1st, the measuring state of precipitation.During precipitation, the rain container of diameter 200mm is responsible for for precipitation converging conical outlet, holds rain
Electrical ball valve below device is in normally open, and precipitation directly can inject inner funnel, reenter rainfall measurement cylinder by ball valve.Drop
Water is entered after rainfall measurement cylinder, causes water level to raise, and the float part of magnetostrictive liquid level sensor also rises, and produces displacement letter
Number it is transferred to monitoring and control equipment.
Rainfall gauge arranges upper water level value and lower water level value in rain gage bucket by central control unit.When water level rises, float
When subdivision floats up to water level value on rain gage bucket, the electrical ball valve that water level monitoring equipment starts and closes below rain container is prevented
Rainwater continues to inject, and subsequent start-up immersible pump draws water, by drainpipe draining, under the water level that can cause rainfall measurement cylinder that draws water
Drop, float part also declines simultaneously, and when water level is down to water level value under rain gage bucket, control device is automatically stopped and draws water.If static
