Further, the bottom of the measuring module is connected with a supporting frame for fixing the measuring module and preventing the measuring module from toppling over, and a water outlet is formed in the bottom of the measuring module. .

The utility model discloses utilize two tipping bucket principles to calculate the weight of accepting the stem flow, respond to the steel ball and roll to tipping bucket one side down when the tipping bucket water is full of the upset, so reciprocal roll. When the steel ball is sensed to roll to a certain side, the counting sensor below the tipping bucket acquires the existence of the steel ball to generate a counting signal. And finally, signals generated by the two counting sensors are recorded by a counter, and the automatic determination operation of the stem flow of the trunk is completed.
