Remarks: 
The FBC type flow instrument provides a conventional ‘flat-bladed’ fullbore Flowmeter combined with a dual axis (X-Y) calliper. (See the FBF for a stand-alone flow instrument). The spring cage of the flowmeter provides sufficient centralisation force to eliminate the requirement for a lower centraliser when deployed with a typical production logging string.
