Target Insertion Flowmeter Principle of Operation

Flow is measured in terms of dynamic force acting on a target (solid disk) in the flow stream.Hermetically sealed,bonded strain gages in a bridge circuit configuration mounted outside the flow stream translate force into an electrical output.This output is proportional to flow rate squared. Wide RangeabilityEasily and inexpensively field modified by replacing targetfor extreme flow range changesVersatile MountingFixed, retractable (hot tap), and moreOptionsDurableNo frictional moving parts to wearDesigned to withstand 100% over rangeFast ResponseTypically less than 2 msec.Time Figure 1.
