1. How to choose a vortex flowmeter under pressure conditions

The core parameters for choosing a vortex flowmeter under pressure conditions are that the pressure resistance level must be ≥ 1.5 times the working pressure, and the 316L stainless steel shell is preferred when the medium temperature is ≤ 350 ℃. 1. Selection of pressure resistance parameters - nominal pressure resistance level ≥ 1.6 times the maximum working pressure of the system (GB/T12264-2022 standard) - pressure resistance range of conventional industrial vortex street flow meters: PN10~PN420 (1~42MPa) - ultra-high pressure models need to be specially customized, up to PN630 (63MPa). 2. Structural material requirements • Shell material: carbon steel (≤ 2.5MPa), 304 stainless steel (≤ 4.0MPa), 316L stainless steel (≥ 4.0MPa or corrosive medium) • Vortex rough stroke generator: must be made of solid processed hard alloy (such as WC Co) • Sealing form: metal wound gasket (≤ 350 ℃) or graphite gasket (>350 ℃). 3 Key performance indicators | Parameters | Requirements for conventional working conditions | Requirements for pressurized working conditions | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

1. Vortex flowmeter models cover different media and flow scenarios, including FS series for industrial gas measurement and micro vortex flowmeter for small flow detection

2 Ultrasonic flow meters are suitable for pipeline flow detection, with a diameter range from DN20 to DN6000mm, which can meet the measurement needs of liquids and gases. There is also a wireless ultrasonic flow meter model that is more conve

5、DN40、DN50、DN80、DN100（ Unit: mm) There are a total of 8 specifications for physical flow meters. Taking EXAIRs 9090 model as an example, it is compatible with 1/2 "to 8" Schedule 40 iron pipes and 25mm to 101mm aluminum pipes, and can support up to 4 "copper pipe air flow measurement. • Vortex/Swirl Vortex Flowmeters: including the conventional DN20-DN200 Swirl Vortex Flowmeters from Astra Instruments and the LUGB series from Chongqing Chuanyi. Ultrasonic flow meters: such as Emerson FLUXUS G721 CA clamp type, Astra ATLS clamp type, and other models.

3. What are the models of EH steam flow meters with pressure compensation

The mainstream models of E+H steam flow meters with pressure compensation are as follows

1. Vortex type steam flow meter series • 7F2C series: including 7F2C2

5, 7F2C40, 7F2C50, and 7F2C254050 models, belong to vortex type steam flow meters that integrate temperature and pressure compensation, are easy to install, and have stable measurement accuracy.
