Selection of parameters:
1) Media type to be measured (Liquid or solid, such as: Water, sewage, mud, gasoline, diesel oil, toluene, sulfur dioxide, ore, coal, cement, soybeans, wheat, corn, flour, etc.)
If it is liquid: Is there liquid steam, mist, foam, wave, stirring, floating objects;
If it is solid: Is there a dust, granular or powder media is.
2) The minimum ~ maximum temperature and pressure of media.
3) Corrosion of media. If it is placed inside the jar, the jar needs to know the material, and if there is corrosion of the lining.
4) The need for anti-corrosion, explosion-proof, to split or an integrated one?
5) Working environment: exposure to the pond, cover the pond, liquid tank, pot is through atmospheric pressure and so on.
6) Power Supply: 12 to 24VDC
