1. IFM4110 Electromagnetic Flow Meter Installation Manual: [6]
The core content of the IFM4110 Electromagnetic Flow Meter Installation Manual is as follows:
1. Preparation for Environmental Inspection Before Installation: Ensure that the installation location is away from strong magnetic fields, vibration sources, and corrosive cherry blossom gas environments, and avoid direct sunlight or areas with drastic temperature changes. Pipeline requirements: The inner diameter of the pipeline must be consistent with the nominal diameter of the flow meter, with an error not exceeding ± 1%. The installation section of the pipeline should be kept horizontal or vertical, with an inclination angle not exceeding 5 °. The inner wall of the pipeline should be smooth and free of defects such as scaling and burrs.
2. Installation steps: Flange connection: Align the flowmeter flange with the pipeline flange, insert the bolts and tighten them evenly. The torque value should meet the requirements of Table 1 (refer to page 3 of the instruction manual).
. Check the flange clearance after connection to ensure uniformity and no deviation. Grounding treatment: Use copper wires with a cross-sectional area of ≥ 16mm ² to connect the flowmeter grounding terminal to the pipeline grounding grid. The grounding resistance should be less than 10 Ω to avoid sharing the ground wire with power cables. Sensor installation: The sensor direction should be consistent with the fluid flow direction, with the arrow pointing downstream. After installation, check the coaxiality between the sensor and the pipeline, with an error of ≤ 0.5mm.3. Electrical connection power wiring: Use shielded cables to connect the power terminals, with
4. Debugging and Calibration Zero Point Calibration: Ensure that the pipeline is filled with medium and there is no flow, and enter the calibration menu through the operation panel. The zero offset should be less than ± 0.5% FS. Range setting: Set the range according to the actual flow range, and the upper limit value should be greater than 20% of the maximum expected flow. Linearity verification is required after range adjustment.
5. Common fault handling: No flow display: Check if the power supply is normal and if the signal line is disconnected.
. Confirm whether there is medium flow inside the pipeline. Large traffic fluctuations: Check if the grounding is good and if there are any interference sources nearby. Confirm whether the medium contains bubbles or solid particles. Caution: It is strictly prohibited to strike the sensor during installation to avoid damaging the electrode. Regularly check the grounding resistance and perform zero calibration every 6 months. When the temperature change of the medium exceeds 50 ℃, the range needs to be recalibrated.2.
