What Is Caged Full-bore Flowmeter Tool?
Netssu’s Caged Full-bore Flowmeter (CFB) accurately measures downhole flow rates with coverage over a large cross section of the casing. Run at the bottom of the production-logging tool string, the CFB centers the spinner and supports the tool weight in deviated wells.
Using a large-diameter impeller, it has the ability to detect very low flow rates, making it a valuable tool for operators and Logging engineers.
The tool has a 6-arm, spring-loaded cage that centers the spinner in the middle of the flow and supports tool weight in deviated Wells.
A large diameter impeller measures flow rates with coverage over a large cross section of the casing. The spinner runs on precision bearings, and ts rotation is sensed by zero-drag Hall- effect detectors, the signal from which is converted into a flow- rate measurement.
The low mechanical threshold of the tool enables it to be used in low flow rates, and normal output is 10pulses per revolution with directional indication.
