Patent ID: 8918293

Claim:
A flow meter for monitoring fluid flow comprising: a conduit having a fluid inlet and a fluid outlet configured to be in communication with respective sections of a pipeline; a target element positioned inside the conduit between, with respect to a first axis, the fluid inlet and the fluid outlet, the target element being mounted for resilient axial displacement with respect to the first axis under a pressure differential between the inlet and the outlet; an arm secured at an anchor point on one side of the conduit and extending radially across the conduit along a second axis that is transverse to the axis, the target element being coupled to the arm for applying a load to the arm, upon said axial displacement of the target element, so as to deflect the arm relative to the anchor point, wherein the target element is located, respective to the second axis, between the anchor point and a deflection measurement point; measurement point; a sensor arrangement configured to measure deflection of the arm at the deflection measurement point; and a processor configured to provide a signal representative of the fluid flow through the conduit in response to said measured deflection.
