The Armstrong International VERIS Verabar V550 Flanged Spring Lock Flow Sensor, developed from aerospace technology, provides unsurpassed accuracy and reliability. With its solid one-piece construction and bullet shape, the Verabar makes flow measurement clog-free and precise.
When a fluid impacts the sensor, it creates a high-pressure zone in front of the sensor. As the fluid accelerates around the sensor, a low-pressure zone is created to the sides and rear of the sensor. Multiple sensing ports are positioned in these high- and low-pressure zones, and an averaged differential pressure is measured.
Clogging can occur in low-pressure ports located in or near the partial vacuum at the rear of the sensor. The Verabar design locates the low-pressure ports on the sides of the sensor, forward of the fluid separation point and turbulent wake area. This virtually eliminates clogging and produces an extremely stable signal.
Verified accuracy eliminates the need for calibration tests to characterize the coefficients. Empirical test data from independent laboratories is published in the VERIS Verabar Flow Test Report (VED-100).
Ready to install, the Verabar can be ordered with a manifold, transmitter, or local indicating meter, flow computer and/or recorder. Complete Installation is possible in less than an hour.
