Product Introduction

L-mag (B) Electromagnetic Flow Converter Instruction Manual

I. The product function introduction

1.1 Basic function

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

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

3)Exciting current can be selected for 125mA、187.5mA、250mA、500 mA;

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

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

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

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

8)Network function：MODBUS, GPRS, PROFIBUS, HART communication interface(optional);

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

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

1.2 Especial function

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

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

3) Infrared handing telecontrol keyboard， all the functions of far-untouched control converter.

1.3 Normal operating conditions

1) Ambient Temperature Ranges: fission –10+60℃; Relative Humidity：5%～90%;

Power Supply: 85～250V, 45～63Hz (single-phase AC). Dissipation Power: <20W(After connecting sensor).

1.4 Characters of sensor

1)All plastic structure, reliable sealing, non-moving parts, non-resistance parts, anti-corrosion, simple construction and reliable running;

2)Accuracy will be not influenced by medium temperature, pressure, viscosity, density and other physical parameter changes etc. As long as the conductivity of medium more than 20uS/cm, measurement will be not influenced by the changes of conductivity.

3)Advanced low frequency square wave constant current excitation with the characters of stable performance, reliable running, strong anti-interference capacity, and sensor and converter are interchangeable.

4)Suitable for measuring solid-liquid two phase mediums, like the conductive slurry with suspended solids, particles or fiber etc, also it is good to measure the flows of mud, paper pulp, ore pulp and chemical fiber etc.

5)Suitable for open channel, covered channel and river etc, suitable for round, trapezoidal, rectangle and other shapes’ channels. The measurement will be not be influenced by river rise, tides and changes of downstream water level etc.

6)Low requirement to upstream and downstream straight channel, short construction period and low installation and construction cost.

7)Using simulation sensors( shunting model) to expand flow velocity range;

8)Wide flow range, the max velocity could be any set from 1m/s to 10m/s, output signal and flow will be liner relation.

9)Not only with standard signal output like 0~10mA.DC or 4~20mA.DC, but also 0~10kHz frequency output. Output signal could be used to indicate the flow, record, totalize and regulation controls by mating operation with DDZ-Ⅰmodel, DDZ-Ⅲ model, Ⅰseries and EK series instruments.

10)Since above characters of the sensor, it is widely used to chemical, fiber, metallurgy, fertilizer, paper pulp, water supply and drainage, waste water treatment and irrigation industries etc.
