What is the unique aspect of the tension controlled irrigation of Tevatronic compared to conventional and other tensiometer in use?

Tevatronic tension controlled irrigation is autonomous, due to the integration of hardware and software developed by the company and the adoption of an appropriate method of operation.
Traditional tensiometers are analogs. The incorporation of pressure transducers into tensiometers enabled digital output,
continuous readings, processing the data and taking advantage of up to date communication for viewing the data.
The technology to couple tension readings to solenoid valves to initiate irrigation is already known for several decades.
More recently the ability to terminate the irrigation when a pre-set tension is reached, at the position where the tensiometer is located, was also introduced.
The next step of development was missing until Tevatronic developed a propriety algorithm that control precisely irrigation depth, independent of the tensiometer location.
The control of irrigation depth enabled a revolutionary change in the method of operation that finally transformed the system to fully autonomous:
initiating and terminating the irrigation without human intervention using shallow monitoring of tension combined with irrigation to any desired depth.
The Tevatronic system does not rely on statistical averaging of root density and soil variability, as common in other tension controlled irrigation systems,
but actively eliminate the root density variability (shallow monitoring) and bypass the existing soil variability (irrigation depth control).
