Accuracy is the criterion for judging the quality of a gas flow meter

Accuracy is the standard for judging the quality of the instrument, but if the product quality is excellent, but the result is inaccurate, at this time, it is necessary to think carefully whether it has been affected during the test! First of all, we must choose a qualified manufacturer to purchase, (hereinafter referred to as“Seven Star Flowmeter”), is a manufacturer specializing in gas flow measurement and control. Its predecessor was a manufacturer of domestic mass flow controllers. In 1979, the mass flow controller D07-1/ZM was developed. Since then, D07 series products have been widely used in various industries and research fields across the country by virtue of advanced technology, and have had a greater influence among users. From the 1980s to the 1990s, Qixing Flowmeter, as a professional manufacturer of flow measurement and control products, has been leading the development trend of the domestic flowmeter field: undertaking national“six five”Plan to tackle the key project of rapid mass flow controller, successfully developed a mass flow calibration platform, and drafted and compiled domestic regulations on gas mass flow controllers.“Ministry of Electronics Industry Standards”etc. Error 1: Unreasonable pipeline design Gas flowmeter is a commonly used gas measuring instrument, mainly for measuring gas, air, nitrogen, hydrogen, etc. Two parallel pipelines, when the main network uses gas, the manual valve of the branch network is closed. The measurement of the gas flowmeter is normal. When the sub-pipe network is also using gas, the manual valve is opened. Since the gas in the main pipeline is partly diverted by the sub-pipe, the air pressure in the main pipeline will drop, so it is necessary to install a check valve in front of the No. 1 flowmeter. . Error 2: No distinction between high pressure and low pressure. High pressure metering and low pressure gas. If the meter is installed on the high-pressure pipeline, and the pressure is adjusted by the pressure regulator, the user uses gas on the low-pressure pipeline. When the gas consumption of the low-pressure pipeline is not large, according to the gas state equation, when the temperature is similar, The small flow rate of the low-pressure pipeline will be even smaller when calculated back to the flow rate of the high-pressure pipeline, which may not reach the initial flow rate of the flowmeter. The flow meter does not count. Error 3: Improper installation Correct installation of the gas flowmeter will help improve measurement accuracy and prolong service life. When the flowmeter is installed on the pipeline, it should be ensured that the threaded hole on the flowmeter body is aligned with the screw hole of the pipe flange to ensure the parallelism of the flange, avoid the flowmeter from being subjected to other external forces, and prevent the meter body from being deformed by force. The flow meter is stuck. When opening the flowmeter, the front valve should be opened first, and then the rear valve should be opened slowly, so that the gas flowmeter can be started under pressure, so as to avoid the flowmeter rotor being impacted and deformed by the gas due to the air hammer effect, causing the flowmeter to be stuck.
