　　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 the gas turbine flowmeter, and an oil filter should be installed in places with dirty gas. It is strictly prohibited to directly connect the filter and flowmeter.

　　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.
