Abstract
A sensing element is provided for use in a system for measuring fluid flow, such as, turbulent air flow. The sensing element comprises a sensor body and a first load cell arrangement connected to the sensor body. The sensor body has a three dimensional shape which is rotationally symmetric about a longitudinal axis passing through the first load cell arrangement and the sensor body. The first load cell arrangement is configured to measure the force exerted on the sensor body by fluid flow in at least an xy plane perpendicular to the longitudinal axis. A system for measuring fluid flow comprising the sensing element and a method for measuring fluid flow using the sensing element and the system are also provided.
