E Hauser 13
Orientations B, C and D are possible with horizontal installation (see Page 13).
The arrow indicated on the device must always point in the direction of flow in all orientations.

Caution!
• If fluid temperature is
≥
200 °C, orientation B is not permitted for the wafer version
(Prowirl 72 W) with a nominal diameter of DN 100 and DN 150.
• In case of vertical orientation and downward flowing liquid, the piping has always to be
completely filled.

3.2.4 Heat insulation
Some fluids require suitable measures to avoid heat transfer at the sensor. A wide range of materials
can be used to provide the required insulation.
When insulating, please ensure that a sufficiently large area of the housing support is exposed. The
uncovered part serves as a radiator and protects the electronics from overheating (or undercooling).
The maximum insulation height permitted is illustrated in the diagrams. These apply equally to both
the compact version and the sensor in the remote version.

Caution!
Danger of electronics overheating!
• Therefore, make sure that the adapter between sensor and transmitter and the connection
housing of the remote version is always exposed.
• Note that a certain orientation might be required, depending on the fluid temperature
