The utility model relates to the technical field of chemical production process control multi-parameter adjusting devices, in particular to a multi-liquid-level automatic adjusting device which comprises a liquid supply header pipe, at least two liquid storage tanks and liquid supply branch pipes matched with the liquid storage tanks in number. The tank bottom of each liquid storage tank is communicated with one end of a liquid supply branch pipe, the other end of each liquid supply branch pipe is communicated with a liquid supply main pipe, and a liquid level meter capable of monitoring the liquid level in the tank is installed outside each liquid storage tank. The liquid storage tank is reasonable and compact in structure and convenient to use, the problem of mutual influence of multipleliquid levels can be effectively solved, and the liquid levels and the outlet flow of all the liquid storage tanks are dynamically balanced through automatic adjustment of the multiple automatic adjusting valves. An operator only needs to automatically put into operation after stable production, an alarm value and a control target value are set according to production requirements, the operator only needs to carry out proper data monitoring, the labor intensity of the operator is relieved, and the labor production efficiency is improved.
