EMCO's [ST30] Sono-Trak™ Transit Time ultrasonic flow meter combines advanced non-invasive flow measurement technology with a versatile transmitter design to provide an accurate, maintenance-free, easy-to-install, and easy-to-use measuring system. The Sono-Trak™ Transit Time flow meter, using only one set of transducers, measures liquids for pipe sizes from 2 to 100". Reliable and Rugged High accuracy: ±0.5% of rate (factory tested); ±2.0% of rate (typical field installation); ±0.1% of rate repeatability Time domain expansion technology improves signal processing and dramatically increases resolution With no moving parts to wear over time, flow meter maintenance is non-existent Rugged, NEMA 6-rated transducers are fully submersible No pressure drop FM and CSA approvals (pending) Fast & Easy Installation Typical installations take less than 30 minutes with the non-invasive, clamp-on design using all stainless steel quick clamps No worries of flange requirements, pressure ratings, process liquid interaction issues, pipe vibrations, or upstream transitions Heavy-duty, urethane-coated cables are pre-terminated to facilitate a speedy installation Easy-to-read, blue backlit display allows for quick flowmeter set-up, featuring EMCO's patented menu-driven EZ-Logic™ user interface
