Ultrasonic sensor for remote water level measurement

April 2016 Level Measurement & Control

As both droughts and floods become more common around the world, sophisticated water level monitoring systems are being deployed. Advanced ultrasonic sensors are critical components of these new systems. Specialist distance measurement manufacturer, Senix has introduced the ToughSonic remote 14 ultrasonic level sensor, the first in a series of ultrasonic water level sensors designed specifically for remote monitoring applications. The ToughSonic remote 14 and the soon to be released ToughSonic remote 30 and remote 50 are designed specifically for these demanding applications.

Irrigation districts are automating operations to control the allocation of precious water to farms and industry more precisely. Remote water level sensors transmit real-time level data to centralised computer systems that allow managers to control flood gates remotely. Flood monitoring systems monitor stream and river levels, watching for sudden rises that predict flooding downstream. Remote water level sensors powered by solar panels and connected by radio, cellular or even satellite communications provide the data that drives these systems.

The ToughSonic remote 14 is a digital, surge-protected version of the ToughSonic 14, one of the most popular remote water level sensors, and consumes even less energy. This stainless steel, IP68-rated sensor resists rain and salt water and can even survive total immersion. It is also fully configurable using SenixView configuration and analysis software.

Lightning resistance has been improved with protection 75% stronger than CE EMC requirements. ToughSonic remote 14 sensors can continue to operate even after absorbing repeated 7 kilovolt transients. “We have customers deploying water level monitoring stations in some of the most lightning-prone areas of the world,” says Doug Boehm, founder and CTO of Senix. “We engineered our new remote sensors to provide an extra measure of survivability.”

In addition to surge protection, The ToughSonic remote 14 addresses other remote monitoring issues. An all-digital sensor using serial data communications with Modbus or ASCII protocols, the ToughSonic remote 14 offers direct digital communication with data collection and networking devices. It powers up in less than one second and uses up to 21% less energy – important when sensors are operated intermittently and powered by solar panels and batteries. “Water management companies are investing heavily in automation. Irrigation automation has been especially strong,” says Boehm. “Our remote monitoring customers need a rugged, energy-efficient, all-digital sensor that they can rely on. We built the ToughSonic remote 14 for them.”

Advanced remote monitoring systems that rely on ToughSonic include the Philippine Tsunami, River and Urban Flood Monitoring System and Iowa’s Flood Information System.
