1.2 Scope of application

Electromagnetic flowmeter is composed of sensor and converter,and works based on Faraday'slaw of electromagnetic induction.The product has almost no pressure loss,and the measurement is not affected by the changes of fluid density,viscosity, temperature,pressure and conductivity,and the range ratio is large.Therefore, it is the most ideal instrument for measuring the volume flow of conductive liquid.

1.3Workingprinciple

The measurement principle of electromagnetic flowmeter sensor is based on the Faraday's law of electromagnetic induction.One pair of detection electrodes are installed on the tube walls perpendicular to the axis of the measuring tube and the line of the magnetic field.When the conductive liquid moves along the axis of the measuring tube,the induced potential is generated as the conductive liquid cuts the magnetic line. The induced potential is detected by two electrodes on the measuring tube.The potential value is:

E=KBVD

Where:E-Induced potential K - Instrument constant B-Magnetic induction intensity -Average flow velocity in the cross section of measuring tube D- Inside diameter of measuring tube

During flow measurement,the fluid will flow through the magnetic field perpendicular to the flow direction.The flowing of conductive fluid inducts a potential directly proportional to the average flow velocity. Therefore,the measured flowing liquid is required to have the conductivity above the minimum limit.The induced voltage signal is detected by two electrodes and sent to the converter through a cable. After signal processing and related operation,the cumulative flow and instantaneous flow are shown on the display of the converter.

1.4Instrument Characteristics

1) There is no choked flow and moving parts in the measuring tube,so no additional energy loss and blockage will be caused,and the energy-saving effect is remarkable,especially suitable for the measurement of liquid-solid two-phase flow such as sewage,mud,ore pulp, coal water slurry and pulp.

2) Only the lining and electrode are in contact with the measured medium.As long as the lining and electrode materials are reasonably selected，good corrosion resistance and wear resistance can be achieved. Therefore,various chemical solutions such as strong acid and strong alkali can be measured.

3) The installation requirements are low,with only 5D for the front straight pipe section and 2D for the rear straight pipe section (D is the internal diameter of the selected instrument).

4) The measurement accuracy is high,up to 12 % of the indicated value,and the flow in the forward/reverse directions can be measured.

5）The instrument has a variety of excitation modes,is not easily disturbed by power frequency and fluid noise,and works stably and reliably.

6)The power consumption of the instrument is small,less than15VA.

7) The converter has good interchangeability,and the accuracy can be achieved without re-calibrating the real flow.

8) The measuring range is wide,up to 1500:1. 9) The electrode has a unique double sealing mode of conical surface seal and line seal to ensure no leakage. 10）The EMC (electromagnetic compatibility) index of flowmeter meets the requirements of IEC61326-1 standard. 11) The input impedance of the converter is greater than l0l2 ohms,to effectively prevent the influence of scaling on the sensor and suitable for measuring conductivity media { >= } 2 \mu { S } / {cm } ： 12）The functions of self-diagnosis,alarm and output,such as empty pipe detection,excitation drive alarm and storage error,are provided. 13）Explosion-proof mark:Exia/db eb Ic T4\~T6 Ga/Gb

5.SelectionofElectromagnetic

5.1Selection of instrument diameter

5.1.1Selectionofsensordiameter

The selected instrument diameter is not necessarily the same as the diameter of the connecting pipe,but should be determined according to the flow rate of the pipeline.

Generally speaking,the pipeline flow rate of 5 { m / s } ~ 5 { m / s } is the economic flow rate,and the sensor diameter is the same as the pipe diameter.Unless the medium is less abrasive and made of wear-resistant materials,it is recommended that the long-term working flow rate should not exceed { 7 m / s }

For fluids containing substances that are easy to adhere,precipitate and scale,it is suggested that the common flow rate should be not less than 2 { m / s } ,anditis better to increase it to 3 { m / s } ~ 4 { m / s } or above,so as to play the role of self-cleaning and preventing adhesion and precipitation.

For fluids with strong abrasion such as ore pulp,the common flow rate should be lower than 3 { m / s } to reduce the abrasion to the lining and electrode.

When measuring low conductivity medium with conductivity of 2 \mu { S } / {cm } { ~ } 1 0 \mu { S } / {cm } ,lowflowrate { 5 m / s ~ } 1 ~ { m / s } ）should be selected as much aspossible,because the flow noise will increase with the increase of flow rate, and the output will shake.

(1) The instrument diameter is <= 3 0 0 ,and the accuracy class can reach 2; Diameter is > 3 0 0 ,and accuracy class is 5 (if better than 5,please negotiate with the company to order)

(2)Fortheselectionofinstrumentdiameter,pleaserefer totheFlowRangeTable belowandtheDiameter,FlowRate andFlow Comparison Table in the appendix.

5.1.2 The diameter of the selected sensor is the same as that of the connected process pipeline

The diameter of the selected sensor is the same as that of the connected process pipeline,which is convenient to install.

5.1.3Thediameterof theselected sensoris different from that of the connected process pipeline

This option is applicable in the following situations:

A.The flow rate in the pipeline is low,and the process flow is relatively stable.In order to meet the requirements of the instrument for the flow rate range, the flow rate is locally increased in the instrument part, thediameter of the sensorisselectedto be smallerthan that of the process pipeline,and a reducer is added before and after the sensor.

