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.
Terms of use
Water temperature: cold water meter water temperature ≤40℃ (hot water≤90℃) and not lower than 0℃ Pressure: ≤1Mpa
Maximum allowable error
In the lowest area from including the minimum flow rate (qmin) to excluding the decomposition flow rate (qt) is ±5%
In the range from including the decomposition flow rate (qt) to including the overload flow rate (qs), the highest Area is ±3%
