Description

The QL40-SFM Spinner Flowmeter probe measures impeller rotation caused by groundwater flow in the borehole. It uses a magnetically coupled pick-up which drives a low friction, high resolution encoder located inside the lower pressure housing. The encoder produces 256 pulses per shaft rotation. It has quadrature sensing electronics that instantaneously detect flow direction changes.

The QL40-SFM flowmeter tool is stackable within the Quick Link (QL) product line or it can be run as a standalone tool.

Applications

  • Pumping flow profiles in screened or perforated cased holes
  • Identification of hydrostratigraphic units
  • Determine quantitative interval specific flow rates
  • Confirmation of predicted transmissive zones in open hole
