 A body electromagnetic flowmeter: LDE series of electromagnetic flowmeters are widely used in chemical, steel, coal, mining and metallurgy, oil, mining, petrochemical, papermaking, environmental protection, sugar, pharmaceuticals, food, irrigation, water supply and drainage and port dredging and other fields, can accurately measure the various acids, alkalis, salt solutions, raw water, cooling water, sewage, coal slurry, slurry, mud, slurry, pulp, syrup, liquid and a variety of drinks such as the conductive fluid and solid volume flow of the liquid two-phase body. 

 LDE series electromagnetic flowmeter has two kinds of combination of a size and sub-size output stage were taken electrically isolated, can easily posterior instrumentation supporting records, control and regulation, and the traffic. At the same time, the flow meter with rs485 communication interface, can be interconnected with the computer. The flow of water for each product according to the ordering requirements of the actual flow calibration, and usually do not make any adjustments can be put into use. 

 Electromagnetic flowmeter works LDE series of electromagnetic flowmeter for measurement of conductive liquids and slurries in closed conduits, volume flow, clean water, sewage, various acid-base salt solution, slurry, pulp, pulp and food liquids, etc. LDE series of electromagnetic flowmeter measurement principle is based on Faraday's law of electromagnetic induction; conductive liquid in a magnetic field, cutting movement of the magnetic field lines, the conductor EMF e: 

 e = kbvd 

 Where: k ----------- instrument constant 

 b ------------ magnetic induction 

 the average velocity of v ------------ measurement pipe section 

 d ------------ measurement of the pipe cross-section of the inner diameter
