In a wide variety of settings, the setting liquid amount is critical to production efficiency. Needed both to measure and then control this characteristic, the ultrasonic level controller was born. By emitting ultrasonic waves it bounces off the surface of a liquid and returns to sensor, from there measured times vary (depending on distance). Because no part of the instrument touches the product, continuing operation reducing maintenance and avoiding contamination a product integrated with non-invasive technology must nonetheless compete just as well as the rest. This is achievable thanks to in depth signal processing, automatic temperature compensation and robust design that can withstand the harshest of industrial environments. It features exceptional precision and reliability in level measurement control and is suitable for water/oil treatment, chemical processing as well as gas storage. Applications range over such diverse gases as nitrogen, oxygen & argon.
