Electromagnetic Flowmeters

Electromagnetic flowmeters measure the flow of conductive liquids from the voltage induced as the liquid passes through a magnetic field, with an open bore and no pressure loss. Seven Star LLC, an independent supplier in Muscat, supplies magmeters from ABB, Endress+Hauser, KROHNE, JUMO, Yokogawa, Rosemount, Siemens, KOBOLD, Badger Meter, Tecfluid and Tokyo Keiso to customers in Oman and the GCC.

Types of electromagnetic flowmeter in this category

Process magmeters such as the ABB ProcessMaster FEP300, FEP500, FEP610 and FEP630, Endress+Hauser Promag P 300 and P 500, KROHNE OPTIFLUX 2300, 4100 and 4300, Yokogawa ADMAG AXG and AXW and Rosemount 8700 serve water, chemicals and slurries. Hygienic meters like the ABB HygienicMaster and Endress+Hauser Promag H 300 suit food and beverage. Compact and insertion meters such as the JUMO flowTRANS MAG, KOBOLD MIM, GF Signet 2551 and Tecfluid FLOMID cover smaller lines and retrofits.

How to select a electromagnetic flowmeter

Confirm the liquid is conductive (typically above 5 µS/cm). Define line size, flow range, pressure, temperature and process connection. Choose liner and electrode materials for the fluid (PTFE, PFA, rubber, ceramic; stainless, Hastelloy, titanium, tantalum), then outputs, power supply and remote or compact transmitter.
