Radar Type
River Water Level Transmitter

Radar Type River Water Level Transmitter measures water level by calculating the distance to the river surface using reflected microwave signals. Its non-contact operation ensures stable and reliable measurement under varying flow and environmental conditions. Also applicable to water levels in dams, tides, industrial and agricultural water facilities, regulating basins, sluice gates, water treatment facilities, retention ponds, etc. as well as river water level.

Provides stable measurement even under harsh environmental conditions such as storm, heavy rain, flow velocity, temperature variations, etc.

The non-contact measurement principle eliminates mechanical wear and prevents fouling from debris, sediment or biofilm, significantly reducing maintenance requirements.

The transmitter is installed above the water surface, allowing measurement without contact with the river, which improves safety and simplifies installation and inspection.

Radio Law of Japan Compliant Product.

Operating at 26GHz, it complies with low-power radio regulations by limiting electric field strength.

No radio license is required, ensuring safe operation even in open areas.

• Online River Water Level Monitoring & Flood Warning by Radar Type River Water Level Transmitter

Radar Type River Water Level Transmitter is a TOF (time-of-flight) based level transmitter and emits short microwave pulses toward the river water surface and measures the time-of-flight of the reflected signal to determine level.

The 26GHz operating frequency provides a moderate beam angle suitable for a wide range of liquid applications such as leve in rivers, dams, tides, industrial and agricultural water facilities, regulating basins, sluice gates, water treatment facilities, retention ponds, etc.

Its pulse-based measurement method offers reliable non-contact operation, stable echo detection and robust performance.
