LDG electromagnetic flowmeter

Description :

　　LDG electromagnetic flowmeter

　　The measurement results of this product are independent of physical parameters such as fluid pressure, temperature, density, viscosity, etc. It is displayed on a high-definition backlit LCD and operated through a full Chinese menu. It is easy to use, simple to operate, and easy to learn and understand.

　　1、 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, it is installed vertically and flows 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. It is not allowed to parallel signal cables and power lines in the same cable steel pipe. The length of signal cables should generally not exceed 30m.

　　2、 Technical parameters:

　　1. Provide display interfaces in both Chinese and English;

　　2. It can directly display the instantaneous flow rate, cumulative flow rate, percentage flow rate, and flow velocity in both forward and reverse directions according to the engineering unit;

　　3. There are 6 types of flow units to choose from (L/m, L/h, m3/m, m3/h, GPM, GPH);

　　4. 4~20mADC load 0~750, scale flow rate (upper limit of range) can be set arbitrarily;

　　5. By setting the pulse coefficient, each pulse can represent a certain volume flow rate, or output a 0-2kHz frequency signal proportional to the flow rate;

　　6. Provide traffic upper and lower limit reporting function;

　　7. RS485 interface, bidirectional communication. The working parameters of the flowmeter can be set and modified through the upper computer;

　　8. When the fluid is stationary, the zero point of the flowmeter can be automatically calibrated through the buttons on the panel;

　　9. Damping adjustment can be set within a range of 1 to 99 seconds;

　　10. Power supply voltage: 220VAC/24VDC type;

　　11. Environmental temperature: -20~60 ℃;

　　12. Protection level: IP65;

　　13. Explosion proof grade: ExdibIIBT4.

　　3、 Product features:

　　1. Suitable for volumetric flow measurement of conductive fluids with conductivity greater than 5 ц s/cm;

　　2. There are no active or obstructed components inside the measuring tube, and the pressure loss is small;

　　3. Lining and electrodes with different materials have good anti-corrosion performance;

　　4. Not affected by medium, density, viscosity, temperature, pressure, and conductivity;

　　5. Low frequency rectangular wave excitation, less susceptible to interference, stable and reliable;

　　6. The converter has low energy consumption, simple and convenient installation, and users do not need to debug.
