ULT 200

Product Description

ULT 200 Two-Wire Ultrasonic Level Transmitter is designed for accurate non-contact liquid level measurement using ultrasonic time-of-flight technology. It operates on a 2-wire loop-powered (4–20 mA) system, ensuring easy installation and reduced wiring requirements. With a measuring range up to 12 meters, it is ideal for applications involving slurries, corrosive liquids, and wastewater. The transmitter features automatic temperature compensation and narrow beam technology for stable and precise readings. A built-in LCD display provides clear local indication, while optional HART communication enhances configuration and diagnostics. Compact and reliable, the ULT 200 minimises maintenance and process downtime in industrial environments.
