Claim Text:
1. An apparatus for characterising a flow through a conduit, the apparatus comprising: a body portion having a longitudinal axis extending between first and second body portion ends, wherein the cross-sectional area of the body portion varies along the longitudinal axis, and wherein, in use, the body portion is arranged to be disposed substantially longitudinally within the conduit with the first body portion end disposed upstream of the second body portion end; a first sensor disposed at or near the first body portion end; and a second sensor longitudinally spaced from the first sensor, wherein the body portion has a larger cross-sectional area at the second sensor than at the first sensor such that, in use, the second sensor experiences an accelerated flow as compared to the first sensor; wherein the first and second sensors are operable to sense a common variable, thereby enabling the effects of accelerated flow on the common variable to be characterised.
