The Armstrong International VERIS Verabar V500/V510 Flanged Flow Sensor, developed from aerospace technology, provides unsurpassed accuracy and reliability in flow measurement. With its solid one-piece construction and bullet shape, the Verabar makes flow measurement clog-free and precise, delivering stable signals even in demanding process conditions .

The V500 features flanged single support mounting, while the V510 offers flanged double support mounting for additional stability in larger line sizes or higher velocity applications. When 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. Multiple sensing ports are positioned in these high- and low-pressure zones, and an averaged differential pressure is measured, providing a more representative measurement of the true flow profile than single-point sensors.

The Verabar design uniquely locates the low-pressure ports on the sides of the sensor, forward of the fluid separation point and turbulent wake area, virtually eliminating clogging and producing an extremely stable signal. This reduces noise and improves control loop performance, with superior performance even in dirty fluids.

Verified accuracy eliminates the need for calibration tests to characterize coefficients, with empirical test data from independent laboratories published in the VERIS Verabar Flow Test Report (VED-100). Ready to install, the Verabar can be ordered with a manifold, transmitter, local indicating meter, flow computer, and/or recorder. Complete installation is possible in less than an hour. Accuracy is ±1% of flow rate, up to ±0.5% if calibrated, with ±0.10% repeatability over the entire flow range. Flanged connections are rated up to ANSI Class 600.
