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.
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%.
4.4 The tapping body is machined from stainless steel forgings to ensure overall strength and to
minimize possible leakage points.

6 Unpacking and Inspection
6.1 Precautions for Unpacking Inspection
Check the quantity and material of each part against the packing list.
6.2 heck Content
Check whether the appearance of the instrument is defective or damaged.
7 Installation
7.1 Flow element is butt welded with the on-site pipeline to ensure the welding quality and
suppress no leakage.
7.2 Installation Technical Requirements
7.2.1 When installing the integral orifice flow meter, pay attention that the direction of the inlet and
outlet is consistent with the direction of the "+" sign on the integral orifice plate.
