Continuous Jeweled Bearing Flowmeter (IFJM11)

Applications
Features
  • · Production profiling
    · Injection profiling
    · Logging in sand screens /slotted liners
    · Particularly good for use In high velocity

  • The Jeweled Bearing Flowmeter (mechanical section) employs jewels for the
    support of the spinner pivot to reduce threshold displacement and improve
    sensitivity. The tool is very rugged as the housing provides the spinner with
    good protection. The flowmeter is applicable to all deviations, from vertical to
    horizontal.


    The HTF02 is connected to measure the downhole flow rate. The mechanical
    section is composed of upper sub, outer cage, spinner and central spindle.
    Both ends of the central spindle are supported by a jeweled bearing
    respectively. Moving fluids flowing through the spinner may rotate the spinner,
    which then rotates the magnetic steel on the central spindle to trigger Hall
    device assembly in the HTF02 to generate 10 pulsed signals per revolution.
    The signals are processed in circuits first and then transmitted to the surface
    system.
