1. Types and selection of gas flow meters
Types and selection of gas flow meters include vortex street type, target type, V-cone type, Velbar type, and orifice plate type.
1、 Vortex flowmeter is generally used for flow measurement of industrial pipeline media fluids, such as liquids, vapors, gases, and other media. It has the characteristics of high accuracy, low pressure loss, and large range. When measuring the volumetric flow rate under working conditions, it is almost not affected by parameters such as fluid density/pressure, viscosity, temperature, etc. This type of non movable mechanical component has high reliability, low maintenance, and can sell virtual beams with stable instrument parameters for a long time. This type of instrument uses piezoelectric stress sensors, so it has high reliability and can generally operate within a temperature range of -20 ℃ to+250 ℃. This type of flowmeter usually has analog standard signals as well as digital pulse signal outputs, making it easy to be used in conjunction with digital systems such as computers. It is currently an advanced and ideal flow meter on the market.
2、 Target flow meters have been used in industrial flow measurement since the 1960s, generally for measuring the flow of gases, liquids, and vapors. They are mainly used to solve the flow measurement of high viscosity, low Reynolds number fluids. This type of flowmeter has gone through two major stages of development: pneumatic meters and electric meters. Both SST and SBL intelligent target flow meters are based on the measurement principle of the original strain gauge target flow meter, using chip level II capacitive force sensors as measurement and sensitive transmission components, an

3. V-cone flowmeter is widely used in the fields of petrochemicals, natural gas, etc. due to its simple structure, strong universality, low price, firmness, and easy replication.
. The V-cone flowmeter compensates for the shortcomings of standard orifice plates, Venturi tubes, nozzles and other throttling devices, such as easy wear, high pressure loss, high on-site installation conditions, long required straight pipe sections, and small range (range ratio). Capable of accurately measuring the flow rate of various fluids over a wide range of Reynolds numbers. Compared with ordinary differential pressure flow meters, the STV series V-cone flowmeter has the characteristics of stable long-term accuracy, good repeatability, high accuracy, limited installation conditions, wear resistance, suitability for dirty media, low pressure loss, wide measurement range, and long service life. This type of flowmeter is suitable for many fields, generally suitable for measuring coal gas, petroleum gas, water, oil, various liquids, steam, air, oil residue, natural gas, organic gases, etc.4、 The Weiliba type Weiliba flowmeter is mainly suitable for high-precision flow measurement of gases, liquids, and vapors. The Weiliba type is a differential pressure, rate averaging flow sensor that measures flow through the differential pressure generated by the sensor in the fluid. Zhongyun Weiliba can reflect the true flow velocity of fluids with an accuracy of ± 1.0% and a repeatability of ± 0.1%. One outstanding advantage of the Velbar is its ability to output a very stable and pulsation free differential pressure
