OPTICAL RAIN GAUGE
MODEL RG-11
INSTALLING THE RAIN SENSOR
1. Determine the Mode / Set DIP switches
You must set the DIP switches so that the RG-11
behaves the right way for your application. The pages
that follow describe each of the possible modes, and
how to set the DIP switches.
2. Mount the Rain Gauge
Mount the rain Gauge where it gets a clear
measurement of precipitation– away from overhangs,
etc.
The mounting arm is designed to fit over a strap 0.75”
(19 mm) wide. Two 0.25” (holes 6.35 mm) are placed
0.75” (19 mm) part.
The gland style connector goes in the bottom hole. Be
sure to use wire rated for outdoor (high-UV) use.
For conduit applications, the mounting arm may be
removed, and the wiring hole drilled out using a step drill
to accommodate a ½” EMT compression connector or
similar style of conduit connector.
3. Assemble the Rain Gauge as shown.
The silicone O-ring fits nicely in the lens groove, but it
can fall or slip out during assembly. After the unit is
assembled, verify that the O-ring is properly seated by
confirming that you can see it through the lens, all the
way around.
The Rain Gauge must be assembled when dry. Any
water trapped inside can condense and cause corrosion.
You may optionally add extra desiccant packets (not
supplied). If the Rain Gauge is not subject to splashing
or sprayed water, you may optionally vent the enclosure

- APPLICATION WARNING -
Do not use the RG-11 in any application where the false
indication of water or a missed valid detection of water
could cause damage to life or property. It is the
responsibility of the system designer / integrator to
design redundancy into the system so that the failure of
any one component, including the RG-11 or other
sensor, does not result in disaster. The manufacturer of
the RG-11, Hydreon Corporation, will in no way be
liable for consequential damages due to the failure or
false indication of one of its sensors.
