For measuring the volume of cold water with a temperature of 30°C - 50°C or hot water with a temperature of up to 90°C passing through the meter, at a maximum working pressure of up to 16 bar (PN16). They are installed on horizontal sections of the pipeline with a scale up (Н↑) or to the side (Н→) and on vertical sections of the pipeline with a scale to the side (V). In the standard version, Smart C + water meters are produced in a brass case, with a low 8-roller drum counter mechanism (IP65), with SN+ anti-magnetic protection and can be used in remote data transmission (AMR) systems.
