All install independent water intaking valve on the water inlet pipe of every aqueous ammonia batch meter, and inside all installs independent electric conductance table and is used for measuring the electric conductance value that corresponds the aqueous ammonia batch meter inside. The ammonia water input port of any ammonia water metering tank is provided with a concentrated ammonia water delivery valve, and is connected with a concentrated ammonia water output pipeline in a parallel connection mode. Two ammonia water delivery pumps are arranged on the concentrated ammonia water output pipeline in parallel, so that the system can not work when a single ammonia water delivery pump fails, and the reliability of the system is improved.
