Water Level Monitoring Sensor Applications
Working on Water
Senix ToughSonic® Ultrasonic Transmitters are a reliable and cost-effective solution for water monitoring, both indoors and outdoors.
Rugged for use in harsh ocean environments; 316 stainless steel, fully potted electronics, IP68 rating, and smart to provide reliable calculations in these challenging and fluid environments.
Featuring “non-contact” technology that looks down at the water surface from above, these sensors can be used in open air applications or in “stilling” tubes that focus the sound to avoid obstacles and improve performance.
Thousands of Senix ToughSonic sensors are installed in water projects across the globe, including; tank level monitoring, irrigation, stream monitoring, sea level monitoring, and flood and tsunami warning systems.

Water Monitoring Application Stories
The Sensors
Whether used indoors or out, ToughSonic® sensors can take abuse. Solid state electronic components are epoxy potted into stainless steel housings, and there are no mechanical parts to break. IEC compliant electrical interfaces are protected from reversed connections and over-voltages.
These distance measurement sensors connect with all common types of automation and telemetry equipment. Applications range from simple analog connections to sophisticated multi-sensor data networks. Our sensors are cost effective because flexible connectivity is embedded in the sensor’s software – power that you can unlock with the SenixVIEW PC software included with every sensor. Push-button “teach” is also included in many models.

Irrigation
Historically, farm water was controlled manually.
But there’s a better way…
ToughSonic® ultrasonic sensors are used to measure the level of channels, canals and gates to control the distribution of irrigation water. The sensors connect with SCADA and telemetry systems to control the flow of water. Or they can be connected directly to a pump and let the sensor throttle the flow of water based on the level readings it is taking.
Senix sensors are used worldwide by municipalities, irrigation districts, water providers, water associations, and backyard enthusiasts.
Murray Irrigation, Australia’s largest private environmental and irrigation water delivery company, uses the ToughSonic 14 to manage water distribution to many of their approximately 2,200 landholdings throughout southern New South Wales. Customers on their PIIOP program can order, sell and buy water from their cell phone using telemetry-enabled, automated and/or remote-controlled technology. See our article on this project.

Remote Monitoring
Open Channel Flow
Open Channel Flow measurement determines the volume of water, effluent or industrial waste flowing through a channel, flume or weir. Flumes and weirs are hydraulic structures within which the liquid flow rate is determined by measuring the height of the liquid flowing through the structure. That height is converted to flow using an equation specific to the structure. Positioned at the required location, ToughSonic sensors measure the liquid height by non-contact distance measurement looking down at the liquid surface.
- An example Parshall flume drawing is shown at the right.
- Typical weirs are shown below.
- The flow rate through the weir can be controlled by adjusting the vertical position of a gate.

Flood Monitoring
Senix ToughSonic® sensors measure the level of water flowing in streams and rivers. Sensors mounted on bridges, poles, and other structures look down at the water to report flood status.
The Iowa Flood Center (IFC) was formed in 2009 to engage in flood-related projects to help Iowans understand their flood risks and make better decisions. In 2010 they chose ToughSonic sensors for their new Iowa Flood Information System (IFIS) and over several years that system has added over 200 monitoring sites using ToughSonic 50 sensors. Please see our article on the IFIS system for additional information.
In 2015, Senix sensors were selected to monitor typhoon storm surge flooding in the Philippines. Here is a short video on the Philippines Flood Warning System
