Paper Abstract

A flowmeter with a variable-area orifice has been investigated to measure low gas flows with low pressure drops in a pipe of internal diameter 150mm. A 'petal' construction is used with alternate fixed and flexible segments in a symmetrical arrangement about the axis of the pipe. A non-contacting optical fibre sensor is employed to monitor the deflection of a single petal as flow varies. Flows have been measured in the range 0.35 to 1.5ms-1 with a maximum pressure drop of 375Pa.
