Housing
The Model GD-K11D’s steel housing is radio frequency (RF)-resistant. It is suitable for
installation
in indoor areas where general purpose equipment is in use.
The housing cover is hinged on the front bottom edge and is secured by a thumbscrew on
the top of the housing. The flowmeter, display screen, and status lights are visible through
windows in the housing cover. The cover also includes two labels that indicate the target
gas and detection range of the Model GD-K11D.
Three 3/8 in. cable fittings on the bottom of the housing allow you to make external
wiring connections. The gas out fitting to the right of the cable fittings allows the gas
sample to exit the Model GD-K11D after the sample passes through the sample system.
The gas in fitting above and to the right of the gas out fitting allows the gas sample to
enter the Model GD-K11D. The gas in and gas out fittings accept 6 mm OD x 4 mm ID
PTFE tubing.
Two mounting flanges are attached to the back of the housing. The top flange includes
two mounting slots; the bottom flange includes two mounting holes. The flanges allow
you to install the Model GD-K11D to a vertical surface at the monitoring site.
