　　5. Built in pressure and temperature sensors, high safety performance, compact structure, and beautiful appearance;

　　6. The instrument has explosion-proof and protective functions, with explosion-proof markings of Exd Ⅱ BT6 and Exia Ⅱ CT6, and a protection level of IP65;

　　7. The system operates with low power consumption, and a 3.2V10AH lithium battery can be used continuously for more than 3 years;

　　8. The instrument coefficient and cumulative flow value will not be lost for ten years after power failure.

　　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.

　　6. During pipeline pressure testing, attention should be paid to the pressure measurement range of the pressure sensor equipped with the intelligent vortex flowmeter to avoid damage to the pressure sensor due to overpressure.
