5.1.1 Supplementary Installation Information
In the high temperature design the multi-connection plug is separated from the sensor housing by a pipe.
Thereby the plug can still be accessed even when the sensor is insulated.
The mounting bracket included with the shipment should always be used. The bracket should be secured
to a wall or a steel framework (vibration free and mechanically stable).

Important!
If there are large differences between the fluid and ambient temperature the sensor must be insulated, to
prevent two phase flow and accuracy effects. This is especially important for low flowrates.
The sensor must
always be completely filled with homogeneous liquid or a single phase gas, otherwise the
accuracy could be adversely affected.
For air/gas in volatile fluids horizontal installations are recommended.
