Abstract

Inventia se refera la un aparat pentru masurarea fluxului volumetric folosind procedeul de desprindere a turbioanelor, utilizat, în special, în domeniul tehnicii respiratiei si narcozei. Aparatul, conform inventiei, dupa procedeul de desprindere a turbioanelor, are intrarea sa legata pe de-o parte, prin intermediul unui filtru trece-jos, unui amplificator si unui prim circuit-poarta legate în serie, la o intrare a unui comutator, iar pe de alta parte legata, prin intermediul unui al doilea circuit-poarta, la a doua intrare a comutatorului, comutatorul fiind conectat la un transformator de frecventa-tensiune cu un circuit-poarta montat în continuare, care este, la rândul sau, legat în comutator.
