Crystal-type water level gauge "QS Series"

Crystal-type water level gauge "QS Series"

The construction method is easy, and maintenance is simple! A quartz 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 derives the water level from the oscillation frequency that varies accordingly, enabling high-precision measurements. Additionally, it eliminates conversion errors due to aging changes in components like diaphragms 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 in rivers, dams, reservoirs, and tide levels, offering excellent cost-effectiveness. 【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 document or feel free to contact us.

Optical Crystal Water Level Gauge "OPQS Series"

Optical Crystal Water Level Gauge "OPQS Series"

Using optical fiber for data transmission between the sensor and the converter! Achieving high-precision water level measurement.

We would like to introduce our optical quartz-type water level gauge, the "OPQS Series." The optical quartz-type water level gauge converts the frequency signal from the quartz oscillator into an optical signal (SM) at the E/O conversion section within the sensor and transmits it. This product has a built-in battery inside the sensor as its power supply. The quartz oscillator used in the water level measurement section changes its resonant frequency linearly in response to the applied water pressure, and since the rate of change is large, it enables highly accurate water level measurement. 【Features】 ■ High Precision: Utilizes the principle of the highly regarded quartz-type 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 the water level gauge, 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 resonance 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 level gauge sensor and five sensors within the sensor cable, totaling six temperature sensors. By performing density correction with a dedicated water level gauge recorder, it is possible to maintain high precision measurements 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 correction with six temperature sensors ■ Easy installation and maintenance ■ Temperature sensors built into the water level gauge sensor cable *For more details, please refer to the PDF document or feel free to contact us.

Crystal Water Level Gauge "HJ-509"

Crystal Water Level Gauge "HJ-509"

All-in-one monitoring observation system built with FOMA! Automatic distribution of scheduled emails and alarm emails.

The "HJ-509" is a quartz-type water level gauge equipped with self-recording, internet display, and email functions. It measures water pressure using a quartz pressure sensor at a sampling interval (typically 1.0 seconds) and records the data for the measurement duration on an SD card. It enables high-precision and stable water level observation, and also measures and records water temperature, air temperature, and atmospheric pressure as supplementary data. 【Features】 ■ Built-in internet communication function allows monitoring from anywhere via the FOMA network (DOCOMO) ■ High-precision water pressure measurement with automatic atmospheric pressure compensation using a vent pipe integrated cable ■ Can measure and record data (voltage input) from other devices equally ■ Uses an SD card (up to 32GB) for data memory ■ Data retrieval is quick and easy with just an SD card exchange *For more details, please refer to the PDF document or feel free to contact us.
