構成されている流速流量検出装置。It consists of a thermistor that detects the occurrence of a Karman vortex by changing the amount of heat dissipated by the Karman vortex in the fluid being measured, and a circuit that passes a heating current through the thermistor. When the signal is generated at a low frequency, a constant current is mainly passed through the thermistor.
A flow rate detection device configured to mainly flow a current to maintain a constant temperature through a thermistor when a Karman vortex is generated at a relatively high frequency.
