Open-channel irrigation water intakes can be monitored for water level / flow and they can be optionally controlled by opening and closing a gate to deliver programmed flow.
This technology can save water and cost of water and can eliminate the hands on requirements of a manual system. Such systems enable irrigators to monitor and control the water they are allowed to take from rivers and streams for irrigation. These range from basic monitoring-only to an automated and telemetered solution, where irrigators can access their system remotely via the Internet using a Smartphone, as if they were at the site.
The simplest option is monitoring-only. However many clients opt for full automation – with automatic gate control – which reduces the need to carry out manual tasks such as adjusting gates an downloading data.
A typical system is comprised of these interlinked parts:
• A flow measurement section, a weir/flume fitted with a water sensing structure
• A Neon Remote Terminal or Module for logging data and optionally, transmitting it.
• An optional inlet gate structure with gate control system
In the basic monitoring system, the abstracted flow is measured and recorded by 6541 Precision Water Level Instrument. This option may be sufficient where there is no gate control or when an irrigator is happy to control the flow with a manually-operated gate and periodically download flow data.
In an automatic monitoring system, a control gate automatically adjusts its position to maintain the flow within a user programmed target range. The gate controller receives flow rate information from the flow measurement instrument and compares it with the target. If the flow is lower than the target the controller increases the gate opening to increase the flow and vice versa. The gate controller adjusts the gate to keep the flow on target. Because the Neon system is Internet-capable it also enables you to monitor the site and allows you make changes to the flow target, without having to visit the site.
It allows you to view activity, data and to change flow settings via the Internet, saving time and reducing operational costs. Telemetry of data, between the site and the Neon server, is possible anywhere there’s cellular or satellite coverage at the site.
Neon provides a window on your irrigation monitoring system. You can check it remotely at any time, or change flow targets (for sites with flow control gates), by viewing secure data from your telemetered sites over the internet. And you don’t have to do this from your desktop computer. Your Android Smartphone can provide a mobile view of flow and gate control status, wherever there’s cellular coverage. If your site has a control gate, you can also use your phone to change the flow. If ‘out-of-range’ flows or other malfunctions should occur, with telemetered sites, you can receive programmed alarms via text or email.
Any required flows can be programmed allowing irrigators to set exact flow requirements. The weir is usually hydraulically coupled to the stilling well. The Neon Remote Module converts water level from the sensor to flow rate.
It also provides feedback for the gate controller and can be accessed by a standard web browser.
