a.From Q, inclusive up to but excluding Q, is ± 2% for T30 (From Q, inclusive up to but excluding Q, is ± 3% for T50);
b.From Q, inclusive up to and including Q is ± 5%;

 

 

 

 

Suggest to install the UL-DW-PLUS intelligent 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), the ultrasonic flow meter for water surface should face right upwards (or right ahead), and it cannot have any deflection from water meter outlet axis;

The installation location of the static water meter 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 ultrasonic flow meter for water;

The intelligent water meter and pipeline should be connected by pipe fitting, sealing gaskets and connecting nuts (the connections).
