Electromagnetic flowmeter

Specific for installations with “0 diameters” near curves, fittings etc …

Dn 40 ÷ 800 mm

Acuracy: ± 0.2% ± 0.5%

ABS sensor and lining

Battery powered, 6 years battery life


Battery-powered RBKmag flowmeters do not require external power supply, therefore they are a valid alternative to conventional mechanical measuring systems and in isolated applications without power supply. RBKmag thanks to the particular internal geometry is less influenced by the proximity of disturbing elements such as fittings, curves etc. and can therefore be installed at “ZERO DIAMETERS”. The RBKmag meter is suitable for use with a wide range of conductive liquids, also chemically aggressive, thanks to the possibility of selecting the most suitable electrode material for the application.
