Laminar flow is created when fluid or gas flows in stable parallel layers without any turbulent movements appearing between the layers. LFE are specifically designed to measure such flows. Their working principle is that such types of flow possess a linear relation between the pressure and the flow rate. Commonly LFE comprise a set of parallel tubes long enough to create required type of flow inside of these tubes. You will find great deals for LF elements - only on MegaDepot.
