Calsense
Tipping Rain Bucket (model RB-1)
The Calsense Tipping Rain Bucket allows an ET2000e controller with the -RB interface to keep a record of
accumulated rainfall (Figure 16
). The Tipping Rain Bucket consists of a tipping mechanism that measures
every 0.01 inches of rainfall. The measured water drains out of the bottom of the housing. Therefore,
the bucket requires no attention or service of any kind.
The ET2000e controller connected to the Tipping Rain Bucket receives this information and, using the
rate and actual amount of rainfall, offsets each station’s run times accordingly.
Rain measurements from the Tipping Rain Bucket can be shared automatically between controllers using
FLOWSENSE technology or using the Calsense Command Center Central Water Management Software.

Rain Bucket Cable
The Tipping Rain Bucket is shipped with 25 feet of two-conductor cable. The maximum length of cable is
1,000 feet using Paige P7171D communication cable. For runs under 100 feet, 18-gauge multi-conductor
irrigation wire, in conduit, may be substituted. It is highly recommended that the cable be installed in
conduit to connect the Tipping Rain Bucket to a controller with the -RB interface. Runs are to be direct
pulls without splices.
Wind Gage (model WG-1)
Wind speed can be monitored by a Calsense ET2000e controller using a Calsense Wind Gage (Figure 17).
The irrigation controller connected to the Wind Gage is specified with a -WG interface option. The Wind
Gage sends pulses to the ET2000e, which automatically pauses irrigation once the wind speed exceeds a
