The invention relates to a fully automatic evaporation overflow measuring device and belongs to the meteorology and water conservancy technology field. The fully automatic evaporation overflow measuring device comprises an evaporating dish, a water filling barrel, and a measuring barrel connecting the evaporating dish through a pipeline. The measuring barrel has two pairs of water level control switches, wherein an open overflow switch and a closed overflow switch control a drain solenoid valve, and an open water filling switch and a closed water filling switch control a water filling solenoidvalve. A magnetostrictive water level is placed in the measuring barrel to measure a real-time water level in the evaporating dish, and an electromagnetic flowmeter is connected to a right side pipeline of the measuring barrel so as to measure water filling and an overflow flow. A right side of the electromagnetic flowmeter is divided into a water filling pipe and an overflow pipe which are provided with a water filling
