Ultrasonic water level gauge

Ultrasonic water level gauge

Open waterways, small rivers, and reservoirs! Suitable for relatively low-lying areas close to the water surface.

The "Ultrasonic Water Level Gauge" is a product that emits ultrasonic waves and observes the water level based on the time it takes for the reflected ultrasonic waves to return to the transmitter. It can safely measure in locations where submerged pressure sensors are difficult to install or where water quality characteristics have an impact. It is suitable for relatively low locations such as open channels, small rivers, and reservoirs. We offer three types: TYPE 1, which allows measurement and display with only the sensor unit; TYPE 2, where the sensor unit and control display unit are separated (connected by cable); and TYPE 3, which transmits data measured by the sensor wirelessly to the display unit. 【Features】 <TYPE 1> ■ Measurement and display possible with only the sensor unit, ■ Continuous measurement and display while power is supplied. <TYPE 2> ■ Sensor unit and control display unit are separated (connected by cable). *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] River Upstream Water Level Measurement - Radio Wave Water Level Meter

[Case Study] River Upstream Water Level Measurement - Radio Wave Water Level Meter

For monitoring river flooding! A water level gauge that detects flooding by capturing sudden changes in river water levels.

We introduce a case study of the radio wave water level gauge handled by Matsushima Majatech, which has been implemented in upstream rivers. This product detects rapid changes in river water levels and alerts to potential flooding. It can respond to extreme water level changes of about 5 meters in approximately 2 seconds. Microwaves have the property of penetrating steam, allowing for stable detection of the water surface even during fog, storms, or heavy rain. Since it measures the water surface non-contact, it can operate without collision or damage even when sediment or driftwood flows by. 【Case Study】 ■ Implementation Location ・River ■ Implemented Product ・Radio wave water level gauge

[NETIS Registration] Radio-type Sensor for Crisis Management Water Level Gauge (Radio Water Level Gauge)

[NETIS Registration] Radio-type Sensor for Crisis Management Water Level Gauge (Radio Water Level Gauge)

The crisis management water level gauge with a radio wave sensor reliably observes even during heavy rain, strong winds, and muddy flows! Since it is non-contact, there are no failures due to collisions with debris flows!

Flooding of rivers due to heavy rain causes significant damage to our lives and livelihoods. Radar level sensors are less affected by storms, allowing for accurate detection of rapid water level changes, which can aid in flood prediction. Radar water level gauges measure the distance to the water surface by transmitting and receiving radio waves (microwaves), allowing for the measurement of water levels in rivers and seas. Since they measure water levels non-contact, they are less influenced by rain (heavy rain), wind (storms), waves, and sediment, enabling continuous monitoring of water levels. They are also compatible with weak wireless devices of concern and can be quickly installed and measured in any desired monitoring location, indoors or outdoors. ★NETIS Registered Product★ Registered in the new technology information provision system 【NETIS】 operated by the Ministry of Land, Infrastructure, Transport and Tourism. It is the "first in the country" registered technology as a radar water level gauge. <Registration Number: QS-200062-A> For more details, please click on the related link or download the catalog.
