Promag 200 – The flowmeter for corrosive liquids

Electromagnetic flow measurement with efficient loop-powered technology for the chemical industry

Promag 200 is the first electromagnetic flowmeter that can be seamlessly and flexibly integrated into process control systems. The HART, PROFIBUS PA and FOUNDATION™ Fieldbus communication protocols supported by the standard device version gives engineers greater flexibility in designing the measuring point.


  • Broad range of applications – reliable measurement of all conductive liquids (≥20 μS/cm) such as water, acids, alkalis, solvents or pastes

  • Efficient loop-powered technology (4–20 mA) – high measuring performance in standard applications comparable with four-wire devices

  • Industry-optimized flowmeter – meets all the relevant requirements of the chemical industry, such as SIL, Ex approvals or diagnostics according to NE107

  • Seamless system integration – cost-saving installation and maximum safety during operation

Attractive loop-powered technology with several advantages

Optimized for the chemical industry, loop-powered (two-wire) technology offers several advantages over four-wire devices: the installation costs are lower and the devices can be more easily integrated into the existing infrastructure. Standard-practice installation. The intrinsically safe ATEX concept enables a greater range of applications and greater flexibility in hazardous areas.
