Installation requirements VOAxxxxxxxxxxG1
Mounting recommendations:
• Minimum pipe diameter: 38mm (1.5”)
• Process connection direction:
Vertical: upwards flow with leak detection port facing down.
Horizontal: on the bottom or side with leak detection port facing down.
• Cable entry direction: from below
Installing 45/G1" Hygienic Welding adapter M548101, refer to datasheet for welding instructions.
Tightening torque: 60 +/- 20 Nm
Replacement o-ring 17x20mm EPDM/FPM/FFPM
Do not put sealing tape or paste on the threaded connection.

Installation requirements for Clamp connection: VOA xxxxxxxxxxTA / TB / TN
Mounting recommendations:
Tri-Clamp connections are hygienic and easy to install but they can trap air that can cause a malfunction.
•Distance from sensor lens to inner pipe wall should be kept to a minimum “d1”
• Minimum pipe diameter: 38mm (1.5”)
• Process connection direction:
Vertical: upwards flow
Horizontal: on the side
• Cable entry direction: from below
