Installation
1. Place the threaded end of the device onto the thread of the connecting pipe
2. Fasten the adapter union of the pipeline with a suitable spanner (1). When doing so, lock the
process connection of the device in place to prevent slip, using a suitable spanner (2).
3. Keep turning in the adapter union (1) while holding the process connection of the device
locked (2) until the connection is tight.
4. Repeat these steps at the other end of the device.
Initial startup
The following steps must be taken before initial startup and any subsequent startup (e.g. after remo-
val and installation during maintenance).
•
Make sure that the plant is operating vibration-free. Vibrations could destroy the device.
•
Make sure that the medium is flowing continuously. Pulse-like staggered loads could destroy
the device.
•
Completely fill the pipelines. Partial filling(s) may result in malfunctions and damage to the
device.
•
Vent the pipeline. If there are air bubbles in the line during the measurement, this could re-
sult in damage to the device caused by hydraulic shock. This may cause malfunctions.
•
Make sure that the plant is operating without cavitation. Cavitation may result in malfuncti-
ons and damage to the device.
