Fluid flow sensor assembly with high turndown ratio and low pressure drop

摘要: A fluid flow sensor assembly comprised of a plumbed to convey in parallel with normally-closed, high-flow valve, displaceable an opened position response hydrodynamic force, for placement into conduit achieve precise measurement the volumetric high turndown ratio at pressure drop below which alone would impose, is disclosed. In addition, mathematic relationship output rate through assembly, throughout range,
