Flow meter, what is and how use it?

Hi folks. There been a while I didn't wrote something about basic principle. And for this session, I would like to write about Flow Meter. Flow meter is the quantification of bulk and fluid movements . Flow are generally measured in many different ways. Positive-displacement flow meters accumulate a set volume of fluid and then count the number of times the volume is filled to measure flow. Other flow measurement methods depend on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.

Determine paper packaging for eco friendly reason.

Another excellent way for businesses to manage extraneous waste and go green is by implementing the use of paper packaging materials for outbound small parcel shipping. Both are legitimate types of recycled content in that both must comply with the same standard: Any recycled content claim for eco friendly packaging materials made of paper, whether Post Industrial or Post Consumer, may only be made when the content is made up of material that has been diverted from the waste stream.

Sodium Metabishulphate as Antistatic Agent

Sodium metabisulphite is a kind of white or slightly yellow crystalline powder.

It is soluble in water, acidic aqueous solution. Besides, it also is soluble in glycerol, slightly soluble in ethanol. And it is easily decompose when sodium metabisulfite 97% becomes wet antistatic agent. When exposed in air it will easily oxidize into sulfate. Emit sulfur dioxide and generate the corresponding salts when Sodium pyrosulfite contacts with acid. Sodium metabisulfite 96.5% powder will decompose when heated to 150 ℃.
