UD2000 - Intelligent Ultrasonic Level Meter

UD2000 operates on the basic principle of using sound waves to determine liquid/solid/slurries level. Ultrasonic pulse signals are transmitted and reflected from the liquid surface. The transmitter 'listens' for reflected signals (echoes) and measures the time-delay between transmitting and receiving. The distance to the sensed material surface is automatically calculated using the computed time-delay. Applications: water distribution system, food and pharmaceutical industry, power plant, barn, steel mill and fiber industries.
