8 Precautions
8.1 The flange of CYB3702 and CYB373 products can be customized, and the flange size shall be specified when ordering.
8.2 When selecting anticorrosive CYB3704 products, pay attention to the compatibility of shell material and measuring medium.
8.3 When the product has the risk of being soaked or submerged, it must be explained when ordering.
8.4 When selecting strong corrosion protection products, the product shell and meter head shall be well protected, and these parts do not have strong corrosion resistance.
