Installation requirements
The water meter must be installed horizontally, so that the meter’s degree number faces upward, and the arrow direction is the same as the water flow direction.
The pipeline must be flushed before the water meter is installed.
The water meter must be installed in the surrounding dry environment for easy disassembly and maintenance. It is recommended to install it in a dedicated water meter box. Valves must be installed before and after the water meter.
