Electromagnetic flowmeter is induction gauge to measure the volume flow of the conducting object. Electromagnetic flowmeter of LDE model, plug-in type is a new pattern Electromagnetic flowmeter that based on tube type electromagnetic flowmeter. It keeps the advantage of of tube type electromagnetic flowmeter and also aims at the difficulties and great expense of installing the tube type electromagnetic flowmeter on the big tubes, according to the NIKURADS theory, measuring the mean flow rate through electromagnetism which finally gets the volume flow of the fluid. Especially after the hot-topping and mounting with pressure techniques being adopted, plug-in electromagnetic flowmetercan be installed without stopping the car or water flow, and it can also be installed in castiron tube, cement tube and PE tube. The plug-in electromagnetic flowmeter provides the measurement of the volume of the flow with a new method.
Characteristics:
No moving or resistance parts inside the tube, seldom additional pressure loss in measurement.
Results of measurement have nothing to do with flow velocity distribution, fluid-power pressure, temperature, density, viscosity or other physical parameters.
Alter the range according to the customers' requirements on line.
High definition LCD display, operation all in Chinese menue, easy to use, simplicity of operation, understandability.
Adopt SMD parts and surface paste( SMT circuit is of high reliability)
Adopt 16 bit insertion micro processor, high operating rate, high precision, programmable frequency, LF rectangular wave excitation.
Degital quantity dispose, high antijamming capability, reliable measurement, high precision, range of the flow measurement can reach 150: 1.
Ultra-low EMI switch power supply which enables the line-voltage variation in a wide range, great resistance to EMC.
Three integrator inside which can discriminability show forward direction accumulative total volume and D-value integrating volume.
RS485, RS232, Hart and Modbus digital communicating signal output.
Function of self-checking.
Operating principle
Theory of electromagnetic flowmeter is based on Faraday's electromagnetic induction law. Tube of flowmeter is a kind of lining insulating material, none permeability alloys tube. Two electrode are fixed on the measuring tube along the tube diameter direction through tube wall. The electrode tip is abreast to the lining. When both side impulsing the excitation, magnet exciting coil will produce a operating magnetic field whose density is B through the direction that is vertical to measure tube axis. At this moment, if there's certain volume of specific conductance fluid going through the measuring tube will incise the magnetic line of force which produce the electromotive force(E). Electromotive force is directly proportional to density B multiply internal diameter of measuring tube(d) and mean flow rate. Electromotive force produced from electrode goes through cable and then reach in converter. Converter will show the volume of the fluid and output the pulse, imitate signals of electric current which control and adjust the flow after dispose these signals.
