摘要
A mass flow rate sensor (8,18,102,202) for providing an output signal (Vout) related to mass flow rate ( @) past the sensor (8,18,102,202) comprising first means (19,102,202) for generating a first mass flow rate-related signal (Vb), the first signal (Vb) containing temperature-related errors (e.g., T1-Ta, T1-Ts (Ta) ) and mass flow rate-related errors (MAS error), second means (R2) for generating a second signal (R2(Ta) ) providing temperature error correction (TCOMP), third means (R1,R4) for generating a third signal (Vc) providing mass flow rate ( @) error (MAS error) correction, and means (19;30;32;34;36;38;40;B+; in Fig. 18: 102;104;106;108;110;112; and in Fig. 22: 202;204; 206;208) for operatively coupling the first (19,102,202), second (R2) and third (R1,R4) means together to provide the output signal (Vout).
