Description :

　　LWQ-50 Intelligent Gas Turbine Flow Meter

　　This product is suitable for measuring natural gas, dry coal gas, compressed air, etc. It is widely used in the measurement and control systems of petroleum, chemical, metallurgical, scientific research and other fields.

　　1、 Technical parameters:

　　1. Tested media: natural gas, coal to gas, air, etc

　　2. Environmental temperature: -20 ℃ to+50 ℃

　　3. Medium temperature: -20 ℃ to+80 ℃

　　4. Explosion proof rating: Exib Ⅱ BT4, Exd Ⅱ BT6

　　5. Output signal: Voltage pulse, 4-20mA two-wire system

　　6. Communication interface: RS-485 communication interface is selected.

　　7. Power supply: Sensor: 12V DC (pulse output) Transmitter: 24VD (current output) 3.0V lithium battery (on-site display)

　　2、 Main functional features

　　Intelligent integrated design, Chinese character dot matrix display and multiple output functions:

　　FH-LWQ: without pressure or temperature sensors, displaying volumetric flow rate under operating conditions; Non real time temperature and pressure compensation can be achieved by manually setting pressure and temperature values. Display standard flow rate.

　　FH-LWQZ type: integrates flow rate, temperature, pressure sensors, and intelligent flow integrator to achieve temperature/compaction compensation of flow rate and display standard volumetric flow rate.

　　Equipped with software spectrum analysis function, it improves the anti-interference and seismic resistance of the instrument;

　　Use magnetic resistance sensors. Low starting flow rate, small pressure loss, high accuracy, and good repeatability;

　　Adopting dual power supply, with a built-in 3.6VDC lithium battery for power supply. When powered by an external 24VDC, the internal power supply automatically switches;

　　Power outage protection function; Adopting E2PROM technology, internal parameter storage.

　　The use of imported fully sealed and isolated self-lubricating micro torque bearings greatly improves the service life of the instrument;

　　Low installation requirements: The front straight pipe section should be ≥ 3D, and the rear straight pipe section should be ≥ 1D to ensure the measurement accuracy of the instrument;

　　Explosion proof structural design, suitable for measuring explosive gases;

　　Easy to install and operate, stable and reliable to use.

　　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.
