Abstract
A target meter comprises a plug 12 which is movable relatively to an orifice plate 8 against a spring 20. The spring transfers the force on the plug 12 to an abutment 26, 42. The force applied to the support 26, 42 is detected by strain gauges 30, 44 and the signals from the strain gauges are processed to provide a measure of the flow rate or of the pressure drop across the orifice plate 8.
