Water control computer is widely used in internal water use occasions such as boiled water rooms, bathhouses and apartments of campuses, enterprises and government organs. It can realize simple and convenient installation and water consumption control, realize electronic and intelligent transaction and settlement, and improve users' management efficiency and management means. It is the most important part of campus and enterprise all-in-one card. It has the advantages of small volume, low power consumption, long service life, perfect function, anti-theft water, power-off and valve closing. The flow accuracy is within 5 thousandths. It adopts copper body and high temperature resistance.
