The LDB electromagnetic flowmeter consists of two parts: a sensor and a converter. It is an inductive instrument used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm, based on Faraday's law of electromagnetic induction. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp. Widely used for flow measurement in industrial sectors such as petroleum, chemical, metallurgy, textile, papermaking, environmental protection, food, as well as municipal management, water conservancy construction, rivers and other fields.
