Remarks: For DN40~DN80, the lining protective ring is 2mm, so the total length of the flow meter shall be
increased by L+4mm. For DN100~DN300, the lining protective ring is 0.5mm, so the total length of the flow
meter shall be increased by L+1mm; total length (L) tolerance is ±3mm, total height (H2) tolerance is ±5mm
