HydroPoint data systems inc. WT008 用户手册

The ET Everywhere Service provides accurate ET down to one
square kilometer, automatically adjusting the water flow with
changes in your local weather conditions. The ET Everywhere
Service is centrally managed at a HydroPoint Data Center.

HydroPoint offers the irrigation industry’s

most professional and personalized customer support. We’re
here to answer any questions you have: from understanding 
how to install the WeatherTRAK ET plus to questions about
horticulture, water conservation, and proper plant maintenance.

ET is a scientific formula that determines the amount of water
lost from a plant and its soil due to transpiration and
evaporation caused by weather conditions.

If you need help, just call us at: (800) 362-8774 or look us up on the
web at: www.hydropoint.com.

Although the WeatherTRAK ET plus eliminates most adjustments, it’s
only as good as your overall irrigation system. 

You or your contractor still need to inspect your system at least once
a month to ensure its operating at its peak efficiency. 

Remember that your landscape will likely need to be tuned and
reconditioned. It will take time and a phased-in approach to develop
an optimal water schedule. But with the WeatherTRAK ET plus, you
will begin to see dramatic results in water savings and plant health
within a few short weeks or months.

First, the WeatherTRAK ET plus controller automatically calculates a
program that matches your landscape’s specific needs. Next, the ET
Everywhere Service analyzes the weather conditions in your area,
and automatically broadcasts customized irrigation adjustments
directly to your controller, twenty-four hours a day, seven days a
week. This revolutionary technology ensures the most accurate, 
cost-effective irrigation ever devised.

The WeatherTRAK ET Plus System

The WeatherTRAK ET plus offers three key solutions to your irrigation
needs:

You simply enter

basic information about your landscape into the WeatherTRAK ET
plus and the controller automatically sets a scientifically based,
customized schedule for you.

HydroPoint obtains weather station

data from a host of public and private partners including NOAA,
cities, states, universities, water districts and other organizations
that own and manage weather station networks or individual
weather stations.

HydroPoint collects, analyzes and validates weather data
gathered from thousands of weather stations. We utilize these
weather stations to provide input parameters for our local
evapotranspiration (ET)* calculations.

Across the U.S. each 
day, a vast network 
of weather stations 
transmit weather
data to the NOAA 
satellite.

HydroPoint dowloads
weather data from the
NOAA satellite and from
other weather data sources.

HydroPoint 
transmits ET 
data to its 
wireless
network.

HydroPoint's data analysis 
process uses this weather 
data to calculate 
location-specific ET down 
to a square kilometer.

HydroPoint's wireless 
network broadcasts 
location-specific ET data 
to WeatherTrak ET Controllers.

WeatherTrak ET Controllers 
automatically adjust irrigation 
output as weather changes, 
ensuring maximum water 
conservation, run off reduction 
and landscape health.
