Efficient irrigations by means of OTT – Adcon Telemetry equipment distributed by BEIA Consult International Bucharest
Provide the crops with exactly as much water as the really need – neither more, nor less. It always was and still is the problem of irrigation systems that OTT – Adcon Telemetry can help you to optimally solve. And can do it for all types of climate regimes and for an impressive number of crops, based on either evapotranspiration measurement or soil moisture measurement. The diagram below, for example, shows a comparison over four days of June 2014, when total evapotranspiration was 16.06 mm, while total rainfall was 7.2 mm only.
The primary information necessary for a comparison like the one in the figure is gathered by appropriate sensors directly connected to the Adcon remote telemetry unit (RTU). From the RTU, information goes through UHF radio, through GSM-GPRS or even UMTS to the central server, which is able to provide accurate data characterising the water needs of the crop. The server puts this data on the Internet, so that the grower can have it anytime and in any location provided with Internet access. Grower’s decision to change the irrigation regime (start, stop, modify) can be returned by the system to the RTU, which does have the driver electronics able to act upon the irrigation valves.
An important note is that the central server and the software specific to irrigations control are resources that Beia Consult can remotely offer to growers against a modest subscription fee. Acquisition and exploitation of these relatively expensive and demanding resources by the growers themselves could otherwise be justified only by a very great number of RTUs, by strict confidentiality requirements or by other such restrictive conditions.

All above-specified sensors can be directly connected to Adcon RTUs able to transmit and receive information by UHF radio or by the GPRS data service offered by all mobile telephony providers. Adcon RTUs are also able to control the electric latching valves of any irrigation system.
The Adcon Telemetry addSWITCH A724 RTU
A724 addSWITCH is the RTU specially created by Adcon Telemetry for the remote control of irrigation systems. It can distinctly control of up to 4 solenoid latching valves, it can receive data from up to 4 water flow meters and from one manometer continuously measuring pressure in the watering installation.
