A flow meter (100) for measuring a mass flow rate of a fluid flowing through a conduit (112) includes a target (132), having an area, capable of being inserted into the conduit, a rod (134) having a first end (136) and an opposite second end (138), the first end affixed to the target, and a connecting member (160) having a first portion (162), a spaced-apart second portion (164), and a flexible portion disposed (166) between the first portion and the second portion. The first portion is capable of being secured to the conduit and the second portion is affixed to the second end of the rod. The flexible portion has a flexibility so that movement of the target results in a translated movement of the second portion via the rod. Thus, movement of the second portion is proportional to the movement of the target. A sensor (140) senses displacement of the second portion along a first axis (C'-C") that is substantially parallel to a direction (A) of fluid flow within the conduit and also senses movement of the second portion along a second axis that is transverse to the first axis. A device (170), responsive to the sensor, determines a flow rate of a fluid flowing through the conduit, based on the displacement sensed by the sensor along the first axis and the movement sensed by the sensor along the second axis.
