The ABB Electromagnetic Flowmeters FEP611 and FEP631 are advanced full-bore magnetic
flowmeters designed for accurate and reliable flow measurement of conductive liquids in
industrial process applications. Manufactured by ABB, these flowmeters deliver
high-performance measurement capabilities with excellent accuracy, long-term stability, and
minimal maintenance requirements.
The FEP611 and FEP631 series are part of ABB’s ProcessMaster electromagnetic flowmeter
range, engineered to provide dependable flow monitoring in water treatment, chemical
processing, power generation, food & beverage, and industrial utility applications. Using
Faraday’s Law of Electromagnetic Induction, these meters accurately measure the flow rate of
conductive liquids without moving parts, ensuring low pressure loss and high operational
reliability.
The compact transmitter design, intuitive user interface, and advanced diagnostic capabilities
simplify installation, commissioning, and maintenance. With multiple liner and electrode material
options, the FEP611 and FEP631 flowmeters are suitable for aggressive chemicals, corrosive
media, and demanding industrial environments.
