FLM-B Production Logging Tool

FLM-B

Continuous Flowmeter

The FLM-B Continuous Flowmeter is used to make fluid flow-rate measurements in producing wells.  It contains a unique 24 pulse/revolution sensor section that operates with the SPN-B rotating magnet impeller unit.  The electronics section digitizes the sensor count-rate and produces a 12-bit binary word including a direction bit.  The high number of pulses per revolution together with the low threshold of the SPN-B and the fast 16 times/second sampling allow unprecedented resolution of complex flow regimes.

The SPN-B Spinner is equally sensitive to fluid flow in both axial directions, with a rotation rate linearly proportional to flow speed.  A new shrouded design eliminates sensitivity to transverse flow, or Coriolis effect, which can lead to serious errors in inclined or horizontal wells or where the flow from perforations may enter the casing at significant rates.
