  • Device for measuring flow rate of fluid in a pipeline
    Patent number: 4168725
    Abstract: The measuring portion of a pipeline comprises substantially the same pipe as that forming the mainline. A slot is longitudinally provided in the measuring portion thereof. An orifice plate is inserted into the measuring portion through the slot and is then turned so as to be arranged across the measuring portion. The slot is sealed by means of a special cap plate.
