The PTFE lined electromagnetic flowmeter measures flow rate based on Faraday's Law of Electromagnetic Induction. This product is mainly used to measure volumetric flow of conductive media. It adopts 304 stainless steel body, PTFE lining and 316L electrodes, featuring low pressure loss and wide measurable flow range. The ratio of maximum flow to minimum flow is generally above 20:1.

Application Fields

The PTFE lined flowmeter supports a wide range of industrial pipe sizes from DN10 to DN2000. The output signal has linear relation with measured flow with high accuracy. It can measure fluid flow of acid, alkali, salt solution, water, sewage, corrosive liquid, mud, ore slurry, pulp and other media with conductivity ≥5μs/cm. It is widely used for flow measurement in chemical industry, metallurgy, textile, papermaking, environmental protection, food industry, domestic sewage, industrial wastewater, cooling water, waterworks, municipal administration, water conservancy construction, river dredging, building water supply metering and other fields.
