Natural gas LWQ series gas turbine flowmeter

Description :

　　Natural gas LWQ series gas turbine flowmeter

　　This product is a speed type instrument. It has the advantages of high accuracy, good repeatability, simple structure, wide measurement range, small volume, light weight, low pressure loss, and easy maintenance. It can be widely applied in industries such as petroleum, chemical, metallurgical, and urban gas pipeline networks. Especially in urban gas metering, transmission and distribution network metering, and gas pressure regulating station metering, it has been widely used.

　　1、 Characteristics:

　　1. High accuracy: The full range is generally 1% -2.0%, and the high-precision type is 0.5% -1.0%; It belongs to a high-precision category.

　　2. Good repeatability: generally up to 0.05% to 0.2%. Due to its good repeatability, it can achieve extremely high accuracy through regular calibration or online calibration, making it one of the preferred flow meters in trade settlement.

　　3. Wide range: Generally, the medium and large caliber can reach 20:1 or more, while the small caliber is 10:1, and the starting flow rate is also relatively low.

　　4. The pressure loss is relatively small: generally between 0.1 and 2.5 kPa under normal pressure.

　　5. Compact structure, lightweight volume, easy installation and use, and high circulation capacity.

　　6. Multiple display modes can be used, including only mechanical counters or ordinary flow integrators. Temperature and pressure compensators can also be added to the mechanical counters, or only temperature and pressure compensators can be used. It can also be powered by lithium batteries for a long time, making it easy to use.

　　7. Due to the general use of pulse frequency signal output, it is suitable for total measurement and connection with computers, with no zero drift and strong anti-interference ability. If high-frequency signal output is used, a very high frequency signal (3-4kHz) can be obtained with strong signal resolution.

　　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.
