What Is In Line Spinner Flow meter?
Netssu’s In-Line Spinner Flow meter (ILS) is a compact Flow- meter that can be run in combination with other production- logging tools.
With its compact design, the ILS is an easy way to measure fluid velocity in well environments too small for full-bore spinners. It is also an ideal backup for other spinners that might be damaged due to the wellbore environment.
The ILS spinner can rotate with very little friction, which makes it an ideal candidate for low-flow wellbores. Additionally, as part of the One-Line™ family of products, the ILS works in tandem with any other One-Line™ tool the operator chooses to employ.
The ILS allows for production profiling in tubing and casing within one logging run, and is less susceptible to the effects of jetting (high-velocity fluid entry from perforations) than a full- bore spinner.
The ILS has a shroud that protects the spinner blade as the tool moves through well restrictions. A combination of the ILS and the Caged Full-Bore Spinner tools provides a continuous optimized flow profile.
Precision roller bearings allow the spinner to rotate with minimal friction. As fluid moves past the spinner, rotation is detected by zero-drag Hall-effect sensors.
The spinner blade is optimized to have a very low mechanical threshold, and thus is ideal for low flow-rate wells. The signal from the Hall-effect sensors is converted into a spinner-rate measurement with direction indication (up or down flow).
