Title: Water flow volume display device for watering nozzle

Abstract: A watering nozzle includes a water volume detection unit received in the barrel of the watering nozzle and the water volume detection unit has two stationary members and a rotatable member which is rotatably connected between the two stationary members. The rotatable member has a magnet connected thereto which is rotated with the rotatable member when water passes through the rotatable member. A display unit is connected to the barrel and has a circuit board and a display member which is electrically connected to the circuit board. The times of revolution are detected by a magnetic spring switch on the circuit board and transferred into digits on the display member to show the volume of water that flows through the rotatable member and the nozzle unit connected to the barrel.
