Installation requirements
★ Clean the foreign matter from the inside pipe.
★ This kind of water meter couldnt be spoiled in the hot sun,humid, freeze,chemistry,electronic pollution, easy for dismantle,reading, and credit the user card.
★ Horizontal install, the direction mark should in accordance with the flow direction. Leave length about 6-12 times of the pipe diameter at the front of the water meter, and length about 4-6 times of the pipes diameter at the back of the water meter for the accuracy measurement.
