Jeweled Bearing Continues Flowmeter

The CNPS Jeweled Bearing Continuous Flowmeter employs jewels to reduce the threshold and improve upon the sensitivity of the CFS. It is available in a number of sizes to suit particular applications and is run as the lowest tool in a string.


The tool is rugged and particular attention has been paid to the protection of the spinner unit. This Flowmeter performs in all well orientations from vertical to horizontal. This tool performs well in high velocity flows and can also be used where some sand production occurs.



The spinner is mounted between jeweled bearings and rotation detection is through zero drag Hall effect devices, giving very low threshold and optimizing low flow measurement. At high flow rates the Flowmeter is similarly reliable due to dynamic balancing and careful design of the rotor impeller. The tool outputs flow direction information.
