　　2、 Characteristics:

　　Wide measurement range, lower limit flow rate below 0.5m/s, low pressure loss, and strong impact resistance of the impeller.

　　It has high resistance to electromagnetic interference and vibration, and adopts fully sealed isolation protection for self-lubricating bearings, with reliable performance and long working life.

　　Adopting advanced ultra-low power single-chip microcomputer technology, the whole machine has strong functions, low power consumption, and superior performance. Intelligent flow display with non-linear accuracy compensation function. Correction formula

　　The accuracy is better than ± 0.02%.

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

　　Using EEPROM for power down protection of accumulated flow and instrument coefficient. The protection period is greater than 10 years.

　　Pressure compensation can be performed under stable pressure conditions of the measured gas.

　　3、 Installation:

　　1. Before installing the flowmeter, the pipeline must be blown clean to prevent residual iron filings from affecting the normal operation of the flowmeter.

　　2. Before installation, if the turbine can rotate flexibly without irregular noise when blown by a small airflow, and the counting rotation is normal without any interruption or jamming, then the flowmeter can be installed and used.

　　3. When installing the flowmeter, a sealing gasket should be added between the flange and the pipeline flange.

　　4. A filter should be installed before, and an oil filter should be installed in places with dirty air. It is strictly prohibited to directly connect the filter to the flow meter.

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

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

　　7. 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.

　　8. 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.

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

　　10. 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.
