ABSTRACT:
A flowmeter for use in sanitary applications where the flowmeter possesses a member that intrudes into the process fluid. The flowmeter includes a round pipe and a flow obstruction element that is uniquely secured in the pipe wall section. A co-planar section having an aperture is formed in the pipe wall. The flow obstruction element which has an enlarged head at one end is inserted through the aperture into the interior of the pipe. The enlarged head has a flat outer surface and a flow contact surface that is flat in the section adjacent its perimeter. The head is positioned so that the section of its flow contact surface adjacent its flow contact surface perimeter is co-planar with the inner surface of the co-planar pipe wall section. The side surface of the head is bonded to the side surface circumscribing the aperture in the co-planar pipe wall section. The flow contact surfaces of the flow obstruction element and the inner surface of the pipe wall are of low fluid collectability thereby preventing entrapment of process fluids.
