This consists of a number of calibrations at various fluid viscosities which cover the range of interest. Data resulting from all the calibrations are presented as K-factor, Meter Factor or Error as a function of flowrate ( or frequency) divided by kinematic viscosity. This ratio can be written Q/ ν. 0 1 000 2 000 3 000 4 000 5 000 6 000 7 000 8” HELIFLU™ TZN 8-6290 - 629 to 6290 Bbl/h (100 to 1000 m3/ h) 108 cSt 0,62 cSt August 1987 September 1995 1,63 cSt 4 cSt 49,2 cSt 18 cSt Meter factor F (MF) Flowrates (Bbl/hr) Fluid viscosity = 0.62 to 108 cSt 8” HELIFLUTM TZN Universal curve for viscosity compensation HELIFLUtM 0.9980 1.0000 1.0020 1.0040 1.0060 1.0080 1.0100 0 10 100 1 000 10 000 100 000 Meter factor F (MF) Q/νINDEX (Bbl/hr/cSt) Fluid viscosity = 0.62 to 108 cSt The HELIFLU™ TZN Flowmeters meet International measurement Standards.
