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.

[Useful Information] Battery-powered water level gauge: Easy relocation to appeal to clients!!

[Useful Information] Battery-powered water level gauge: Easy relocation to appeal to clients!!

Introducing the benefits of battery-operated water level gauges! Easy relocation enhances the image for clients! Also serves as material for technical proposals and creative ideas!

The battery-operated water level gauge is an option for the 【Disaster Prevention System ZEROSAI】 with NETIS registration number QS-150021-VE. It has achieved easy installation and relocation compared to conventional products. Traditional water level gauges required a 100V commercial power supply or a solar power system. As the name suggests, the battery-operated water level gauge runs on batteries, allowing for installation anywhere as long as there is a 4G connection. It can be easily relocated to prevent flooding when river water levels are expected to rise rapidly or before a typhoon! The observed information can be centrally managed along with various weather data for comprehensive situational awareness. Unlike traditional models, which made relocation and removal difficult due to the solar power systems, this gauge allows for easy relocation and removal, enhancing the image for clients! It also serves as a great promotional tool for technical proposals and creative ideas! Please feel free to download the materials and make use of them.

Civil engineering measurement equipment Water level gauge (probe type) NA-WF

Civil engineering measurement equipment Water level gauge (probe type) NA-WF

It observes the water level, converts it into an instrumentation current signal, and outputs it.

The probe-type water level gauge observes the water levels of rivers, lakes, groundwater, waterways, dam leakage, residual water, etc., and converts them into instrumentation current signals for output. The detector is suspended from the water surface by a single coated stainless steel wire and detects contact with the water surface by moving up and down with a motor. The detection signal corresponding to the change in water level transmits the rotation of the measurement pulley through a relay circuit to the signal conversion section from the potentiometer, outputting an electrical signal (DC 4-20mA) as water level data. 【Features】 ○ Observes water levels and converts them into instrumentation current signals for output ○ The detector detects contact with the water surface by moving up and down with a motor ○ Sampling is possible within 10 seconds to 1 minute due to interval timer operation ○ Measurement range: 0 to 400 mm ○ Dimensions: φ300×285 mm, pulley diameter approximately φ160 mm For more details, please contact us or download the catalog.
