Vortex flowmeter with external sensor
A vortex flowmeter for installation in a pipeline requiring periodic flow rate testing is described. The flowmeter includes a flow tube forming a passage for the fluid to be metered and an obstacle assembly mounted in the tube and capable of generating fluidic osscillations causing a deflectable section of the assembly to vibrate at a corresponding frequency proportional to flow rate. The vibrations of the deflectable section are transmitted to a coupling point outside of the flow tube, whereby flow rate may be determined by an external sensor engaging the coupling point to produce a signal which is fed to a portable test set serving to convert the signal into a flow-rate reading.
