Radio wave velocity water level gauge

Radio wave velocity water level gauge

Since the water level can be measured simultaneously at the same location, high-precision flow calculation is possible!

We would like to introduce our "Radio Wave Velocity Water Level Gauge." It measures the surface flow velocity and water level of rivers using non-contact, angled irradiation. The direction of irradiation can be adjusted to 45 degrees to the left and right in the horizontal direction (azimuth) relative to the river surface, allowing for flexible adaptation to changes in the riverbed after flooding. Additionally, it is compliant with specific radio equipment standards. 【Features】 ■ Simultaneous observation of flow velocity and water level with a single transmitter ■ Non-contact, angled irradiation allows installation in locations that were previously difficult to access ■ Improved functionality with irradiation distance increased from 20m to 30m compared to our conventional models *For more details, please refer to the PDF document or feel free to contact us.
