FIELD: measurement equipment.
SUBSTANCE: portion of controlled fluid is supplied to reservoir 1 through flow control 10 and inlet nozzle 2, which is heated by vapour generation of non-dissolved water. Acoustic waves occur at breakage of the cover with vapour, which are converted by means of acoustic receiver 5 to electric signals, which are supplied through amplifier 7 and counter 8 to indicator 11. Timer 9 controls counter 8 and flow control 10. Reservoir 1 is closed with cover plate 4, inside which cone insert 6 is located.
EFFECT: simpler design and higher measurement accuracy.
