To facilitate zero adjustment and maintenance, providing a bypass line is recommended.
- Please prevent the detector from pipeline stretching, vibration or shock.
- Please prevent the detector from direct xing. (See gure below.)Please prevent the detector from direct xing. (See gure below.)
- Please x the pipe at rst and support the detector with piping. (See gure below.)
- Please x only one side of the detector instead of both sides so as to minimize mechanical stress to the
detector.
Makes pipe easier to empty (in case of maintenance, start-
up, product change). Helps gas bubbles to escape.
Only one shut-off valve is required to ensure
“no ow” for
setting Autozero.
For liquids: Measuring tube downwards so that no gas can
collect if “no ow”.
For gasses: Measuring tube upwards so that no liquid can
collect if “no ow”.
Avoid it, as this can lead to collection of gas bubbles.
Avoid it, as suction can draw air into the measuring tube,
leading to incorrect measurements. Free outlets
to contain-
ers or vessels can generate low pressure
by earth gravity
acceleration.

WARNING
• Do not stress the detector mechanically. Fix the pipe not on both ends of the detector but only at one
side. Let the other side run free for minimum mechanical stress on the detector.
• Please use the standard reducers if the piping’s cross- section differs at the inlet or outlet point of the
owmeter.
