An instrumental error compensating method has super precision measurement function, even in a condition having only micro temperature changes, by utilizing a computer which compensates for flow rate errors instantaneously and sends signals for indicating corrected values. Flowmeter (1) of the type having elliptical gears or roots type rotor has temperature sensor (5) mounted thereon and a rotation sensor (6) for indicating temperature and rotational speed of rotor. The signals from the sensors as fed to microcomputer (100). The errors can be caused by wear temperature changes, and viscosity chanter, for based on flow rate and temperature of the fluid detected by the sensors.
