Sõna „annustamine“ kasutavad insenerid väga sageli soojuselektrijaamades, veepuhastuses, igas tööstusharus, kus auru toodetakse, ning kütte- ja jahutusvee töötlemise teenuste ehitamisel, kusjuures annustamisprotseduurid on moes ka tekstiilitööstuses ja sarnastes tööstusharudes, kus on tegemist keemilise töötlemisega.
