The FSM4000 is a high-performance electromagnetic flowmeter from ABB designed for demanding industrial environments. It can accurately measure the flow rate of various electrically conductive liquids, slurries, pastes and sludges. The FSM4000 flowmeter is suitable for chemical, power, oil and gas, paper, mining and metallurgy, food and pharmaceutical process industries, especially suitable for high solid content, high pulp concentration, pulsating flow or other noisy applications.

The flow meter design offers a variety of industry-specific linings, electrodes and sizes to meet different needs. Its powerful transmitter is easy to use and provides a stable signal output. The FSM4000 also features digital signal processing (DSP) and zero stability to ensure long-term stability and accuracy, as well as enhanced diagnostic capabilities and monitoring of coil and electrode circuits and magnetic fields to improve operational stability.

Technical parameters include:
Nominal measuring diameter: DN 3 to 1000 (1/10 to 40 inch)
Nominal pressure rating: PN 10 to 40, ASME CL150, 300
Process connection: Flange according to DIN/EN, ASME standards
Lining material: PFA, PTFE, hard rubber, soft rubber, carbonized ceramic
Communication output: HART, optional PROFIBUS PA, FOUNDATION Fieldbus
The FSM4000 flow meter typically has an accuracy of ±0.5% reading and is suitable for fluid temperatures ranging from -40°F to 266°F (-40°C to 130°C), with some models available up to 180°C (356°F). It also has hygiene certifications, such as 3A and EHEDG, for the food hygiene industry.
