The example is the basic design of the water supply of the multi-storey building. The tap-water is

automatically supplied to the underground pool, and the water in the underground pool can be

transported to the water tower on the top of the building through the pump. The water is distributed

to every story in the building by means of gravity, and the action of the pump is controlled by the

level switch of the underground pool and that that of the water tower. In order to monitor the water

supply, the level meter is installed in the underground pool. The water storage capacity of the

underground pool is monitored at all times.
