Abstract: A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a microcontroller accommodated inside the meter body. The microcontroller is electrically connected with the speed transducer, the temperature transducer and the temperature compensator. The temperature transducer only functions to detect the temperature of the surrounding gas. The temperature compensator only functions to compensate the speed transducer for the temperature drop thereof. Each of them functions independently. Once the temperature of the speed transducer lowers, the temperature compensator directly compensates for the temperature drop, whereby the statistic error value is effectively decreased. A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a ...more ...less

Abstract: A method and system for evaluating both fluid type and fluid flow downhole by applying thermal energy in a flow of the fluid, and monitoring downstream temperature over time to generate a temperature profile. The type of fluid being evaluated can be determined by comparing the measured temperature profile to profiles over time of known fluids because these profiles depend upon these fluids' thermal diffusivities and flow rates. Further, stratified flow in a deviated wellbore can be analyzed by conducting the fluid evaluation at different radial locations in the flow stream so that the presence of water, liquid hydrocarbons, and gas can be identified. The system can include a pivoting arm that selectively spans the wellbore diameter, and which includes multiple thermal sources, each with corresponding thermal sensor, that are spaced along the arm. A frame can be provided for each of the sources and sensors, which is automatically self-oriented along the direction of fluid flow like a weather vane.
