Supmea WSU200 and SUP-ULS-B Ultrasonic Level Meters
Product Overview
The Supmea WSU200 and SUP-ULS-B Ultrasonic Level Meters are advanced, non-contact solutions for continuous level measurement in tanks, silos, and open channels. Utilizing ultrasonic pulse-echo technology, these meters emit sound waves to detect level changes with high precision, making them ideal for liquids, slurries, and solids. The WSU200 is a wall-mounted transmitter with a 15m range, while the SUP-ULS-B offers an integrated design for up to 20m detection. With IP67 protection and versatile outputs, they ensure reliable performance in harsh environments, supporting industries like water treatment, chemical processing, and mining with minimal maintenance and easy installation.

Frequently Asked Questions
How do these ultrasonic meters work?
They emit ultrasonic pulses that reflect off the surface, calculating level based on echo time.
What is the blind zone, and how does it affect measurement?
The 0.2m blind zone is the distance near the sensor where measurement is unreliable; suitable for most tank heights.
Are they suitable for solids?
Yes, the SUP-ULS-B model handles solids and powders in silos.
What outputs facilitate integration?
4-20 mA, RS485 (Modbus), and relay alarms connect to PLCs and DCS systems.
Can they operate in humid or dusty environments?
Yes, IP67 protection ensures reliability in harsh conditions.
