Unique river construction utilization method! Unified management of upstream rainfall forecasts and on-site water levels!

Unique river construction utilization method! Unified management of upstream rainfall forecasts and on-site water levels!

For the construction industry: Innovative ideas and technical proposals! Centralized management of weather information and site water levels in the cloud!

Are you facing any of these troubles? The water level at the construction site rises rapidly due to rainfall in the upstream area during river construction. We manage weather forecasts and water level observations separately, making it difficult to issue evacuation instructions promptly. The challenges you are facing can be solved with Sysmet Co., Ltd.'s [Natural Disaster Prevention System ZEROSAI]. - Pinpoint weather forecasts for multiple upstream river areas - Centralized management of water levels at the construction site observed with [battery-operated water level gauges] on a dedicated website [Disaster Prevention Board]. *For more details, please visit our website 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.
