Ultrasonic water level meter

Measure water level non-contact on the water surface! Data recorded in the built-in memory can be printed with a specified period.

We would like to introduce our "Ultrasonic Water Level Meter." This water level meter is suitable for measuring in rivers where sediment and debris flow, rivers with frequent bed changes, high water levels, high flow rates, and corrosive water quality. It comes standard with BCD output compliant with the Ministry of Land, Infrastructure, Transport and Tourism's Telecommunications Specification No. 54, and the measured water level data can be easily retrieved using a USB memory stick. 【Features】 ■ Standard BCD output compliant with the Ministry of Land, Infrastructure, Transport and Tourism's Telecommunications Specification No. 54 ■ Measured water level data can be easily retrieved using a USB memory stick ■ Data recorded in the built-in memory can be printed for specified periods *For more details, please refer to the PDF document or feel free to contact us.

Crisis management type water level gauge

Our company, with many years of experience and proven results, offers products utilizing river observation technology!

We would like to introduce our "Crisis Management Type Water Level Gauge." This product is a water level observation device that complies with the observation standards and specifications of the Ministry of Land, Infrastructure, Transport and Tourism's crisis management type water level gauge. As of April 2024, we have delivered approximately 2,200 units nationwide. With the remote setting function, operational parameters (observation start water level, observation cycle) can be obtained from the upper server during health monitoring or at the timing of hourly data transmission. This allows for changes to operational parameters without the need to visit the site, saving time and costs. 【Features】 ■ Operational parameters can be changed remotely even in autonomous mode ■ Enhanced logger function allows for storage of observation data for over three months *For more details, please refer to the PDF document or feel free to contact us.

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 Meter." 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 horizontally (azimuth) relative to the river surface, allowing for flexible adaptation to changes in the riverbed after flooding. Additionally, it complies 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.

Radio wave water level gauge

Since it can be installed on bridge piers and other structures that are not affected by high water levels, maintenance is easy!

We would like to introduce our "Radio Wave Level Gauge." Since it can measure non-contact, it can safely measure even during high water levels. Due to the use of weak radio waves, a radio station license is not required. Because it measures using microwaves, it can measure without being affected by rain, snow, or fog. 【Features】 ■ Non-contact measurement ■ Flexible usage environment conditions ■ No temperature correction needed ■ No radio station license required *For more details, please refer to the PDF document or feel free to contact us.

Optical Transmission Crystal Water Level Gauge

High lightning resistance and noise resistance through optical fiber transmission! Identification of fault locations through self-diagnosis function.

We would like to introduce our "Optical Transmission Crystal Water Level Gauge." It has a function to detect fiber optic disconnections, and when a disconnection is detected, it automatically stops the laser output immediately. The transmitter uses a high-precision, high-stability quartz crystal oscillator. By using a water temperature sensor in conjunction, it corrects water density based on water temperature, enabling more accurate water level measurements. 【Measurement Range】 ■0–10m ■0–20m ■0–50m ■0–100m *For more details, please refer to the PDF document or feel free to contact us.
