ZF-LD Series Electromagnetic Flowmeter
The ZF-LD series electromagnetic flowmeter measures the volumetric flow of conductive liquids with a conductivity greater than 5 μS/cm, based on Faraday's electromagnetic induction law. It is suitable for general conductive liquids, corrosive substances (acids, alkalis), and slurry or pulp. Common applications include industries such as petroleum, chemicals, metallurgy, textiles, paper, environmental protection, food, and municipal management.
