Integrated Electromagnetic Flowmeters
Approved by：CE, SIL-3, ATEX Explosion-proof certification
The AFTLD-X Integrated Electromagnetic Flowmeter is an intelligent, high-performance instrument designed for the accurate measurement of conductive liquids and slurries in closed pipelines.
Built on Faraday’s electromagnetic induction principle, it offers high accuracy, excellent stability, and maintenance-free operation across a wide range of industrial applications such as water supply, wastewater treatment, chemical processing, food production, energy, and metallurgy.
The converter adopts advanced low-frequency or dual-frequency square-wave excitation and digital signal processing technology to ensure stable and precise readings even in low-conductivity or pulsating flow conditions.
