L-mag Signal Converters for Electromagnetic Flow meters are the only devices for processing all the signals from the sensors of electromagnetic flow meters as the digital data and display the output results of the system in numerical ones and transfer the results to control system for further processing and controlling flow systems. L-mag Signal Converters are the newest developed high-tech imbedded computerized devices for electromagnetic flow-meter sensors in any sized diameters. The converters can be linked to any kinds of electromagnetic flow-meters sensors for real uses either in industrial and civil ones with high reliabilities and in high accuracy. 1.1 L-mag converters have special characteristics bother in structure and principles for users as follows: Programmable low frequency exciting in rectangular pulse with flow measurement reliabilities and low power loss. With embedded 16-bit micro-controller processing the data at high speed and in precise accuracy. Full processing digitally, high noise resistance and high stability in measurement and accuracy having 1500:1 ratios in the range of flow rate measurement. Equipped with switching power supply in the lowest EMI and well operated in the condition of unstable voltage of electrical supply circuits. With the High abilities resisting EMC. Displayed all in Chinese in operating manus that can be run conveniently, operated simply and learning and understanding easily by operators. LCD display in high resolution. With bi-directional way measurement having the power accumulating total flow rate, all having bi-directional outputs of electrical currents and frequencies. Three inner accumulators for displaying the forward accumulated value, reverse accumulated and deference values respectively. Output digital signals for RS485 and RS232C communication. Having capability to measure conductivity of detected media and checking the empty of the measured pipes. Big margin of constant exciting currents can be gotten by the converters that can be linked to and equipped with deferent sensors of electromagnetic flow meters made in deferent companies. Having self-testing and self-diagnostic functions. Using the SMD devices and SMT Technology to make the circuits having higher reliabilities in the system. Inner equipped timer that can work when the electricity is gone and can memorize 16 times when the electricity had been stopped.
