Description
The Capacitance Flow Electronics & Temperature Tool (CFT104) offers a reduced length multiple sensor solution. All standard Fixed Cage Spinners and our Full Bore Spinner are compatible with the CFT.
The capacitance sensor provides an indication of the fluid type surrounding the sensor by measuring the dielectric constant of the fluid between the sensor and tool body. Used in combination with other sensors it provides qualitative fluid identification data. A dedicated hall effect array provides 10 pulses per revolution flowmeter output and a fast response PRT measures well bore temperature.
