Product overview of electromagnetic flowmeter

LDE split (integrated) electromagnetic flowmeter consists of two parts: sensor and converter. It is based on Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive liquids with a conductivity greater than 5 μS / cm. It is an inductive meter that measures the volume flow of conductive media. In addition to measuring the volume flow of general conductive liquids, it can also be used to measure the volume flow of highly corrosive liquids such as strong acids and alkalis, and uniform liquid-solid two-phase suspension liquids such as mud, ore pulp, and pulp. Widely used in petroleum, chemical industry, metallurgy, light textile, papermaking, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other fields to measure diesel oil, lubricants, heavy oil and other oil-free liquids with high precision.
Product features of electromagnetic flowmeter
