A positioning mechanism 3 is installed on one side of the equipment tray 1. The positioning mechanism 3 positions the bottom of the electronically controlled fuel injector and adjusts the positioning range according to the size of the electronically controlled fuel injector to meet the flow measurement requirements of different sized electronically controlled fuel injectors. A flow measuring mechanism 10 is installed directly above the component tray 5. The flow measuring mechanism 10 accurately measures the output of the electronically controlled fuel injector and then performs sampling inspection on the electronically controlled fuel injector.
