1. What meter should be used for industrial gas with a flow rate of over 1000 cubic meters per hour?
DN150 vortex gas flowmeter, DN150 gas turbine flowmeter, or DN150 gas Roots flowmeter can be used for industrial gas with a flow rate of over 1000 cubic meters per hour. Here are some brief explanations about these three types of flow meters: DN150 spiral vortex gas flow meter: suitable for measuring high flow gas media such as industrial gas. The Daling Mausoleum has the characteristics of high measurement accuracy, good stability, and low pressure loss. When selecting, parameters such as the nominal diameter, working pressure, and working temperature of the pipeline should be considered. DN150 gas turbine flowmeter: suitable for measuring gas media with high flow rate and large flow rate. It has the advantages of wide measurement range, fast response speed, and high accuracy. When selecting, it is necessary to pay attention to factors such as the characteristics of the measuring medium, flow range, and installation method. DN150 gas Roots flowmeter: suitable for measuring gas media with high flow rate and low pressure loss. It has the characteristics of simple structure, easy maintenance, and stable measurement. When selecting, it is necessary to determine based on the properties of the measuring medium, the nominal diameter of the pipeline, and environmental conditions. Key content: In the selection process, in addition to considering the applicable range and characteristics of the flowmeter, it is also necessary to accurately determine the characteristics of the measuring medium, the nominal diameter of the pipeline, the working pressure, the working temperature, the flow range, the installation method, and
2. How to choose a gas vortex flowmeter?
The selection of vortex flowmeter mainly confirms the following parameter requirements:
1. Measurement medium for cavity bending.
. Turbine flowmeter is a type of velocity flowmeter that utilizes the principle of Karman vortex street. When the medium passes through the vortex generator, small vortices are formed behind it. The number of vortices can be converted into the flow velocity of the medium, which in turn can be converted into the flow rate of the medium. Its principle determines the type of measuring medium, which can be liquid, gas, or vapor. At present, the vast majority of industrial applications, such as nitrogen, compressed air, steam, thermal oil, etc., mostly use vortex flowmeters for measurement.2、 Pipeline diameter. Vortex flow meters can be installed in different ways, including pipeline installation and plug-in installation. For pipeline type flow meters, the diameter of the pipeline is the same as most other flow meters. The smaller one is DN15, while the larger one can reach DN300. If a larger caliber is required, plug-in installation can be chosen. The conventional caliber range can reach up to DN2000, and calibers above DN2000 will be supplied according to the agreement.
3、 Measurement accuracy. The accuracy of vortex flowmeter also has several levels, and it is classified according to the measuring medium. The pipeline type vortex flowmeter can achieve a measurement accuracy of 1.0 level for liquids and 1.5 level for gases. If it is an inser
