Installation and Adjustment of a Hydraulic Evapotranspiration Multisensor Prototype

The aim of this note is to provide a quick overview of the installation and adjustment of an exclusively mechanical standalone automatic device that self-adjusts to weather changes to control the frequency and duration of the irrigation. The hydraulic evapotranspiration multisensor (HEM) is composed of a reduced evaporation pan with water, a magnet with a floater floating in the pan, a hydraulic device operated by a magnetic hydraulic valve that has the ability to adjust the frequency of irrigation, and a hydraulic system that returns water to the pan during each irrigation event through an adjustable dripper to replace the water lost due to the fact of evaporation. This note is particularly relevant for arid-semi-arid regions where agricultural production is fully dependent on irrigation.

Automated summary

The aim of this note is to provide an overview of the installation and adjustment of a mechanical standalone automatic device that adjusts irrigation frequency and duration based on weather changes. The hydraulic evapotranspiration multisensor (HEM) consists of an evaporation pan, a float with a magnet, a hydraulic device with a magnetic hydraulic valve for adjusting irrigation frequency, and a hydraulic system for replenishing water lost through evaporation. This note is particularly relevant for arid-semi-arid regions with irrigation-dependent agriculture.
