Measurement ball valve
Non-return protection for secure mounting
The patented non-return protection combines three functions in one device:
• Non-return protection
The sensor can only be pushed in one direction during installation. The sensor cannot return at all,
even if it is released.
• Seal
By means of an encapsulated O-ring, no compressed air can escape under pressure during assem-
bly.
• Precise positioning
The precise positioning with respect to immersion depth and orientation is easy to perform, guaran-
teeing accurate measurement results.
Mounting grip
With the mounting grip, the sensing probe is inserted and correctly positioned into the pipe line.
