HUNTER FLOW-CLIK SENSOR:
Automatically shuts down irrigation system if an overflow condition occurs.

A ruptured pipe or broken sprinkler that is left undetected can result in a substantial amount of damage. Plants and ground cover can be flooded; a slope can be eroded; even solid surfaces such as sidewalks or driveways can be undercut. The installation of a Flow-Clik can help identify a break before any damage can occur. The Flow-Clik is user-set to activate at a specified level of flow; once that level is exceeded; the electrical circuit is broken and the valves are shut off. As a result; the amount of water loss in the event of high external leakage would be substantially reduced.

	ET and Irrigation: Working with Climate Plants evaporate moisture through their leaves; and replenish it through their roots. In turn; conditions such as temperature; humidity; and wind dictate the rate at which the plants lose their moisture. ET-based irriga­tion measures these conditions and replenishes only the amount of water lost to plant evaporation. Factors such as the precipitation rate of your sprinklers; the crop coeficient of your plant types; and the infiltration rate and holding capacity of your soils are taken into account with simple menu No More Sprinklers Running in the Rain! Each ET System has a simple user interface; so you can select from a menu of common sprinkler; plant; and soil types; or create your own custom factors. The system’s sensor array includes solar radiation; relative humid­ity; temperature; a rain gauge that tracks precipitation; plus an optional anemometer for wind speed. The ET System stops wasteful irrigation after naturally occurring rainfall; and automatically resumes sprinkler operation when conditions return to dry.
Evapotranspiration and Hunter: Leading the Way! Evapotranspiration is a formula; based on weather conditions; which has been created through exhaustive research and experimen­tation by irrigation professionals. ET has come to symbolize the “best practice” for determining landscape watering needs. Hunter helped to pioneer this field of auto­matic irrigation; and has ofered ET-capable irrigation controllers for over 15 years. Now; the ET System brings this proven technology to a simple; afordable package that lets all of us irrigate responsibly. Weather Data at Your Site - (Not from Somewhere Else) Hunter's ET System requires no subscription fees; and is not based on any form of broadcast or other distant weather data. Your irriga­tion schedule is based on actual conditions in your landscape. The ET System was designed to exceed standards developed by the Irrigation Association and government agen­cies; using Smart Water Application Technology to minimize waste; while creating healthier landscapes.
