3.6 Mounting of inline version
The inline sensor is mounted through a ball valve to make it possible to remove the sensor
under pressure. Make sure there is at least 260 mm / 10.2" free space to remove the sensor
from the valve. The sensor shall be mounted in a place where the process pressure is at least
1 bar. In horizontal pipes the sensor shall be mounted from the side or from below to avoid
disturbance from air bubbles.
The sensor is designed to be mounted in a right angle to the process flow. The smallest process
pipe diameter to mount the sensor is 80 mm / 3.1". The measure gap must be at least 5 mm /
0.2" from the pipe wall. If a sample outlet is used it must reach at least 20 mm / 0.8" into the
pipe.
Place the sensor at a location where there is no risk for it to get damaged. When the OAS 2000
inline is used outdoors, it shall be mounted with a sun and rain protective hood.
CAUTION!
Be aware that the force may be strong when the sensor is mounted under pressure.
CAUTION!
If the following instructions cannot be fulfilled in all parts, the sensor should not be mounted or
dismounted under process pressure.
