PURPOSE: To prevent the vibration of measuring signal and to improve accuracy by supplying according to the difference between the 2nd set up weight which is bigger than that in case of a measuring signal being less than the 1st set-up weight and by controlling the supply with a specific signal in case of more than 1st set-up weight.
CONSTITUTION: The signal that the supply from a supplying unit 2 is measured at a measuring part 4 is compared by a comparative means 6 with the 1st set up weight and in case of less than 1st set-up weight the function signal of the difference from the 2nd set-up weight which is larger than the set-up weight thereof is transmitted to the unit 2 from the 1st controlling signal generating means 8. When the measuring signal is found bigger than the 1st set-up weight the prescribed signal is transmitted from the means 6 to 2nd controlling signal generating means 10 and the means 10 transmits to the unit 2 the signal that has the size less than the function signal at that time and the size is constant. The vibration of a measuring signal can be thus prevented with the continuous controlling of the flow by the signal from the means 8 and the measurement with good accuracy can be performed by the signal from the means 10.
