　　3、 Attention:

　　1. The directional signs can be installed in vertical, horizontal, or any inclined position.

　　2. When the pipeline is long or close to the vibration source, supports should be installed upstream and downstream of the flowmeter to eliminate the impact of pipeline vibration.

　　3. The installation location of the vortex flowmeter should have sufficient space for inspection and maintenance of the flowmeter, and should meet the environmental requirements of the flowmeter.

　　4. Avoid interference from strong external magnetic fields.

　　5. When installed and used outdoors, there should be a cover to avoid direct sunlight and rainwater erosion, which may affect the service life of the instrument.
