Background
At present, when liquids are mixed according to a proportion, the liquids are mixed by a method that each liquid is input according to flow control, and the flow control is most commonly carried out by adopting a mode of installing a flowmeter. When liquid flows through the flowmeter, a pulse signal is output, and the volume of the liquid can be calculated by capturing and accumulating the pulse signal. When the method is used, a flowmeter and a control valve are required to be installed on an outflow pipeline of each liquid, when the method is used, the control valve is opened firstly, the liquid flows through the flowmeter, pulse signals are output outwards, the control valve is closed when the pulses of the flowmeter are detected and accumulated to calculate the number of the specified liquid volumes, and the outflow part of the liquid is the liquid volume needing liquid mixing.
