Submersible water level gauge

Submersible water level gauge

Submersible water level gauge

**Overview** The TD8000 series is a two-wire submersible level gauge that uses a high-precision semiconductor pressure sensor for water level detection. Despite its slim body, it has a built-in amplifier, eliminating the need for an external converter. The detection unit can be directly suspended in water or placed on the bottom, measuring the water head pressure on the diaphragm with the semiconductor pressure sensor, which converts it into a current signal for transmission. **Features** - Pressure detection type using a semiconductor pressure sensor - Built-in amplifier, two-wire (4-20 mA) - No need for a hanging chain as the wire is internally housed within the cable - Stable installation when placed on the bottom with a detection unit stand attachment - Built-in lightning protection circuit, resistant to lightning surges - TD8300 (high precision type, accuracy ±0.10% F.S.) - TD8200 (slim type, outer diameter Ø14mm) For deep wells Ø14mm with built-in amplifier.

Crisis management-type water level gauge solution that can remotely monitor flood risks.

Crisis management-type water level gauge solution that can remotely monitor flood risks.

Real-time centralized monitoring of water levels at multiple locations, such as rivers and ponds, where flood and inundation monitoring is necessary, while keeping introduction and operational costs low.

Amid the occurrence of sudden and localized disasters described as "the largest in recorded history" and "once in 50 years," monitoring of reservoirs and rivers is becoming increasingly important. Therefore, by installing measuring devices (monitoring posts) in more rivers, we have combined the latest technologies such as ICT and IoT with existing elemental and general-purpose technologies to accurately grasp flood situations and quickly and accurately understand potential future impacts, achieving a solution that reduces not only the initial implementation costs but also the TCO (total cost of ownership). The measurement data collected from the devices is uploaded to the cloud via LoRaWAN, and when thresholds are exceeded, notifications are sent to registered email addresses. Additionally, it is possible to monitor in real-time through a web browser and download measurement values, allowing for the confirmation of multiple sensor readings from a distance. This not only reduces the time staff need to physically visit locations at risk of flooding during heavy rain or earthquakes but also eliminates the risk of staff being affected during patrols.

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.
