Electromagnetic Flow Meter
1. Basic Functions OF Electromagnetic Flow Meter
Head Converter Low frequency excitation, 2.5Hz Excitation current 125mA or 250mA No need of additional electrode empty-pipe measuring function, continuous measuring, pre-set value alarm. Velocity measuring range: 0.1----15M/s, velocity resolution: 0.5mm/s. AC high frequency on-off power, voltage range: 85VAC---250VAC DC 24V on-off power, Voltage range: 20VDC --- 36VDC Internet function (Optional): MODBUS, Hart, GPRS, PROFIBUS. Chinese or English Display and operation (Other language customized accepted). Built-in 3 kinds of accumulating - calculators, can separately record: positive-direction accumulating, negative-direction accumulating, total value difference of positive-negative. 2. Working Conditions of Electromagnetic Flow Meter Head Converter Ambient temperature: Split type -10 to +60 Deg.C Relative humidity: 5-90% Power supply: Single-phase alternating current 85-250V, 45-63Hz Dissipated power: less than 20W (After connected with Transmitter pipe). 3. Overall Dimensions of Electromagnetic Flow Meter Head Converter
Note: 1) Round shell compact type: round shell, shell connected directly with transmitter & sensor’ flanges, Square shell remote split type: wall mounted square shell, converter connected with sensor by cables. 2) Mating transmitter & sensor flanges nominal diameter (mm) : DN6-3000MM 4. Mating Transmitter & Sensor Requirements of Electromagnetic Flow Meter Head Converter Signal sensitivity of sensor: when 1M/s velocity, sensor output 150-200 µV. Excitation circuit adopts 125mA current, can work with 30-110 ohm Sensor excitation coil resistance. 5. Total measurement accuracy of Electromagnetic Flow Meter Head Converter
6. Built-in Communication Remote output SYSTEM. Internal built-in GPRS DTU module, can work with data center to achieve TCP/IP bi-direction communication, by DTU software and user devices and RS232/485 to create transparent and reliable data transit, transiting the data to management center, achieve real time monitoring. Remote transmission system can get the flow converter’s data in any location that covered by GPRS signals and net., sampling period can be adjustable from 10s to several minutes. Date management center timely stores the data into data base. By this system, although be in different location far from measurement field, also can readout and collect the data from every monitoring spot, really achieve remote monitoring and data share function.
