The Velbar flowmeter is suitable for high-precision flow measurement of gases, liquids, and vapors. Weiliba is a differential pressure and rate averaging flow sensor that measures flow by measuring the differential pressure generated by the sensor in the fluid. The power bar reflects the true flow velocity of the fluid, with an accuracy of ± 1.0% and a repeatability of ± 0.1%. The outstanding advantage of Weiliba is that it outputs a very stable and pulsation free differential pressure signal
