Radio wave water level and flow velocity meter 'RT720/RT720F-4VD4W'

The flow rate sensor operates within the 24.2GHz band at 10mW or less, and no wireless license is required for use! (Technically compliant product)

The "RT720-4VD4W / RT720F-4VD4W" is a device that combines a non-contact water level gauge, which measures the distance from the sensor to the water surface using radio waves, and a non-contact flow meter that measures flow velocity using microwave Doppler technology. The water level sensor operates in the 26GHz band and does not require a wireless license for use. Additionally, measurement intervals can be as short as one minute. 【Features】 ■ The flow velocity sensor can be used from a bridge at a distance of about 10 meters above the water surface in open channels and urban rivers. ■ Non-communication data is recorded on a 1GB SD card. ■ Communication data is recorded on a cloud server and an SD card. ■ No electrical or communication construction is required (uses solar power and 3G/4G communication). ■ Usable in areas such as rivers and waterways. *For more details, please download the PDF or contact us.

Portable Wave Velocity Meter "RYUKAN"

Supporting the safety and stability of high water flow measurements! Adopted as a standard method in the River Disaster Prevention Technical Standards (Survey Edition).

"RYUKAN" is a portable flow velocity meter that is small, lightweight, and powered by an internal battery. It can be mounted on a surveying tripod and does not require any special installation work. It has a built-in automatic angle correction function, eliminating the need for measurements with a level. Additionally, its small size and battery operation provide excellent mobility, enhancing the safety of flow observations and achieving labor savings. 【Features】 ■ Measures flow velocity from a distance without touching the water ■ Small and lightweight, making it easy to transport and install ■ Simple operation requiring no specialized knowledge ■ Automatic measurement for safe and stable observations even in bad weather ■ Continuous measurement captures sudden changes ■ Pre-installation ensures no missed flood peaks *For more details, please refer to the PDF document or feel free to contact us.

Radio wave flow meter (RQ-30 series)

Non-contact 24-hour flow velocity observation of rivers and waterways is now possible! A compact and energy-efficient flow meter. Water level observation is also completed with a single unit, and flow rate is calculated and output internally.

The RQ-30 is a radar sensor developed by the Austrian company Sommer that continuously measures the flow rate of rivers and waterways. It is a device that integrates two non-contact radar sensors that measure surface flow velocity and water level (certified for technical compliance). Due to its non-contact measurement, the system is not affected by damage from sediment or floating debris. For example, even in flood situations, it requires little maintenance and provides high reliability. It is equipped with a learning function that effectively removes measurement noise caused by rain and the terrain of the site. The lower limit for detection and measurement is very small at 0.1 m/s, allowing for the measurement of gentle flows. The distance to the water surface ranges from 0.5 m to 30 m (with 35 m and 15 m models also available), accommodating a wide range of measurements from small waterways to large rivers. Its low power consumption makes continuous operation in off-grid environments easy.
