diameter in length and at downstream no less than 5 times of nominal drift diameter in

length. The internal wall of pipe sections shall be smooth and clean, free of defects

such as indent, fouling and peeling. The pipe axis of the sensor shall be aligned with

that of the neighboring pipe and the washers used for connection and sealing may not
