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. Pressure is monitored upstream and downstream of the orifice plate to determine the pressure difference for calculation of the flow rate of the fluid in the pipeline.
