Pune-based crystal engineers supplies ce approved ultrasonic digital level indicators, manufactured by lundhal, usa, a self-contained sensors with digital compatible electronic output. They offer non-contact level monitoring suited to harsh chemical environment and microprocessor controlled sensors eliminate error due to vibration and shock. The output range is 4/20 ma dc. Model u/5 uses sophisticated ultrasonic technology for reliable non-contact monitoring of liquid levels in tank, drums and containers. The enclosures are as per pvc nema 4x ip 65. Accuracy is 0.5 percent of range without temperature gradient and the transducers are designed to ignore unwanted echoes originated at the perimeters of the ultrasonic beam pattern, while the temperature compensation is done internally.
