accommodate the sensor shaft. ADS recommends using a 1.5-inch (38-mm) diameter
steel rod to test for interference to ensure the sensor shaft will fit into the pipe.
For assistance when installing the sensor taps or fittings, please contact the pipe
manufacturer or a professional pipe fitter.
Risk of accident!
Always use a mobile safety circuit breaker when working in a wet
environment and/or drilling into full pipes!
Please ensure the turnings can easily escape while drilling.
Interrupt drilling as necessary to remove turnings before
proceeding. Remove burrs with a file once drilling is complete to
prevent measurement errors.
Never burn pipes with welding torches!
A burn in a weld seam may cause swirls and, therefore, result in
measurement errors.

When assembling the pipe insertion sensor, use a special grease for
the stainless steel couplings (DIN 2353, or equivalent). Apply a
small amount of grease to the cap nut thread, threads, cone, and
cutting ring when pre-assembling the insertion sensor. The screw
joints come pre-greased from the manufacturer. Purchase
additional grease through ADS, when necessary.
