Model:
Use:Impellers can detect differential flow rates as low as 1.0m/min.
Impeller Flowmeter Probe
Impellers can detect differential flow rates as low as 1.0m/min.
Logging at a range of speeds allows detection of flow of any rate (although for high precision in low flow rates use of the Heat-Pulse Flowmeter is advised).
Principle of Measurement:
The probes are equipped with lightweight helical impellers mounted on double sapphire bearings. The impellers contain magnets which actuate Hall-effect switches within the probe to detect impeller rotation. Separate log channels record the time of rotation according to fast and slow timebases for improved resolution at high and low flow rates. Uphole and downhole rotations are distinguished within the probe.
