Crystal-type water level gauge "QS Series"

Crystal-type water level gauge "QS Series"

The construction method is easy, and maintenance is simple! A crystal-type water level gauge that allows for clock calibration using GPS.

The "QS Series" is a pressure-type water level gauge that utilizes quartz oscillators, which serve as the frequency standard for clocks and communication devices. It applies water pressure, which changes with the water level, to the quartz oscillator, and obtains the water level from the oscillation frequency that varies accordingly, enabling high-precision measurements. Additionally, it eliminates conversion errors due to aging changes in diaphragms and other components commonly found in traditional pressure-type water level gauges. With a measurement range of 10m to 70m using a single sensor, it is suitable for use not only in rivers but also in dams, reservoirs, and tide levels, offering excellent economic efficiency. 【Features】 ■ Maximum accuracy of 0.01% F.S. High precision and reliability from quartz oscillators ■ Easy installation on embankments and structures ■ Simple maintenance management ■ GPS (optional) for clock calibration *For more details, please refer to the PDF materials or feel free to contact us.

Pressure-type water level gauge "CPS-A Series"

Pressure-type water level gauge "CPS-A Series"

Robust design using stainless steel! A compact and lightweight pressure-type water level sensor that is easy to handle.

The "CPS-A Series" is a pressure-type water level gauge that utilizes a semiconductor pressure detection method (capacitive type). It detects the water pressure that changes with the water level using a pressure-sensitive element, converts it into an electrical signal, and measures the water level. The pressure-sensitive element is made of ceramic, which offers excellent temperature characteristics, vibration resistance, and environmental durability. Additionally, its compact and lightweight design makes installation and maintenance easy, allowing for a wide range of applications. 【Features】 ■ Compact and lightweight pressure-type water level sensor that is easy to handle ■ Built-in lightning protection board, resistant to lightning ■ Robust design using stainless steel material *For more details, please refer to the PDF document or feel free to contact us.

Radio Wave Water Level Gauge "MIR-1"

Radio Wave Water Level Gauge "MIR-1"

A simple, compact, and lightweight design! Stable measurements can be made without being affected by environmental factors such as temperature.

The "MIR-1" is a radio wave level gauge that measures pulse propagation time. Since it uses microwaves for measurement, it is not affected by environmental conditions or the temperature of the measurement target, allowing for stable water level measurement in rivers and similar environments. The intensity of the microwaves used in this device is classified as weak radio waves, which are not subject to radio law regulations, meaning it does not affect the human body or the environment, and there are no restrictions on where it can be used. 【Features】 ■ Stable measurements unaffected by environmental factors such as temperature ■ Uses weak radio waves that do not impact the human body or the environment ■ Simple, compact, and lightweight design (integrated transmitter and antenna) ■ Capable of non-contact measurement even in harsh environments such as debris flow hazard streams *For more details, please refer to the PDF document or feel free to contact us.

Laser Scanning Water Level Gauge "LSW Series"

Laser Scanning Water Level Gauge "LSW Series"

Reduce the impact of environmental factors such as fog and rain! Non-contact water level gauge that detects water levels using infrared laser.

The "LSW Series" is a laser-based non-contact water level meter that measures distance by irradiating an infrared laser onto the measurement surface, allowing for water level measurement. By scanning the infrared laser and capturing the water surface as a plane, it can reduce environmental impacts such as rain and fog compared to conventional products. The measurement accuracy is ±1cm, and the protection rating is IP53 (dustproof and rainproof). 【Features】 ■ Non-contact water level meter that detects water levels using infrared laser ■ Scans laser light to measure the detection water surface at multiple points ■ Excludes outliers from multi-point measurement data and performs averaging to reduce the impact of environmental factors such as fog and rain *For more details, please refer to the PDF document or feel free to contact us.

Optical Crystal Water Level Gauge "OPQS Series"

Optical Crystal Water Level Gauge "OPQS Series"

Using optical fibers for data transmission between sensors and converters! Achieving high-precision water level measurement.

We would like to introduce our optical quartz water level gauge, the "OPQS Series." The optical quartz water level gauge converts frequency signals from a quartz crystal oscillator into optical signals (SM) within the sensor's E/O conversion section for transmission. This product has a built-in battery inside the sensor to serve as the power supply for the sensor. The quartz crystal oscillator used in the water level measurement section changes its resonant frequency linearly in response to the applied water pressure, and due to the large rate of change, it enables highly accurate water level measurement. 【Features】 ■ High Precision: Utilizes the principle of the highly regarded quartz water level gauge for accurate water level measurement. ■ Lightning Protection: Uses optical fiber for data transmission between the sensor and the converter. *For more details, please refer to the PDF document or feel free to contact us.

Water temperature compensated crystal type water level gauge "QSR Series"

Water temperature compensated crystal type water level gauge "QSR Series"

Achieves high-precision and stable water level measurement. The construction method is easy, just like with water level gauges, and maintenance management is also simple.

The "QSR Series" is a pressure-type water level gauge that utilizes a quartz crystal oscillator. The quartz crystal oscillator changes its resonant frequency linearly in response to the applied water pressure, and due to its large rate of change, it enables high-precision and stable water level measurement. The quartz water level gauge with temperature compensation measures water temperature using one temperature sensor inside the water level gauge sensor and five sensors within the sensor cable, totaling six temperature sensors. By performing density compensation with a dedicated water level gauge recorder, it is possible to maintain high precision even in cases where the water depth is deep, such as in dams, and there are temperature differences in the water. 【Features】 ■ High precision and stability ■ Elimination of density difference effects ■ Water temperature measurement and density compensation with six temperature sensors ■ Easy installation and maintenance ■ Temperature sensors integrated into the water level gauge sensor cable *For more details, please refer to the PDF materials or feel free to contact us.
