Maqolada benzinning hajmiy sarfini o‘lchashda harorat omilini hisobga olish va yakuniy natijaning o‘lchash noaniqligini baholash masalalari metrologik nuqtayi nazardan tahlil qilinadi. Suyuqlik hajmining haroratga bog‘liqligi sababli o‘lchash sharoitidagi hajmiy sarfni belgilangan tayanch haroratga keltirish zarurati asoslanadi. ASTM D1250/API MPMS 11.1 hujjatidagi hajmni harorat va bosim bo‘yicha tuzatish yondashuvi hamda JCGM 100:2008 (GUM) qo‘llanmasidagi noaniqlikni ifodalash tamoyillari o‘zaro farqlanadi va bitta metrologik model doirasida ko‘rib chiqiladi. Kirish kattaliklari, ehtimoliy ta’sir etuvchi omillar, noaniqlik byudjeti va eksperimental tekshiruv mezonlari taklif etiladi. Ish nazariy-metodik xarakterga ega: haqiqiy laboratoriya ma’lumotlari berilmagani sababli sonli tajriba natijalari yoki aniqlikning yaxshilanish foizi keltirilmaydi. Taklif etilgan modelni aniq sarf o‘lchagich, benzin turi va laboratoriya sharoitida tekshirish zarurligi qayd etiladi.
