Electromagnetic flowmeter Product Overview: ZX-LDG intelligent electromagnetic flowmeter consists of two parts, the sensor and converter. Insert into the tube stage and two installation measurement forms. It is based on the work of Faraday's law of electromagnetic induction, used to measure the conductivity is greater than 5μS / cm conductive liquid volumetric flow rate, is a measure of the volume flow of conductive medium for induction meter. In addition to measure the volume flow of conductive liquid, it can also be used to measure the volume flow of homogeneous liquid-solid two-phase liquid suspension of acid and alkali and other strong corrosive liquids and slurries, pulp and paper pulp. Widely used in flow measurement in petroleum, chemical, metallurgy, textile, paper making, environmental protection, food industry and municipal administration, water conservancy construction, river dredging and other areas. How it works: According to Faraday's principle of electromagnetic induction, the measuring tube axis and the magnetic field lines perpendicular to the wall to install a pair of detecting electrodes, when the conductive liquid tube axis motion along the measurement, the conductive liquid cutting magnetic field lines generated EMF, the EMF detected by the two detection electrodes, the numerical size is proportional to the flow rate. E EMF sensor as traffic signals, transmitted to the converter, amplified, filtered transformed by a series of digital processing, using dot matrix LCD with backlight shows the instantaneous flow rate and cumulative flow. The converter has 4 ~ 20mA output, alarm output and frequency output and a RS-485 communication interface, etc., and supports HART and MODBUS protocol.
