Abstract
Invenţia se referă la domeniul construcţiei de aparate, în special la măsurarea parametrilor mediilor fluide, de exemplu, ai gazului, lichidului, inclusiv lichidului termic.Termotraductorul (1) este montat într-un izolator (2). Înfăşurarea termotraductorului este conexată cu o sursă de alimentare electrică (4), deviatorul de căldură (3) este montat paralel cu termotraductorul (1), astfel încât fluxul termic, curgând de la termotraductor (1) la deviatorul de căldură (3), este perpendicular pe direcţia fluxului mediului fluid şi este modulat de către acesta. Schema de măsurat (5) măsoară energia electrică consumată, obţinând astfel informaţie despre temperatură până la şi după alimentarea cu energie electrică a termotraductorului (1). Se calculează diferenţa temperaturilor menţionate, după valoarea căreia se determină viteza mediului fluid.Rezultatul tehnic constă în modulaţia fluxului termic care permite măsurarea vitezei diverselor tipuri de lichide.
