Tube wall pressure tower flowmeter

Tower shaped flowmeter for wall pressure measurementThe present utility model relates to a tower shaped flowmeter for measuring pressure on a pipe wall, comprising a measuring pipe. The measuring pipe is equipped with a throttle element supported on the inner wall of the measuring pipe through an L pipe. Positive and negative pressure ports are respectively opened on the measuring pipe wall in front and behind the throttle element. This method of opening the negative pressure port on the pipe wall is called pipe wall pressure tapping.
