INSTALLATION:
  • 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 deflection from water meter outlet axis;
  • The installation location should be protected from sunlight, freezing, pollution and water drown for easy removing and cannot be install near the inlet of the pump;
  • Flush the pipe work thoroughly to clear all impurities before install the water meter;
  • The water meter and pipeline should be connected by pipefitting, sealing gaskets and connecting nuts (the connections). The water meter should not be removed by force to prevent the damage to the water meter cover.
