Flowmeters

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.

What to include in your inquiry

These details let us quote the right item the first time.

  • Fluid and its state (liquid, gas or steam)
  • Line size and pipe material
  • Flow range: minimum, normal and maximum
  • Operating pressure and temperature
  • Output or protocol (4-20 mA, HART, pulse, Modbus)
  • Hazardous-area classification, if any

Frequently Asked Questions

Can a magnetic flowmeter measure oil or gas?
No. The fluid must be electrically conductive, so magmeters work with water, slurries and most chemicals but not oil, gas or pure hydrocarbons.
What is the minimum conductivity?
Typically 5 µS/cm for standard meters, with some designs working lower. Demineralised water may need a special meter.
Does a magmeter need straight pipe runs?
Usually around 5 diameters upstream and 2 downstream, which is less than many other technologies.
Which liner should I choose?
Hard rubber for water, PTFE or PFA for chemicals and high temperature, and polyurethane or ceramic for abrasive slurries.
What should I send for a quotation?
The model, or size, fluid, conductivity, flow range, pressure, temperature, liner, electrodes, output and quantity.
