EvapoIrrigator - Model MK1.1 - Accurate Irrigation Controller
Replaces expensive weather station. Links to existing controllers. Evapotranspiration measured by single reliable sensor. Takes the guesswork out of irrigation. Matches irrigation to crops’ needs. Versatile and simple to use for °hour accumulation. Responds to all environmental factors affecting water loss. Automatic °hour adjustment with weather and environment. Saves water, improves quality, reduces errors, increases profits.
The EvapoIrrigator MK1.1 is an exciting addition to the E&TS Ltd range of irrigation control equipment. It offers growers automatic adjustment of irrigation frequency according to weather conditions. Fitting an EvapoIrrigator to a simple irrigation timer transforms it into an intelligent controller that will reduce water wastage, improve crop quality and ultimately boost the bottom line. It is compatible with any existing timer/controller that can accept a remote start signal. The key feature of the EvapoIrrigator is its ability to integrate the signal from the ES4 pt100 Evaposensor. It triggers irrigation when accumulated evaporation reaches a user adjustable target value.
Installation is straightforward and flexible.
When used as a ‘stand alone’ integrator, the controller will provide a start for an irrigation controller, with degree hour integration adjustable from 1°h to 999°h. When the number of degree hours accumulated reaches the set adjustable targer, a potential free start relay contact closes for 5 seconds.
The output current loop, 0 - 20mA, when connected to the unique integrating feature of the ETS range of irrigation controllers, automatically adjusts the set watering times to suit the growing environment.
The output current loop 0 - 20mA can be used as a °hour programmed start(s) for other controllers
Field tested on six commercial nurseries in HDC funded research (HNS 159, HNS 159A; reports available to levy-payers from the HDC), evaposensor control offers many advantages.
