If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
You can order a weather protection cover from Endress+Hauser. → 169.
Thermal insulation
For optimum temperature measurement and mass calculation, heat transfer at the sensor
must be avoided for some fluids. This can be ensured by installing thermal insulation. A
wide range of materials can be used for the required insulation.
This applies for:
• Compact version
• Remote sensor version
The maximum insulation height permitted is illustrated in the diagram:
