The Weiliba features a bullet-shaped cross-section design, which reflects the advanced achievements of average velocity tube flowmeters. Weiliba can accurately reflect the flow rate of gases, vapors, and liquids within enclosed pipelines (either volumetric flow rate or mass flow rate), generating a very stable and pulse-free signal. Thanks to over a century of accumulated knowledge and experience, the Wilo flowmeter continues to deliver excellent performance even in conditions of high corrosion, ultra-high pressure, and insufficient straight pipe sections. http://yunrun.com.cn/upload/201912/28/201912281458569055.png Fluid flowing over the upstream surface of the Viscosity Probe. http://yunrun.com.cn/upload/201912/28/201912281442432397.png Fluid flowing around the sides and back of the Viscosity Probe. Viscosity Probe: yunrun.com.cn/product/2853.html When fluid flows over the Viscosity Probe, a high-pressure area is formed on its upstream surface. As the fluid accelerates along the probe, low-pressure zones form on its sides and at its back. Pairs of pressure taps located on the upstream face of the probe and on its sides can detect and output an average differential pressure; based on Bernoulli’s principle, the true average flow velocity within the pipe can be determined. http://yunrun.com.cn/upload/201912/28/201912281445336746.png http://yunrun.com.cn/upload/201912/28/201912281447594910.png Schematic diagram of the working principle of Wiliba; Schematic diagram of the high-pressure and low-pressure areas in Wiliba; Advantages and features of Wiliba: 1.

How to verify accuracy better than 1%?
Thank you for sharing; it’s concise, clear, and vivid! ! !
Insertion flow meters have high requirements regarding the flow state of the fluid; if the flow regime of the medium can reach a steady-state flow (fully developed flow), its measurement accuracy can be ensured, otherwise the accuracy will not be high.
It’s my first time learning about this, and my question is: has this kind of thing been promoted widely? Has anyone used one that is more accurate than a mass flow meter?
