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 operating conditions | Requirements for pressurized operating conditions | | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The vortex flowmeter is a precision instrument for measuring fluid flow based on the Karman vortex principle. It mainly consists of sensors, converters, measuring tubes, and auxiliary components. Its structural design embodies the engineering philosophy of "simplicity contains precision" and is continuously optimized with the development of technology.

First, the core structure of the sensor vortex generator: a

non streamlined cylindrical object inserted into the fluid pipeline and imitated, whose geometric shape (such as triangular columns, cylinders) directly affects the stability of vortex separation.

. When fluid flows through, two columns of staggered vortices are generated on both sides of the cylinder. The separation frequency of vortices is proportional to the flow velocity and inversely proportional to the width of the cylinder. This is the core application of the Karman vortex street principle. Detecting chaotic fiber components: including detection probes and detection amplifiers, converting physical signals into electrical signals by sensing pressure or frequency changes generated by vortex separation. The detection probe and vortex generator adopt a separate structure, effectively avoiding the problem of pressure hole blockage and improving reliability. Connecting rod: Connect the detection object and the detection amplifier to ensure the stability of signal transmission. The sensor adopts gas shielded self melting welding technology inside, which is corrosion-resistant, durable and sturdy. Figure: Schematic diagram of sensor structure, showing the layout of vortex generator and detection element. The converter converts the electrical signal output by the sensor into a standard flow signal (such as 4-20mA current or pulse signal), and has temperature and pressure compensation functions to adapt to different working conditions. Contemporary converters integrate microprocessors, enabling digital processing, self diagnosis, and remote communication. The channel through which the fluid flows in the measuring tube is usually made of all stainless steel material to ensure corrosion resistance and mechanical strength.
