Overview
The ZFG series integrated electromagnetic flow meter consists of a
ZFG-type electromagnetic flow meter sensor and a ZFH series signal
converter, which are combined as a single unit. The signal
converter meets the IP67 protection requirements. The ZFG
integrated electromagnetic flow meter is primarily used to measure
the volumetric flow rate of conductive liquids such as acids,
alkalis, salt solutions, pulp, slurry, or liquid-solid two-phase
media. It is widely applied in industries such as chemical
engineering, mining and metallurgy, water supply and drainage,
sewage treatment, food, papermaking, sugar refining, and port
dredging.
The working principle of electromagnetic flow meters is based on
Faraday's law of electromagnetic induction. In an electromagnetic
flow meter, the conductive medium inside the measuring tube acts
like the conductive metal rod in Faraday's experiment. Two
electromagnetic coils at the upper and lower ends generate a
constant magnetic field. When conductive medium flows through, an
induced voltage is generated. The two electrodes inside the pipe
measure this induced voltage. The measuring pipe achieves
electromagnetic isolation from the fluid and measuring electrodes
through a non-conductive lining (such as rubber or Teflon).
