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.
