Remote Irrigation Channel Water Level Monitoring

Frequently Asked Questions

How does the Remote Irrigation Channel Water Level Monitoring Solution measure canal water height from an operational standpoint?

The Remote Irrigation Channel Water Level Monitoring Solution utilizes an 80 GHz millimeter-wave non-contact radar sensor mounted above the open water surface on a bridge, gantry, or channel arm. The sensor emits high-frequency radar pulses down toward the fluid surface and calculates the exact distance based on the reflected signal return time. The internal processor converts this distance into accurate water depth and bank headroom metrics, packages the data into an encrypted payload, and broadcasts it wirelessly via LoRaWAN® or NB-IoT/LTE-M. The telemetry is instantly ingested by the Ellenex Software Platform for real-time visualization and alerting.  

How do I install the Remote Irrigation Channel Water Level Monitoring Solution over an open irrigation canal?

Installation is straightforward and requires no specialized mounting tools, extra power cabling, or field programming. Field personnel simply attach the mounting bracket to an overhanging structure—such as a footbridge, headgate frame, culvert arch, or dedicated mounting pole—ensuring the radar face points perpendicularly toward the water surface. The IP68 UV-stabilized transmitter housing is secured nearby in a location receiving clean wireless reception. Once turned on via its internal switch, the factory pre-configured sensor automatically registers with the Ellenex Software Platform and begins transmitting live readings.  

Does aquatic weeds, floating moss, or turbulent water affect the radar accuracy of the Remote Irrigation Channel Water Level Monitoring Solution?

No. A major advantage of 80 GHz radar technology is its complete immunity to surface vegetation, floating debris, silt, and turbulent flow. Unlike submerged pressure transducers that clog with weed growth, or ultrasonic sensors that lose echo locks in high winds or turbulent foam, the narrow 80 GHz radar beam passes cleanly through foam and measures true liquid surface elevation with millimeter precision.  

Can the Remote Irrigation Channel Water Level Monitoring Solution calculate open-channel volumetric water flow rates?

Yes. When installed over standardized hydraulic structures—such as Parshall flumes, V-notch weirs, broad-crested weirs, or calibrated canal cross-sections—the Ellenex Software Platform uses its formula configuration engine to convert raw stage height readings into volumetric flow rates. By assigning site-specific discharge rating curves to the sensor profile, operators gain continuous flow rate tracking without buying expensive acoustic Doppler velocity meters.  

How do automated alerts work on the Ellenex Software Platform if an irrigation canal risks overflowing or running dry?

The Ellenex Software Platform features a fully customizable multi-channel alert engine. System administrators can set dynamic threshold boundaries for every channel site, such as a "High-Level Spill Alert" when water approaches bank-full height, or a "Low-Flow Alert" if a headgate closes unexpectedly. When a threshold is crossed or water levels change at an abnormal rate, the platform dispatches real-time alerts via SMS, email, or mobile app push notifications to on-call ditch riders and water managers.  

How does weather exposure affect the long-term durability of the Remote Irrigation Channel Water Level Monitoring Solution?

The solution is built specifically for extreme rural weather conditions. The radar sensor face and transmitter enclosure are fully sealed to IP68 standards and housed in UV-stabilized materials resistant to sun degradation, heavy rain, dust storms, and extreme temperatures. Because there are no moving parts and the device never contacts channel water, internal condensation and corrosion risks are completely minimized.  

What routine maintenance is required for the Remote Irrigation Channel Water Level Monitoring Solution over its operating life?

The system is practically maintenance-free. It operates on an internal, replaceable 3.6V Lithium primary battery combined with ultra-low-power firmware management. It requires no external solar panel cleaning, battery charging, or sensor descaling. Configured on the Ellenex Software Platform for standard agricultural reporting frequencies (such as 15-minute or 1-hour updates), the internal battery delivers an operational lifespan of up to 10 years before requiring replacement.
