Remote Liquid Level Sensors

ToughSonic REMOTE liquid level sensors are designed for accuracy and durability in remote monitoring applications.  They include the same 316 stainless steel housings, full epoxy potting, UV resistant cables and rugged piezoelectric transducers as our ToughSonic sensors, but with enhanced lightning resistance and reduced energy consumption. These digital ultrasonic sensors are designed for years of trouble free operation in harsh outdoor environments.

ToughSonic REMOTE sensors were developed specifically for remote monitoring systems. Whether measuring channel level in an irrigation management system, river level in a flood warning system or tank level on a remote drilling site, remote sensors require an extra measure of efficiency and reliability. ToughSonic REMOTE sensors are IP68 and NEMA 6X rated and include Senix Lightning Guard protection against repeated 7Kv electrical transients They are fully configurable with SenixVIEW sensor configuration and analysis software. That’s why they are installed in some of the largest and most sophisticated remote liquid level monitoring systems in the world.

Customization Options Available:

  • Pre-loaded parameter configuration and calibration for volume applications.
  • Alternative cables, lengths and connectors.

What our customers say...

U.S. NOAA logo

We use the sensors to measure water during the summer, ice and snow during the winter.  They have been working very well.  The waterproof SS case you put it in is a major plus during extreme weather events.  Love the PC feature.
