- Transient Time Flowmeters (TTF) have been given much interest in various water reactor safety programs as a method of determining a two-phase flow velocity. The determination of velocity by measuring the time interval tau for the passage of a flow disturbance between two points seems very logical. However, the major problem is how to experimentally determine this time interval, then how to interpret the velocity once it has been calculated. At ORNL, two Ramapo Inc. drag flowmeters have been tested in vertical two-phase air-water flow with good results. Three different configurations have been studied: in the first a drag body was placed 15.2 cm (6 in.) downstream of the other, in the second the separation was 29.2 cm (11.5 in.), and in the third the separation was 62.2 cm (24.5 in.).
