The Rain Master Weather Center allows the irrigation system to optimize
water usage by replacing only as much water as was used by the
turfgrass.
The simplicity of the system has given it a major advantage in cost and
effectiveness.
The Rain Master Weather Center II will directly model the ET
(evapotranspiration) on any given site. The factors below are accounted
for by the system:
•
Air Temperature
•
Wind Speed
•
Relative Humidity
•
Solar Radiation
All of the above factors must be constantly monitored and measured,
with average readings produced, and finally logged. The Weather
Computer automatically and directly reads every change throughout the
measurement period, and factors it directly into the ET calculations.
Summary:
•
Precise readings of ET values
•
Direct modeling of a microclimate
•
Very low to no maintenance for a full season
•
Inexpensive to purchase and operate
•
Does not require shutdown or preventive measures during freeze
With the use of the Rain Master Evolution Central Computer or the RME
Eagle iCentral, daily accumulated ET readings are processed and
watering schedules are adjusted accordingly. When a watering zone
microclimate is hot, windy or dry, the ET values will increase resulting
in a heavier watering schedule. When the microclimate becomes cooler
or increases in humidity, the watering schedule will be adjusted to a
lower percentage of station run times, thus reducing water usage.
The Rain Master Weather Center is connected to one controller of an
irrigation system, which is set up to gather accumulated ET data for the
24 hour period between 12:00 AM and 12:00 midnight. The final totals
are uploaded to the Evolution Central Computer each day for processing
and reports.
