4.6.4.2 DM240FA Duct Installation Flange
DMT143 models with a G1/2” ISO228/1 connection thread can be installed directly in the
process wall through a 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.
