Abstract: PURPOSE:To quickly and easily measure the flow of arbitrary fluid without conducting calibration on each part of a device by measuring the heat capacity of the flow on the basis of an acumulated heat capacity and temperature change for the fluid within a tube in a stop state. CONSTITUTION:With a heater 2 heated, a measurement-intended fluid Sa within a tube 1 is heated, and the temperature after a specified time is detected by the use of a downstream side temperature detection sensor 7.
