Remote Water Level Measurement

Senix ultrasonic sensors are used in highly sophisticated environmental and industrial applications that measure remote bodies of water: ponds, streams, canals and even oceans. These systems typically involve remote, solar-powered ultrasonic level sensors transmitting measurements to centralised management system via cellular, satellite or radio communications. ToughSonic sensors provide the accuracy, long-term durability, digital communications and rapid time-to-first-measurement speed that makes remote water level measurement systems practical.

Irrigation Management

Severe drought and population growth are prompting unprecedented investment in the automation of irrigation distribution systems. Traditional infrastructure, including manual gates and mechanical water level measurement, cannot provide the accuracy or control necessary to reduce waste and fairly distribute scarce water resources to industry and the environment. Automated irrigation management systems use ultrasonic sensors to accurately measure and transmit water level and flow data via advanced computer networks. That data drives automated irrigation gates, pumps, valves and other infrastructure to precisely manage water distribution.

For example, water level sensors positioned on either side of an automated irrigation gate allow for precise water releases based on real-time level data. Releases can be triggered from command centres far from the actual gate. Similarly, water level sensors mounted over weirs transmit accurate water flow measurement. Tributary streams and rivers upstream of irrigation systems are often monitored by ultrasonic level sensors in order to predict the total water resources coming into a system for distribution.

Flood Monitoring

As extreme flooding events are becoming increasingly common around the world, ultrasonic level sensors are being used in sophisticated networks to monitor streams and rivers in areas prone to flooding. Real-time water level data feed advanced hydrologic models to predict peak flood levels and timing. Accurate advance warning of flood levels can save lives and reduce disaster management costs.

Weather Modelling and Forecasting

Weather research and water resource forecasting rely, in part, on the accurate monitoring and modelling of water, snow and ice levels. Remote weather stations equipped with non-contact ultrasonic sensors measure water levels in warmer months and snow and ice levels in colder months.

Ultrasonic water level sensors are also used in coastal areas to provide real time monitoring of sea level and tidal action. Sensors mounted on piers or over coastal bridges can detect storm surges and even Tsunamis before they hit population centres.
