摘要（英）：

The utility model relates to a cereal seepage flow coefficient test field discloses a cereal seepage flow coefficient testing arrangement, and it includes control box, cereal container, mass flow meter, little differential gauge, air duct, air pump and gets the pressure hose, be equipped with the filter screen in the cereal container, enclose into the voltage -sharing cavity between the bottom of filter screen and cereal container, be used for placing cereal on the filter screen, the air pump passes through air duct and voltage -sharing cavity intercommunication, and mass flow meter connects in air duct, mass flow meter passes through the connecting wire and is connected with control box, hose and voltage -sharing cavity intercommunication are pressed through getting to the one end of little differential gauge, and the other end of little differential gauge presses the hose and the top of cereal container to feed through through getting, little differential gauge is connected to control box through the connecting wire, it is poor with air pressure that control box is used for gathering air mass flow to it calculates to carry out the seepage flow coefficient. The utility model discloses can realize that automatic on -line acquires cereal seepage flow coefficient.
