MWN propeller water meters are designed to measure the consumption of significant amounts of cold water at a temperature of up to 50°C or hot water at a temperature of up to 130°C, at a maximum operating pressure of up to 16 bar (MAP16). Water meters are used in water transmission pipelines, in multi-family buildings, industrial facilities and public utility buildings. Installation in horizontal piping with the counter pointing upwards (H) or sideways (V) and in vertical pipelines with the counter pointing sideways (V). MWN water meters are available as standard with a six-roller counter (IP65 or IP68) and with a painted cast iron body. Water meters are adapted to work in remote data transfer systems (AMR).
