Portable non-invasive clamp-on ultrasonic flow-meter for liquids
Sierra Instruments

Our Innova-Sonic® Portable Model 210i is a portable ultrasonic flow meter featuring improved digital signal processing and a user friendly tactile keyboard on the face for easy data entry and retreival. Sophisticated electronics coupled with powerful ultrasonic transducers deliver highly accurate flow measurement for liquids in full pipes. While principally designed for clean liquid applications, the instrument is tolerant of liquids with a small quantity of air bubbles or suspended solids common in most industrial applications - making it ideal for measuring nearly any liquid.
