[NETIS Registration] Radio-type water level gauge for measuring water levels in rivers, ports, etc.

Adopting a non-contact radio type that is less affected by rain, wind, muddy water, and sediment! A radio water level gauge that solves the problems encountered with other types of water level gauges!!

The radar-type water level gauge measures the distance to the water surface by transmitting and receiving radio waves (microwaves), allowing for the measurement of water levels in rivers and seas. Since it measures water levels non-contact, it is less affected by rain (heavy rain), wind (storm), waves, and sediment, enabling continuous monitoring of water levels. It is compatible with sensitive weak wireless devices and can be quickly installed and measured in any desired monitoring location, indoors or outdoors. In recent years, with the frequent occurrence of river flooding due to sudden heavy rain and typhoons, it can also be used as a "crisis management-type water level gauge sensor." It measures water levels in rivers in real-time and alerts to sudden changes in water levels during heavy rain. ★NETIS Registered Product★ Registered in the 【NETIS】 New Technology Information Provision System operated by the Ministry of Land, Infrastructure, Transport and Tourism. <Registration Number: QS-200062-A> 【Features】 - Non-contact design prevents damage from collisions with floating debris and is not swept away by muddy currents. - No accumulation of debris or marine organisms, making maintenance easy. - Radar type is less affected by storms, heavy rain, and whitecaps. - Maximum measurement distance of 20 meters. - Safe measurement even in narrow waterways.

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

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

As sudden and localized disasters described as "the largest in recorded history" and "once in 50 years" occur, 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 the anticipated impacts, thereby achieving a solution that reduces not only the introduction 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 while on patrol.
