Intrinsically safe mining vortex street flowmeter

The mining vortex flowmeter is measured based on the Karman vortex principle. It can be used to measure the flow rate of various mining media, such as air, carbon dioxide, oxygen, nitrogen, coal gas, natural gas, biogas and other gases. technical parameter ① Measurement accuracy: The measurement accuracy for liquids can generally reach level 1, while the measurement accuracy for gases and vapors is generally level 1.5. Some high-precision products can be ordered through agreements to achieve higher accuracy. ② Repeatability: usually ± 0.3%, ± 0.5%, etc. ③ Caliber specifications: DN15 to DN1500, capable of meeting the flow measurement needs of different mining pipelines. ④ Environmental temperature: -40 ℃ to 55 ℃. ⑤ Power supply: Common options include 24VDC, 12VDC, 3.6VDC, 220VAC, etc. ⑥ Current signal: For example, a 4-20mA current signal can be easily connected to other control devices, instruments, etc. to achieve remote transmission and centralized control of the s…
