<p>Fluid flow measurement device and method. In one embodiment, a tool comprises a rotating arm with a sensor pad to measure fluid flow into or out of the casing wall. The arm maintains the sensor pad in close proximity to the casing inner wall. The tool diameter is variable to allow the tool to traverse variable diameter casings and pass obstacles. The sensor pad comprises flow channels to direct the flow of fluid by electromagnetic sensors configured to detect conductive fluid flow.</p> |