B.Considering the price,for large-diameter electromagnetic flowmeter,the larger the diameter, the higher the price.When the flow rate in the pipeline is low and the process parameters are stable,the sensor with smaller diameter can be selected,which can not only make the instrument run in better working condition,but also reduce the purchase cost.

5.1.4Precautionsforinstallingreducer

In order not to affect the distribution of flow rate field too much and the measurement accuracy of the instrument, the central cone angle a of the reducer is not greater than 1 5 ^ { \circ } ,so that the reducer can be regarded as a part of the straight pipe section.

5.1.5Selectionofdiametercode

The expression of the diameter of MF electromagnetic flowmeter is three digits:the first and second digits of DN and the number of zeros following the first two digits (unit: mm).

For example,code 1oo indicates a diameter of 1 0 {mm } ；code101 indicatesa diameter of 1 0 0 {mm } ；code 102 indicates a diameter of 1 0 0 0 \ {mm } .DN2.5diameter code is special,the expression is O25,and DN125 expression is 121.

5.2Selection of lining materials

The lining material isselected according tothe corrosiveness,abrasionand temperature of the medium to be tested.The applicable performance of common lining materials is shown in the following table:

5.3Selectionofelectrodematerials

The selectionof electrode materials should be determined by the user according to the corrosiveness of the measured medium,and the user can refer to the relevant anti-corrosion manual.

5.4SelectionofIPGrade

According to the national standard GB4208,the shell IP grade of instruments can be divided into the following categories:

IP65:Water spraying type allows the faucet to spray water on the instrument from any direction,with the water spraying pressure of 3 0 { { k P a } } ,the water output of 12.5L/Min and the nozzle distance of 3 { m } from the instrument.

IP67:Immersed instrument can be completely immersed in water(lmunderwater) ina short time,with duration of 3 0 { m i n }

IP68:Submersible type can work underwater for a long time (5m underwater),and the maximum depth shall be negotiated with the manufacturer.

IP grade shall be selected according to the above requirements and actual conditions of instruments.

When outdoor protective box is not used,the measuring instrument with IP65 or above should be installed in the shade.

Avoid direct sunlight,and pay special attention when using in hot areas.

Avoid direct exposure to theclimate.

If the instrument is installed under the ground andoftenflooded,orif the instrumentisinstalled on the ground with high air humidity or exposed to steam, it is advisable to choose the split type,sensor IP68 and converterin the protective box or indoors.

5.5SelectionofCable

The connecting cable between the sensor and the converter isa special multi-shieldedcable.The cable length in the model& specification table refers to this cable,and its length is related to the conductivity of the medium.The maximum length is 5 times of the minimum conductivity, but generally does not exceed 1 0 0 { m } (if the length is exceeded, it will be supplied after negotiation with the manufacturer).The connecting cable between the sensor and the converter generally requires iron pipe for protection when it is installed on site

Cable connection is not allowed.In case of accidental breakage or extension，please purchase a special junction box with sealant to extend the cable.

5.6 Selection ofFlange

Except in special circumstances,metric flanges should be generally selected,and the companion flanges are also made in metric system.Flanges meet the national standard GB9119,and common specifications can be found in Appendix 1.Special orders can be made for all special flanges and those exceeding the instrument pressure rating.When ordering,if companion flanges need to be installed,the instrument connecting pipe size (outer diameter \* wall thickness) should be provided.

5.7Selection of junction boxseal

The outgoing line sealing method of junction box is \mathbf { M } 2 \mathbf { 0 } ^ { * } \mathbf { 1 } . 5 sealing sleeve to seal the cable.The commonly used \mathbf { M } 2 \mathbf { 0 } ^ { * } \mathbf { 1 } . 5 sealing sleeve has the same codes1and5intheselectiontable,butthedifference is that code1 requires the cable to be connected and filled with sealant before the product leaves the factory,while code 5 requires the user to complete these tasks.

5.8 Selection of earthing ring

As the induced signal voltage of electromagnetic flowmeter is very small and susceptible to external noise or other electromagnetic signals,an earthing ring is used. The function of the earthing ring is to form a space shielding the external interference by earthing the shell of the flowmeter and hence increase the measurement accuracy.(If users use non-metallic pipes,they must install earthing rings,which should be indicated when ordering，and the earthing ring option should be selected).Even for metal pipes,the instrument should be reliably and independently earthed with earthing resistance less than10 ohms.The installation methods of the instrument under different conditions are shown as follows:

B.Earthing of plastic pipe

5.9 Determination of Operating Environment

Working environment refers to the environment around the instrument,which can be divided into general workplaces and dangerous workplaces.

General workplace refers to a safe place where there is no combustible gas or explosive substances,and the working environment temperature is below 6 5 ^ { \circ } { C } and the upper limit of medium temperature is divided into three types: 8 0 ^ { \circ } { C } 1 4 0 ^ { \circ } { C } and 1 8 0 ^ { \circ } { C } .The instrument can be integrated or split (if the medium temperature is higher than 8 0 ^ { \circ } { C } ,the split type is recommended).

Dangerous place refers to a place where there are combustible gases and explosive substances.The working environment temperature should not be higher than 6 0 ^ { \circ } { C } ,and the medium temperature should not be higher than 8 0 ~ 1 3 0 ^ { \circ } { C } (depending on the explosionproof temperature grade,see the type spectrum for details).

The working temperature of the converter should not be higher than 6 5 ^ { \circ } { C } ：

The shell and flange of the sensor body are welded integrally,which can meet the working environment mentioned above.
