METHOD FOR DEFINING TRUE LOCAL VOLUME VAPOUR CONTENT Russian patent published in 2008 - IPC G01N25/64 

FIELD: measuring equipment.

SUBSTANCE: method involves function t_s.e.=f(τ) as relation obtained by interaction of sensitive probe element with two-phase flow, heated soldered thermocouple junction is used as sensitive probe element, interaction time Δτ_i of sensitive probe element and elementary vapour inclusion is defined on the basis of function Δτ_i=τ_ei-τ_bi, where τ_ei, τ_bi are respectively the time of interaction end and beginning between sensitive probe element and elementary vapour inclusion, τ_ei, τ_bi are defined as points of function t_s.e.=f(τ), where value dt_s.e./dτ is variable, t_s.e. is temperature of heated sensitive thermocouple element reached during interaction of heated sensitive thermocouple element with two-phase flow.

EFFECT: improved reliability and precision of definition.
