The utility model relates to the field of automatic liquid metering. The utility model relates to a device, in particular to an automatic water yield counting device for coalbed methane drainage. Wherein the first water tank and the second water tank are vertically connected through a water tank connecting rod and provided with water inlets and water outlets respectively, the gravity center of thefirst water tank and the gravity center of the second water tank are located on different sides of the water tank connecting rod, and a rotating shaft is installed at the midpoint of the water tank connecting rod through a bearing; the first water tank and the second water tank resist magnet attraction force along with self-gravity changes and rotate around the rotating shaft along the vertical plane. The two water tanks in the device are eccentrically arranged relative to the water tank connecting rod; the water tank is connected with a magnet group with attraction through a magnet rod; thegravity of the water tank
