DM240FA Duct Installation Flange
The transmitter can be installed directly in the process wall through
DM240FA duct installation flange. When the transmitter is installed
directly on the process wall or pipe, note that a closing valve may be
needed on both sides of the installed transmitter so that the sensor head
can be removed from the process for calibration or maintenance.
