The large-mouth water meter is composed of three parts: A signaling water meter, an automatic control valve, and an intelligent controller. In addition to measuring the water consumption of group users, it can also use IC cards to purchase water, and automatically alarm and stop water supply according to the purchase amount and the actual consumption of the user. The maximum allowable error of the water meter: from the low area including the minimum flow qmin to excluding the decomposition flow qt ±5%; including the boundary flow qt to the high area including the overload flow qs ±2%.
