Fullbore Spinner


The Fullbore Spinner is a versatile and reliable fluid velocity measurement tool that incorporates a collapsible impeller that allows the spinner to be run through tubing and expand into a large diameter casing. This design provides a velocity measurement of a large cross-sectional area. The sensitivity of a Fullbore Spinner results in accurate flow measurement across the well diameter.


  • Collapsible Impeller

  • Large Cross-Sectional Velocity Measurements

  • Increased Sensitivity - More Accurate Flow Measurements


The Fullbore Spinner is designed to have collapsible arms that can collapse down to 1.375” which allows the spinner to log variable casing sizes.
