摘要
A heat-sensitive flow rate sensor employs a measuring resistor unit which has patterning wirings formed on a heat-sensitive resistor and presenting a principal pattern which extends in parallel with the longitudinal axis of the measuring resistor unit. Temperature distribution over the heat-sensitive resistor is made uniform so that measuring error due to change in the temperature of a measured fluid is reduced, thus enabling flow rate measurement at enhanced accuracy.
