The EC-130 is a system that diagnoses whether the waterproof sheet is functioning safely and detects any leakage from damaged areas in the event of a breach, identifying the location of the leak. Since the detection unit is fixed, there is no need for moving operations, and measurements can be automatically conducted by a computer, allowing for the visualization of measurement results, making it easy to identify leak locations. Detection occurs very close to the waterproof sheet, so there is minimal impact from waste. 【Features】 ■ Easy to construct by simply laying it out at equal intervals above and below the waterproof sheet ■ The number of cleaning electrodes can be freely increased or decreased according to the scale of the disposal site ■ Minimal impact from waste due to detection occurring close to the waterproof sheet ■ No moving operations required for measurements ■ Automatic measurements by computer *For more details, please refer to the PDF document or feel free to contact us.

The "water-level type settlement gauge and inclinometer" is a system for observing the deformation of structures such as tunnels and bridge piers. The "water-level type settlement gauge" connects a reference water tank and the water-level type settlement gauges at each measurement point through a connecting water pipe, automatically measuring the settlement and uplift of the structure based on the water level. Additionally, the "inclinometer" measures the tilt of the installed structure relative to the vertical. 【Features】 <Water-level type settlement gauge> Connects the reference water tank and the water-level type settlement gauges at each measurement point through a connecting water pipe, measuring the settlement and uplift of the structure based on the water level. <Inclinometer> Measures the tilt (angle) of the installed structure. Uses a differential transformer type sensor for high precision and excellent durability. *For more details, please refer to the PDF document or feel free to contact us.

The "IoT Water Level Gauge (Crisis Management Type Water Level Gauge)" is a water level gauge for river flood countermeasures. Sakata Electric handles the water level gauge, control and power supply, while NTT Docomo is responsible for communication technology and cloud technology. In December 2017, it received an evaluation for compliance with technical specifications from the Ministry of Land, Infrastructure, Transport and Tourism. The water level gauge can be selected from three types suitable for rivers: "Hydraulic," "Ultrasonic," and "Radio." Notifications are sent via email when the warning water level is exceeded or when there is a device malfunction, and water level data can be checked daily. 【Water Level Gauge Lineup】 ■ Hydraulic Gauge ■ Ultrasonic Gauge ■ Radio Gauge *For more details, please refer to the PDF document or feel free to contact us.
