　　2、 Characteristics

　　1. The impeller has anti-corrosion function and can measure the flow rate of corrosive gases.

　　2. Adopting low-power single-chip microcomputer technology, the whole machine has powerful functions, low power consumption, and reliable performance.

　　3. The intelligent flow display header with non-linear accuracy compensation function has a correction formula accuracy better than ± 0.02%.

　　4. The instrument coefficient can be set online through buttons and displayed on an LCD screen, which is intuitive, clear, and highly reliable.

　　5. Using EEPROM for accumulated flow and instrument coefficient power failure protection, with a protection time greater than 10 years.

　　6. Using high-performance MCU central processing unit to complete data acquisition, processing, display and output, and accumulate instantaneous traffic.

　　7. Convenient human-machine interface implementation with screen display, data transmission in standard 485 format.

　　3. Installation

　　1. Stop valves should be added before and after installation.

　　2. There should be no protrusions connected to the flange joint inside the pipeline.

　　3. When installing a gas turbine flowmeter, it is strictly prohibited to directly weld at its inlet and outlet flanges to avoid burning out the internal parts of the flowmeter.

　　4. The flowmeter should be installed in a location that is easy to maintain, free from strong electromagnetic field interference, mechanical vibration, and thermal radiation effects.

　　5. Not suitable for installation in situations where flow is frequently interrupted and there is strong pulsating flow or pressure pulsation;

　　6. When installing the flowmeter outdoors, there should be a cover on the upper part to prevent rainwater from entering and direct sunlight from affecting the service life of the flowmeter.

　　7. The flowmeter can be installed horizontally or vertically, and the direction of fluid flow should be consistent with the direction marked on the shell. When installing in a vertical pipeline, the flow direction must be upward and downward. A straight pipe section of not less than 10Dn should be ensured upstream of the flowmeter, and a straight pipe section of not less than 5Dn should be ensured behind the meter.
