| 摘要 |
A hot wire anemometer flow meter device is disclosed which is particularly adapted to be inserted down hole in a gas or oil well line or casing to accurately measure fluid flow through the line. The device comprises an elongate member formed of a plurality of tubing segments or modules interconnected in an end-to-end axial orientation. The segments located adjacent opposite ends of the elongate member include a plurality of arm struts, extensible radially outward to selectively anchor and axially register the device in a desired location within the line. Each of the arm struts mount one or more hot wire anemometers which yield a varying current signal in response to fluid flow across the same. A temperature gauge, pressure gauge, directional indicator, phase gauge, and battery source are additionally provided which enables the current signals obtained from the anemometers to be calibrated and integrated mathematically to yield accurate flow measurement results irrespective of laminar or turbulent flow conditions within the line.
