User guide

The standard ﬂ ange sizes are either 2” or 3” 150# R.F. ANSI as well as DN50 and DN80. Please check the exact

ﬂ ange size speciﬁ ed and provided for the particular installation. Other ﬂ ange sizes and a variety of materials (to

suit the process) are available so please check these details prior to installing the ﬂ anges on the process.

Note: The process isolation valves should have at least a 1½” (38mm) diameter clear bore size

(aperture) to ensure there is sufﬁ cient tolerance to align the laser beam after installation. Ducts and

Stacks that have thin and ﬂ exible walls should be reinforced to ensure that the laser beam alignment is

maintained at all times. Rigid mounting for the process ﬂ anges is highly recommended to ensure a

lignment is maintained.

In situations where the process ﬂ anges are mounted to these thin and ﬂ exible duct/stack walls, a larger

reinforcing plate should be welded around the mounting ﬂ ange area to increase the attaching region. The ﬁ gure

below depicts a typical suggestion however; it is the installer’s responsibility to ensure appropriately rigid

installation is provided for the analyzer.
