a first temperature sensor for measuring the temperature outside the boundary layer, which is located downstream of the heater and is disposed between the liner and the insulating film in contact with the outer surface of the insulating film; and a second temperature sensor located upstream of the temperature sensor and on the inner circumferential side of the conduit for measuring the temperature inside the boundary layer, and supplying temperature signals to the heater from the first and second temperature sensors. A boundary layer flowmeter consists of a measuring section that measures the mass flow rate by changing the current, voltage, or power.
