Document Type and Number:
Japanese Patent JP3385308
Kind Code:
B2
Abstract:
Disclosed is a thermal flow meter which is relatively inexpensive and operates with high accuracy and reliability, and a fuel controller using the thermal flow meter adapted for internal combustion engines. The thermal flow meter comprises a sensor unit for detecting a flow rate signal, a reference power supply for generating a reference signal, and a signal switch for selectively outputting the flow rate signal from the sensor unit and the reference signal from the reference power supply. The flow rate signal and the reference signal are alternately output from the same output terminal.
