1. User Manual for Shanghai Ziyi Jiuyi Intelligent LDCK Electromagnetic Flow Meter: [3]
The core content of the user manual for Shanghai Ziyi Jiuyi Intelligent LDCK Electromagnetic Flow Meter is as follows:
1. Product Overview: The intelligent LDCK electromagnetic flow meter is a high-precision flow measurement instrument designed based on Faradays law of electromagnetic induction, suitable for measuring the volume flow of conductive liquids (such as water, acid-base solutions, slurries, etc.). Its characteristics include: high-precision cavity: measurement error ≤ ± 0.5%, strong stability. Wide range ratio: The range ratio can reach 1:150, suitable for different flow scenarios. Strong anti-interference ability: using digital signal processing technology to effectively suppress noise interference. Multiple output modes: Supports pulse, 4-20mA current, RS485 communication, and other outputs for easy system integration.
2. Installation requirements: Installation location selection: Avoid strong magnetic fields, strong vibration environments, and stay away from interference sources such as pumps and valves.
. Ensure that the pipeline is filled with liquid to prevent empty or half pipe conditions. Horizontal or vertical installation is acceptable, but when installing vertically, it is necessary to ensure that the fluid direction is from bottom to top. Pipeline preparation: Before installation, the inner wall of the pipeline needs to be cleaned to avoid impurities affecting the measurement. The diameter of the pipeline should be consistent with the diameter of the flow meter. If it is necessary to reduce or expand the diameter, a gradient pipe should be used. Grounding requirements: The flowmeter ca_600x400.jpg)
III. Operation Method Parameter Setting: Set parameters such as flow unit, range, and zero correction through buttons or upper computer software.
. Zero calibration is required for the first use (to ensure that the pipeline is operated without fluid). Daily operation: After powering on, observe the instrument self-test process and confirm that there are no alarm messages. Regularly check the stability of the output signal and record traffic data. Maintenance: Check the electrode contamination every 6 months and clean it if necessary. Verify the instrument accuracy once a year to ensure measurement accuracy.Fourth, common faults and solutions: large fluctuations in flow display: reasons: pipeline vibration, fluid pulsation, electrode contamination.
. Treatment: Strengthen the pipeline, install buffer devices, and clean the electrodes. No flow output: Reason: power failure, signal line open circuit, sensor damage. Solution: Check the power supply, replace the signal line, and contact after-sales to replace the sensor. Large measurement deviation: Reasons: incorrect parameter settings, low fluid conductivity, empty tube. Processing: recalibrate parameters, confirm fluid conductivity ≥ 5 μ S/cm, check pipeline filling status. Communication abnormality: Reason: RS485 interface damage, communication protocol mismatch. Handling: Check interface connections and confirm protocol settings (such as Modbus RTU).Fifth, precautions: It is strictly prohibited to operate air traffic control: air traffic control filming can cause electrode scali
