How to choose the right items when you need to buy a gas turbine flow meter

Abstract: When you need to buy a gas turbine flow meter, the information on how to purchase the items correctly is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The gas turbine flowmeter flow sensor is a new type of intelligent instrument that integrates the turbine flow sensor and the display and calculation, which is developed by using advanced ultra-low power single-chip microcomputer technology. . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details on how to correctly purchase items when you need to buy a gas turbine flowmeter. The gas turbine flowmeter flow sensor is a new type of intelligent instrument that integrates the turbine flow sensor and the display and calculation, which is developed by using advanced ultra-low power consumption single-chip microcomputer technology. High performance, no interference from external power supply, anti-lightning, strong overall function, low power consumption, superior performance, small pressure loss, impeller has anti-corrosion function; there are analog standard signals and digital pulse signal output, which is easy to connect with digital systems such as computers It is a relatively advanced and ideal flow meter when used together. 1. Accuracy level: Generally speaking, the selection of turbine flowmeter is mainly based on its high accuracy, but the higher the accuracy of the flowmeter, the more sensitive it is to changes in the field conditions of use. Therefore, the choice of meter accuracy should be Caution, should be considered from an economic point of view. For the trade settlement instruments of large-diameter gas pipelines, it is cost-effective to invest more in the instruments, and for occasions where the transportation volume is not large, the medium-precision level can be selected. 2. Flow range: the same as above 3. Gas density: On gas turbine flowmeters, the influence of fluid physical properties is mainly gas density, which has a greater impact on meter coefficients, mainly in low flow areas. If the gas density changes frequently, corrective measures should be taken to the flow coefficient of the flowmeter. 4. Pressure loss: try to choose a turbine flowmeter with a small pressure loss. Because the pressure loss of the fluid passing through the turbine flowmeter is smaller, the energy consumed by the fluid from the input to the output pipeline will be less, that is, the total power required will be reduced, which can greatly save energy, reduce transportation costs, and improve utilization. . Some people have done tests, and the main component that affects the pressure loss is the front deflector of the turbine flowmeter. Compared with the front deflector of the semi-ellipsoid, the pressure loss of the former turbine can be greatly reduced. 5. Structural type: (1) The reverse thrust turbine flowmeter should be selected for the internal structure. Because the reverse thrust structure can keep the impeller in a floating state within a certain flow range, there is no contact point in the axial direction, and there is no end face friction and wear, which can prolong the service life of the bearing. (2) According to the pipeline connection method, the flowmeter has two types of horizontal and vertical installation. The horizontal installation and pipeline connection methods include flange connection, threaded connection and clamp connection. Flange connections are used for medium diameters; threaded connections are used for small diameter and high-pressure pipelines; clip-on connections are only suitable for low and small diameters; vertical installations only have threaded connections. (3) Selection according to environmental conditions, considering the influence of temperature and humidity. Natural gas metering should choose intrinsically safe explosion-proof turbine flowmeter. 6. Bearings: The bearings of turbine flowmeters are generally made of three types of materials: tungsten carbide, polytetrafluoroethylene, and carbon graphite. Natural gas measuring instrument bearings should be made of tungsten carbide. The above are the main aspects to consider when selecting a model. Since there are many types and specifications of turbine flowmeters, especially the quality of products of different manufacturers is different, when selecting models, you should try to collect relevant technical standards and other information of manufacturers and products, and then make a decision after repeated investigation and comparison. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
