DRIVING TORQUE DETERMINATION ON THE AIR FLOW TRANSDUCER SENSITIVE ELEMENT

 

Abstrakt. Article aims to solve the problem of air flow rate and quantity accurate measurement for diagnosing human respiratory.
The problems of driving torque determination on sensitive element blade of velocity type measuring flow rate transducer are considered. One of the main factors which affect on the driving torque value is the flow velocity distribution just before sensitive element. Based on this, particular attention is paid to the nature of measuring flow velocity distribution before the sensitive element and its interaction with instrument constructive elements. Further researches related to the definition of resistance moments to sensitive element rotation.


Keywords: air flow rate, meter, mathematical model, driving torque.
