INTRODUCTION
The Sono-Trak™ Doppler ultrasonic flow meter provides an accurate and easy-to-use
measuring system for high-solid fluid flow through pipes 1/2 inch to 300 inches
(outside diameter). The Doppler flow meter is well suited for flow measurement
applications such as sludges, slurries, aerated liquids, sewage, dredges, pulp, plastics,
and activated sludges. The Doppler flow meter features clamp-on transducers and a
rugged NEMA 4X enclosure, and is a long-term, maintenance-free solution for your
high-solid flow measurement requirements.
