........................................................................................................................................... 5
4.1 Transmitter and flow element integrated installation, saving installation and maintenance
work. ........................................................................................................................................................................ 5
4.2 Integral orifice plate has an internally polished straight pipe section with 20 times the pipe
diameter upstream and 10 times the pipe diameter downstream, which achieves a good
rectification effect and reduces uncertainty. .............................................................................................. 6
4.3 High precision, after the actual flow calibration of integral orifice plate flow meter, the
basic error of the flow coefficient can be up to ± 0.5%. ......................................................................... 6
4.4 The tapping body is machined from stainless steel forgings to ensure overall strength and
to minimize possible leakage points. ........................................................................................................... 6
