Jiangsu LDG electromagnetic flowmeter manufacturer

Description :

　　Jiangsu LDG electromagnetic flowmeter manufacturer

　　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:

　　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 ℃;

　　2、 Characteristics:

　　1. Measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity;

　　2. There are no obstructing flow components or pressure loss inside the measuring tube, and the requirements for straight pipe sections are relatively low;

　　3. Reasonably selecting sensor lining and electrode materials, which have good corrosion resistance and wear resistance;

　　4. The converter adopts a novel excitation method, with low power consumption, stable zero point, and high accuracy. The flow range can reach 150:1;

　　5. The converter can be integrated or separated from the sensor;

　　6. The converter adopts a 16 bit high-performance microprocessor, 2x16 LCD display, convenient parameter setting, and reliable programming.

　　3、 Installation:

　　1. The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements; In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level can be chosen, such as 1.5, 2.5, or even 4.0,.

　　2. When measuring medium flow rate, instrument range, and caliber, the full flow rate of the flowmeter can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.

　　3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.

　　4. There should be ample space around the flowmeter for easy detection and maintenance.
