The LONN-UL25 ultrasonic level meter provides continuous, non-contact liquid level measurement for water, oil, and chemical storage tanks. Using high-frequency pulse acoustic technology, it measures levels from 0 to 25 meters with ±0.25% accuracy. The integrated design combines transmitter, display, and RS485 communication in an IP65/IP68-rated housing, delivering 4–20mA analog output plus Modbus RTU digital interface. Ideal for industrial water treatment, petroleum storage, and chemical processing applications.
