Veris”s Accelabar flowmeter combines two differential-pressure technologies to produce high accuracy with no straight-run requirements over extended operating ranges. The meter combines unique nozzle design with Veris”s Verabar averaging pitot sensor. Straight-run “settling distance” accelerates, linearizes, and stabilizes the velocity profile sensed by the pitot sensor. The Verabar nozzle design produces and substantially increases DP output, resulting in operating ranges tested to 65-to-one. Independent testing verifies constant flow coefficient over the entire flow range, producing accuracy of +/- 0.5 percent.
