When there is a risk of condensate forming between the process connection of the FTR20 and the
plug, we recommend using the process nozzle type FAR50 (→ 31), which is equipped with a
mounting flange with a pressure equalization element�

For process temperatures of +70 to +450 °C (+158 to +842 °F), plug-in adapters for stainless
steel flange nozzles of type FAR51 are available as accessories (→ 31).
For many processes, mounting with a spacer tube is a simple and cost-effective way of separating
the devices of the FTR20 flow indicator from the high process temperatures of +70 to +450 °C
(+158 to +842 °F)� The spacer tube can be secured in place in various ways, depending on the
application conditions (e.g. screwed into the process wall, bolted-on mounting brackets, welded or
clamped to available cross beams)�
We also recommend this mounting method for processes that are lined with clay or similar
materials on the inside� The spacer tube can be glued into place, for example�
