Description of DN300 Electromagnetic Flow Meter

Description :

　　This product has measurement value power-off protection and air traffic control alarm function. The flow direction of the fluid can be set, so the installation of the sensor is not limited by the direction of liquid flow and can achieve bidirectional flow measurement.

　　1、 Technical parameters:

　　Nominal diameter (mm) (special specifications can be customized)

　　Pipeline type PTFE lining: DN10~DN600

　　Pipeline rubber lining: DN40~DN2200

　　Flow direction: positive, negative, net flow

　　Range ratio: 150:1

　　Repetitive error: ± 0.1% of the measured value

　　Accuracy level: Pipeline type: 0.5 level, 1.0 level

　　Temperature of the tested medium: ordinary rubber lining: -20 to+60 ℃; High temperature rubber lining: -20 to+90 ℃

　　PTFE lining: -30 to+100 ℃; High temperature PTFE lining: -20 to+180 ℃

　　Rated working pressure: (high pressure can be customized) DN10- DN150: ≤ 1.6MPa; DN200－DN350：≤1.0MPa

　　DN400－DN1000：≤0.6MPa； DN450－DN2200：≤0.25MPa

　　Flow velocity range: 0.1-15m/s

　　Conductivity range: The conductivity of the measured fluid is ≥ 5 μ s/cm

　　2、 Characteristics:

　　1. Applicable medium: any conductive liquid.

　　2. Not applicable to media: non-conductive liquids, gases, and vapors.

　　3. Negative pressure pipelines cannot be used.

　　4. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity.

　　5. The requirement for a straight pipe section with no obstructed flow components and no pressure loss inside the measuring tube is low. It has unique suitability for measuring slurry.

　　6. There are no movable parts or flow blocking components inside the pipeline, and there is almost no additional pressure loss during measurement.

　　7. It has self checking and self diagnostic functions.

　　8. The range can be modified online according to the actual needs of the user on site.

　　3、 Installation:

　　1. It should be installed indoors in a dry and ventilated area. Avoid installation in areas with high ambient temperatures, avoid strong vibrations, and try to avoid equipment with strong magnetic fields. Such as large motors, transformers, etc. Avoid installation in environments with corrosive gases. The installation location should be convenient for maintenance, which is the environmental condition to ensure the normal operation of the transmitter.

　　2. Valves and bypasses should be installed at both ends of the electromagnetic flow transmitter.

　　3. In order to ensure that the measuring tube of the electromagnetic flow transmitter is filled with the measured medium, the inverter is installed vertically with a flow direction from bottom to top. Especially for liquid-solid two-phase flow, it must be installed vertically. If only horizontal installation is allowed on site, it must be ensured that the two electrodes are on the same horizontal plane.

　　4. To avoid interference signals, the signal between the transmitter and the converter must be transmitted using shielded wires.
