Our range of ultrasonic level switches and sensors are designed to operate in a wide spectrum of liquids, ranging from oils to inks. These rugged transmitters are typically constructed from stainless steel and built to withstand high pressures, temperature, and vibration and operate in a broad range of liquid media.

These are designed to provide accurate and reliable level sensing for difficult to monitor fluids, where contact with media is not desirable from the extremes of sending: ultrapure to corrosive or even dirty where coating or scaling is possible. Ultrasonic level transmitters have no moving parts, are easy to install and simple to use.

XLS-1 Ultrasonic Level Sensors

Our XLS-1 Ultrasonic Level Sensors are compatible with water-based and hydrocarbon-based liquids and are perfect for applications where condensation may affect other sensing technologies. The XLS-1 single point level sensor has no moving parts to wear out over time (zero maintenance), ignores condensation and will not sense foam as a liquid. This cost-effective unit is ideal for use in generators, water tanks, radiators, printers and many other industrial applications.

UCL-510 & UCL-520 Ultrasonic Level Transmitters

Our UCL-510 & UCL-520 Ultrasonic Level Transmitters are designed to provide accurate and reliable level sensing for “difficult-to-monitor” fluids, providing non-contact level measurement for large tanks.  This non-contact design is ideal for ultrapure, corrosive or dirty media where coating and scaling is possible. Again, these units have no moving parts and are extremely easy to install, setup and use. More information can be found here on our product page.
