Static head can be measured directly, with pressure gauge method is as follows: as shown, one end of the pressure gauge is connected with Kiln Road, pipe sections parallel to the flow direction, the other end is communicated with atmosphere pressure gauge. If the pressure is greater than the pressure outside the kiln kiln, liquid column manometer liquid column is connected with the kiln branch down, another branch pipe is rising, at this time, the vertical height of two end liquid column word, that a static head size.
