Test section details:
Two phase flow intruments of Horizontal pipe test section Instruments are located in the 2m pipe sections which are connected by Gray Locks to form a 10m horizontal pipe test section. A pitot tube and a correlation flow meter are used to measure the liquid and steam velocities. Five point CPT(conductivity probe with thermocouple) rakes and three-beam r-densitometers will be used to measure the liquid levels and the fluid density.
