Caged Fullbore Flowmeter (3 arm CFBM)

The tool has a three arm, spring-loaded cage that centres the spinner in the middle of the flow and supports tool weight in deviated wells. The spinner runs on precision bearings, its rotation is sensed by zero drag Hall effect detectors allowing the measurement of very low flow rates. Normal output is 10 pulses per revolution with directional indication. The spinner and cage assembly collapse down to tool diameter, when running through tubing restrictions to prevent damaging the blades.

Description

The Sondex Caged Full Bore Flowmeter is run at the bottom of the Production Logging tool string. A large diameter impeller accurately measures downhole flow rates with coverage over a large cross section of the casing.

Features

• Full bore injection and production flow profiling.

• Measurement of low flow rates.

• Leak detection and cross-flow.

• Interchangeable mechanical sections to match casing size from 4 1/2 - 9 5/8in.

• Combinable with other UltraWire^TM PL tools.

• Connects to either a Flowmeter Electronics (CFBE) or a Capacitance/Temperature/Flow Tool (CTF).

• Modification kit available for connection to 1 3/8in CTF.
