1. Flow range of steam vortex flowmeter

The flow range of steam vortex flowmeter varies depending on its model and diameter. The diameter (DN) represents the diameter of the pipeline, while the flow range represents the flow value that the flowmeter can measure. The model OW-LU-25 is suitable for DN25 pipelines, with a flow range of liquid 1-10 m ³/h and gas 25-60 m ³/h. For steam flow, it is recommended to refer to the instruction manual. For large pipelines above DN300, it is recommended to use an inserted vortex flowmeter. The model OW-LU-32 is suitable for DN32 pipelines, with a flow range of 1.5-18 m ³/h for liquids and 15-150 m ³/h for gases. The model OW-LU-40 is suitable for DN40 pipelines, with a flow range of 2.2-27 m ³/h for liquids and 22.6-150 m ³/h for gases. The model OW-LU-50 is suitable for DN50 pipelines, with a flow range of liquid 4~55 m ³/h and gas 35~350 m ³/h. The model OW-LU-80 is suitable for DN80 pipelines, with a flow range of 9-135 m ³/h for liquid differential and 90-900 m ³/h for gas. The model OW-LU-100 is suitable for DN100 pipelines, with a flow range of 14-200 m ³/h for liquids and 140-1400 m ³/h for gases. The model OW-LU-150 is suitable for DN150 pipelines, with a flow range of 32-480 m ³/h for liquids and 300-3000 m ³/h for gases. The model OW-LU-200 is suitable for DN200 pipelines, with a flow range of 56~800 m ³/h for liquids and 550~5500 m ³/h for gases. Based on the above information, you can choose a suitable steam vortex flowmeter according to your pipeline diameter and understand the flow range it can measure. The steam vortex flowmeter is mainly used for measuring the flow rate of steam medium fluid in industrial pipelines. The characteristics of steam vortex flowme

3. How to choose a vortex flowmeter under pressure conditions The core parameters for selecting 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) •
