Detailed installation steps for natural gas turbine flowmeters

Thread Content

　　The VNLWQ natural gas flow meter is a product newly developed by our company. Unlike previous natural gas flow meters, the biggest advantage of this new product is its simple and convenient installation. Below, our technical team will provide you with detailed information on the installation requirements for this natural gas turbine flow meter. 　　Installation requirements for natural gas turbine flowmeters: 1. Before installation, the pipeline must be purged to prevent residual debris and iron particles from affecting the proper operation of the flowmeter. 　　2. Before installation, when the turbine is blown with a gentle airflow, it should rotate smoothly without any irregular noises; if the counting of rotations is normal and there is no intermittent sticking, then the flow meter can be installed and used. 　　3. When installing the flow meter, a sealing gasket must be placed between the flange and the pipeline flange. 　　4. A filter should be installed in front of the flow meter; in cases where the fluid is quite dirty, an oil filter should be used. Before placing an order, customers can order both from our company at the same time. It is strictly prohibited to connect the filter directly to the flow meter. 　　5. Shut-off valves should be installed at both the front and back of the flow meter during installation. 　　6. There should be no protrusions at the inner diameter of the pipe at the flange connection. 　　7. When installing the flow meter, it is strictly prohibited to perform welding directly on its inlet and outlet flanges, to avoid damaging the internal components of the flow meter. 　　8. The flow meter should be installed in a location that is easy to maintain, free from strong electromagnetic interference, mechanical vibration, and thermal radiation effects. 　　9. Flowmeters should not be used in situations where flow is frequently interrupted, or where there are strong pulsations in the flow or pressure. 　　10. When the flow meter is installed outdoors, it should be covered at the top to prevent rainwater from seeping in and direct sunlight from affecting its service life. 　　11. The flow meter can be installed horizontally or vertically; the flow direction of the fluid should be consistent with the direction indicated on the housing. There must be a straight pipe section of at least 10Dn upstream of the flow meter, and a straight pipe section of at least 5Dn downstream of it. 　　12. To avoid disrupting the normal flow of the fluid, it is recommended to install a bypass pipeline; the valve of this bypass pipeline must be closed during normal operation. 　　Flow metering is one of the components of metrological science and technology, and it is closely related to the national economy, national defense construction, and scientific research. Doing this job well plays an important role in ensuring product quality, improving production efficiency, and promoting the development of science and technology. Especially in today’s era of energy crises and an increasing degree of automation in industrial production, the significance and role of flow meters in the national economy have become even more evident.
