徴とする液体定量混入制御装置。 A pulse oscillation flowmeter that detects the flow rate of fluid in the main pipe, an automatic flow rate adjustment valve that controls the flow rate, and a pulse oscillation flowmeter that detects the flow rate are installed on the side of the liquid feeding device that mixes into the main pipe. , has a pulse oscillator for setting the magnification that sets the ratio between the flow rate of the main pipe and the flow rate of the mixed liquid, and has a flow meter for the main pipe, a flow meter for the mixed liquid, and the number of pulse oscillations for each for setting the multiplier. A calculation circuit is provided to perform comparison calculations, and the calculation circuit calculates the set flow rate of the mixed liquid, and calculates the driving time for opening or closing the automatic flow rate adjustment valve based on the size of the difference between the current flow rate and the set flow rate. The liquid quantitative mixing control device is characterized in that the ratio of the flow rate of the main pipe to the flow rate of the mixed liquid is adjusted to a set value.
