How to install a natural gas flow meter to ensure its measurement accuracy
2021-04-29
Natural gas flowmeter is a very high precision instrument with high reliability and long life. At present, the flowmeter is mainly composed of two parts, one is the sensor directly in contact with the transport medium in the pipeline and the upper end of the signal converter. For consumers, consumers buy natural gas flow meters, before using such a meter, should first connect the flow meter with the pipeline.
At present, the flow meter industry, flow meter mode varies by industry. First of all, the use of flange connection, the use of flange connection is more traditional, the two ends of the natural gas flow meter can be connected, when the flange is connected to the pipeline, the fixed two ends of the flange and the bolt used in the pipeline can be. This installation method can be basically one-way installation, but because the sensor volume limit of the connected flowmeter is small, it is only suitable for small volume pipelines. Another way to install a natural gas flow meter is to install a connection. This connection method is more advanced, and the meter without a flange connection hole is now also connected in this connection method.
This connection seems relatively simple at the moment. The characteristics of natural gas flowmeter is that the transport medium loss is small, the measurement range is wide, the accuracy is particularly high, and the measurement of air flow in the measurement process is almost not affected by environmental parameters such as density pressure and temperature. Therefore, at present, many industries and fields are using this flow meter, because the reliability of this flow meter is very reliable, there are not too many mobile mechanical parts inside the flow meter, the workload of late maintenance is less, and you can maintain a long-term stable working state. Only before the use of air metering, it is necessary to ensure that the flow meter is correctly installed on the pipeline, so as to avoid unnecessary measurement errors in the later measurement and use process.
