1. The product function introduction1.1 Basic function  Standard of implement

The design, production and instrument of RV-100 series Electromagnetic Flowmeter Converter implement<JJG-1033-2007 Electromagnetic Flowmeters>.

     Low-frequency square-wave exciting,exciting frequency:1/16 power frequency,1/20power frequency,1/25 power frequency;

     High-frequency square-wave exciting,exciting frequency:1/2 power frequency(for grouting liquid measure);

     Exciting current can be selected for 125mA,187.5mA,250mA,

     No need to add empty pipeline measurement, and can measure continuously, alarm by fixed value;

    Current speed range:0.1 --- 15m/s,current speed resolution:0.5mm/s;

     AC high-frequency switching power,range of voltage:85VAC --- 250VAC;

     DC 24V switching power,range of voltage:20VDC --- 36VDC;

     Network function:MODBUS,HART communication interface(choose);

     Chinese or English displaying mode, (other languages can be set);

     Three integrator gross inside, respective register: Forward gross, reverse gross and minus value gross.

 

1.2 Especial function

     Recording time when power turn-off, to record power broken time of instrument system automatically and recruit to count the missing flux;

     Recording function of hour gross, to record the flux gross by hour, fit for timed measure;

    Infrared handing telecontrol keyboard,all the functions of far-untouched controlling converter.

 

1.3 Normal operating conditions

Ambient Temperature Ranges: -10/+60

Relative Humidity:5%-90%;

Power Supply: 85-250V,45-63Hz ( single-phase AC).

Dissipation Power: <20W( After connecting sensor).

 

1.4 Type of connecting with sensors

l           The integrated circinal shells: circinal shells, shells connect with the flange directly, explosion-proof;

l           The integrated squared shells: squared shells, shells connect with the flange directly;

l          The split squared shells: squared shells (hang on the wall), Signal converters connect with cable of sensor;

 request of relative sensor

       Sensitivity of sensor signal: under 1m/s, output 150µV -00µV;

For RV-100 magnetic flowmeter signal converters, there are four currents of 62.5 mA in exciting loop, which make up of 250mA, and every 62.5mA is controlled by one 20 ohm exact resistanceact . So user can choose different exciting current by changing the number of exact resistance.

The current will be 250mA when the signal converters leave factory, as such, if there are three exact resistance, the current will be 187.5 mA; iftwo, 125mA;

 Resistance of sensor exciting coil

                 250mA exciting current:50-60ohm            

                       187mA exciting current:60-80ohm

                                   125mA exciting current:100-120ohm
