The cage arms are formed from six tungsten carbide coated bow springs, with additional coil springs built into the folding mechanism which are capable of supporting the weight of the tool in a horizontal well into and pulling out of hole.
OPERATING PRINCIPLE
The Flowmeter may be closed down to tool diameter while running or pulling out of hole, and opens automatically when it leaves the tubing to enter the casing. Should a restriction be encountered during logging, the flowmeter will close and fold the spinner until the restriction is passed, thus avoiding damage to the blades. The spinner runs on precision bearings. Rotation is sensed by zero drag Hall effect detectors allowing the measurement of very low flow rates. The normal output is 10 pulses per revolution with directional information.
