The Flow Error Curve:
From Q1  inclusive up to but excluding Q2  is ± 2% for T30 (From Q1  inclusive up to but excluding Q2  is ± 3% for T50); 
From Q2  inclusive up to and including Q4  is ± 5%;


Structure&Dial Design:

Suggest to install the UL-DW water meter at U5 D3 (Straight pipe before the water meter at 5D,  after the water meter at 3D);
water flow should be in the same direction with the arrow on water meter main case; if installed horizontally (or vertically),
water meter surface should face right upwards (or right ahead),and it cannot have any de ection from water meter outlet axis;
The installation location should be protected from sunlight, freezing, pollution and water drown for    easy removing and cannot 
be installed near the inlet and outlet of the pump;
Flush the pipe work thoroughly to clear all   impurities before installing the water meter; The water meter and pipeline should be
connected by pipeitting, sealing gaskets and connecting nuts (the connections) .
