| Greater numbers of users are looking towards non-contact, reflective methods for level measurement, both in manufacturing processes and in storage and inventory management.
Ultrasonic technology has established itself as the first non-contact choice in many liquids and solids level measurement applications, but the performance of ultrasonic sensors is sometimes limited by difficult process environments or complex vessel geometry. Pressure or temperature changes, vapour, steam or dust presence, for example, are all factors which at best degrade ultrasonic sensors performance and, at worse, prevent their use completely. |
