Fenghui Instrument DN25 Gas Turbine Flow Meter

Description :

　　Fenghui Instrument DN25 Gas Turbine Flow Meter

　　This product has the advantages of high precision, good repeatability, simple structure, wide measurement range, small volume, light weight, low pressure loss, and easy maintenance.

　　1、 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.

　　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.

　　7. Explosion proof signs: Exib Ⅱ BT4, Exd Ⅱ BT6;

　　3、 Installation method:

　　1. Before installing the gas turbine 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 gas turbine flowmeter can be installed and used.

　　3. When installing a gas turbine 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.
