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.

Mechanism of localized heavy rainfall occurrence <Materials being presented>

Mechanism of localized heavy rainfall occurrence <Materials being presented>

Not just linear precipitation zones? By understanding signs and trends, we can detect indications more quickly.

I will introduce the "Mechanism of Localized Heavy Rainfall." When a large amount of warm, moist air flows into the lower atmosphere, along with the inflow of cold air aloft, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. As cumulonimbus clouds form successively in the same location and move eastward, they create a linear precipitation zone, resulting in sustained heavy rainfall in the same area. The related catalog provides a more detailed explanation of why localized heavy rainfall occurs, incorporating examples from the heavy rain event in northern Kyushu. Please take a look. [Development and Continuation of Cumulonimbus Clouds] - When a large amount of warm, moist air flows into the lower atmosphere, along with the inflow of cold air aloft, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. - As cumulonimbus clouds form successively in the same location and move eastward, they create a linear precipitation zone, resulting in sustained heavy rainfall in the same area. *For more details, please refer to the PDF document or feel free to contact us.

Rope-type water level gauge WL50 (Alpha Optical) rental

Rope-type water level gauge WL50 (Alpha Optical) rental

When the sensor attached to the end of the rope touches the water, it activates and sounds a buzzer, allowing us to determine the water surface position using the scale on the rope at that moment.

***Features*** - By using a lightweight measuring rope and processing the rope's cross-section to be more compact than conventional products, it has become less susceptible to the effects of surface tension from water droplets inside the boring pipe. - By mixing copper wire with traditional stainless steel wire, signals are transmitted more accurately from the electrode to the buzzer. - No grounding required. - This type alerts water levels with an electronic sound. - Made with strong stainless steel wire, it will not easily break unless excessive force is applied (load capacity approximately 120kg, according to the manufacturer) (minimum scale 1cm). - The rope-type water level gauge has been improved from a traditional reel case to a plastic one, making it more compact and lightweight. - The battery replacement has been improved for one-touch operation.
