Installation requirements: Install on horizontal or vertical pipelines, avoiding areas with severe vibrations, strong magnetic fields, or high-temperature sources. Ensure sufficient straight pipe sections upstream (minimum 10 times pipe diameter) and downstream (minimum 5 times pipe diameter) to maintain stable fluid flow and measurement accuracy. Connection methods: Use flange or threaded connections based on pipeline dimensions and pressure ratings. Ensure proper sealing during installation to prevent fluid leakage.

**Directional Requirements:** The flow meter must be marked with an arrow indicating the direction of fluid flow. During installation, ensure the fluid flow direction aligns with the arrow; otherwise, measurement accuracy may be compromised or the instrument's electrical connections may be damaged. Follow the instrument's manual for electrical wiring, ensuring proper and secure connections to prevent signal transmission failures caused by poor contact.  **Precautions:**  - **Media Filtration:** Install a filter upstream of the flow meter to remove impurities and particles from the fluid, preventing damage to measurement components and affecting accuracy and service life.  - **Start/Stop Procedures:** When starting the system, slowly open the valve to avoid sudden changes in fluid velocity that could shock the instrument. When stopping the system, first close the valve downstream of the flow meter before shutting off the upstream valve.  - **Regular Calibration:** To maintain measurement accuracy, calibrate the flow meter periodically (typically every 1–2 years), with specific intervals determined by operational requirements. Perform regular inspections of the instrument's appearance, connections, and output signals, addressing any abnormalities promptly. Apply lubricant to lubricated components as specified in the manual. Avoid idling the instrument during measurement to prevent internal component damage.  - **Environmental Protection:** In harsh environments, implement protective measures such as protective covers or insulation layers to safeguard the instrument from environmental factors.
