Mounting In Front Of Microwave-Impermeable; Process Wall - Endress+Hauser Solimotion FTR20 Technical Information

Solimotion FTR20
Mounting in front of
microwave-impermeable

process wall

Endress+Hauser
For applications with a high process pressure up to 2 MPa (20 bar) absolute, we recommend the
following high pressure adapter (accessories → 31).

13 Mounting with high-pressure adapter
The maximum temperature at the FTR20 must be observed�
If, due to the process conditions (such as high temperatures, high pressures or hazardous nature of
the material), no direct installation in the microwave-impermeable process wall is possible, the flow
indicator can emit its signal through an additionally installed plug�
The following materials have been tested and are suitable for radiation:
• Plastics (virginal, unfilled) such as polytetrafluorethylene (PTFE), polyethylene (PE) or
polypropylene (PP)
• Aluminum oxide ceramic (purity min� 99�5 %, uncolored)
• Borosilicate glass (uncolored)
Colorations or added (colored) substances can cause a potentially high signal attenuation,
depending on the material, and are therefore not suitable for this purpose�

-40 °F to +158 °F
14 Bracket mounting in front of a microwave-permeable process wall
• With bracket mounting in front of a microwave-permeable plug and the risk of the formation of
condensate on the inner wall of the container, we recommend a plug protruding into the process
(1)�
• The maximum temperature at the FTR20 must be observed�
• Distance A is based on the clear opening area D� To prevent possible signal attenuation, we
recommend keeping the distance as short as possible (e.g. max. 40 mm at DN50).
