How to troubleshoot for gas turbine flowmeter measurement？
2021-06-02
In use, some users may encounter inaccurate measurement or unstable measurement results of gas turbine flowmeters, do not worry, such as this problem you can first step by step to eliminate the following reasons:
1. The accuracy of the gas turbine is generally 1%-1.5%, that is to say, its error is generally about 1%-1.5%, and the error is OK as long as it is within this range.
2.whether the selection is correct, the flow range measured by different caliber instruments is different, once it exceeds this range, the measurement will not be allowed.
3. Check whether the installation is correct, whether the straight pipe section is left enough, whether it is too close to the valve or the bend position, check whether there is a problem with the line, and whether there is any interference such as motor, frequency converter, and strong current nearby, which will affect the measurement accuracy of the gas turbine flowmeter.
4.whether there is water in the gas, whether there is corrosion, whether there is oil in the gas, whether the pipeline is cleaned, there is no impurities in the pipeline, there is water or oil in the gas, it is necessary to install a gas and liquid separator before the instrument, and there are impurities in the gas need to install a filter before the instrument.
5. Whether the instrument is worn, because the impeller is running for a long time, it will produce some wear, and the accuracy will decline after wear, so it is necessary to regularly add lubricating oil to the instrument for maintenance. Kailong's gas turbine has a built-in oil cup, which is convenient for lubrication, saves time and cost, and improves the life and accuracy of the instrument.
6.check whether the sensor K coefficient and instrument parameters are set correctly, the instrument coefficient is set by the factory, if the coefficient is wrong, please contact the manufacturer.
