Several different methods of calculating mass flow using drag disc/turbine transducer (DTT) data, obtained at the Transient Flow Calibration Facility, are presented. Data obtained from the DTT rake were used in conjunction with density profiles obtained from a six-beam gamma densitometer to calculate a mass flow. A load cell based system was used to obtain a reference mass flow. The drag disc/densitometer combination was found to predict the mass flow with more accuracy than either the turbine/densitometer or drag disc/turbine combinations, when comparing the results with the reference mass flow. The drag disc/densitometer combination was within +-6.3% of the reference integrated mass flow for all tests. Results of the comparisons and the accuracies stated therein are expected to hold for the DTT rake assemblies installed at the Loss-of-Fluid-Test (LOFT) Facility.
