When we choose flow meter, if measurement technique is affirmatory, and be below the premise that appearance function asks to master basically, the installation of the character that tightening what need a consideration then is a fluid and appearance asks, the category that the element that in fluid character the respect needs to consider has a fluid, temperature, pressure, density, viscosity and lubricity, caustic wait with abrasion, wholesome requirement, the installation direction that installs a respect to need the element of the consideration to have appearance, flow direction, fluctuation swims position of conduit state, valve, defend sexual fittings, pulsatile stream influence, oscillatory, electric interference and safeguard a space to wait. Of course, want to choose flow meter correctly, besides master character of appearance function, fluid and installation requirement outside 3 big factors, still need to consider other factor, for instance spot environment element is mixed economic element. Have integration analysis only the element of each respect, ability has chosen the flow meter that we need, make flow meter produces due effect.
Respect element analyses 1 fluid character
After primary election measurement technique works applicable plan by the Chu Dingre such as fluid type, still should get detailed fluid content sex to technological process branch a lot of parameter and attribute, further consideration chooses the adaptability of plan to place. Besides fluid category, the temperature that considers a fluid even normally, pressure, density, viscosity and lubricity, caustic wait with abrasion, some application place still has wholesome demand, certain measurement technique considers fluid content sex even in special parameter, use electromagnetism flowmeter to want to understand liquid electrical conductivity for example.
Meter of of all kinds flow always can be planted by the some in fluid content sex or the influence of a few kinds of parameter, so the gender is controlling the content of the fluid to treat the type that chooses appearance greatly. Place choice measurement technique and appearance should suit to be measured not only the property of the fluid, some of sex of content of the fluid in considering to measuring a process even joins the influence quantity that measures change.
Pressure of common fluid density, viscosity, vapour and other parameter are OK check from inside manual, evaluate the fluid falls in use condition each parameter and the adaptability with normative technology of appearance of place make choice of. However character of the precise class status that regular meeting encounters very not clear fluid, temperature and pressure change, flow, want an user to decide a fluid the value of each content sex is inconvenient, answer to seek advice to the manufactory right now, the appearance that estimation drafts make choice of can be denied use.
