Material
The following material is required for mounting:
• Sensor incl. adapter cable
• Sensor cable for connection to the transmitter
• Coupling medium (coupling pad or coupling gel) for an acoustic connection between the
sensor and pipe
Procedure:
1. Set the distance between the sensors to the value determined for the sensor distance.
Press the movable sensor down slightly to move it.

b Sensor contact surfaces
2. Stick the coupling pad under the sensor onto the measuring pipe. Alternatively, coat
the contact surfaces of the sensor (b) evenly with coupling gel (approx.
0.5 to 1 mm (0.02 to 0.04 in)).
