Cov khoom siv Flow Meter

Kev xaiv cov khoom siv rau cov ntsuas ntws nyob ntawm qhov ntsuas nruab nrab (xws li corrosiveness, huv si, viscosity), kev ua haujlwm (xws li kub, siab), thiab qhov yuav tsum tau muaj tseeb.

Common Flow Meter Material Pawg:

Stainless hlau (xws li 304, 316L)
Dav siv nyob rau hauv hlau rotor flow meters, electromagnetic flow meter vaj tse, turbine flow meters, thiab lwm yam., haum rau me me corrosive media.

Polytetrafluoroethylene (PTFE)
Muaj tshuaj lom neeg ruaj khov zoo heev, tiv taus cov kua qaub muaj zog, muaj zog alkalis, thiab cov kuab tshuaj organic, feem ntau siv los ua cov hlua rau cov khoom siv hluav taws xob electromagnetic flowmeter, haum rau cov xov xwm corrosive xws li concentrated sulfuric acid thiab aqua regia.

Hastelloy (xws li HB, HC)
Siv rau cov khoom siv hluav taws xob, tiv taus oxidizing acids (xws li nitric acid) thiab txo cov kua qaub (xws li hydrochloric acid), haum rau cov tshuaj corrosive heev.

Tantalum (Ta) thiab Platinum -Iridium Alloy
Tantalum tiv taus yuav luag txhua yam tshuaj lom neeg (tshwj tsis yog hydrofluoric acid thiab fuming sulfuric acid); platinum-iridium alloys yog tsim rau ze li ntawm tag nrho cov corrosive kua thiab ua hauj lwm raws li siab -cov ntaub ntawv electrode precision.

PVDF, Vectra
Siv rau wetted qhov chaw ntawm siab -precision turbine flow meters, corrosion-resistant thiab haum rau cov dej huv.

Fluoroplastic Linings (xws li F46, PFA)
Siv nyob rau hauv electromagnetic flow meters los txhim kho qhov kub thiab txias tsis kam, compensating rau cov kev txwv ntawm PTFE nyob rau hauv tsis zoo siab los yog kub kub.

Cov khoom siv roj hmab (xws li Neoprene, Polyurethane)
Siv rau hauv hnav- daim ntaub ntawv tiv taus, xws li ntsuas dej phwj uas muaj slurry lossis ntxhia slurry.
