Ushbu maqolada ochiq o‘zanlarda suv sarfini o‘lchashga mo‘ljallangan “Smart
Channel” qurilmasining laboratoriya sharoitida metrologik ko‘rsatkichlarini baholash va kalibrlash
metodikasi yoritilgan. Tadqiqot obyekti sifatida balandligi va eni 80×80 sm bo‘lgan qurilma namunasi
tanlandi. Tajribalar Toshkent viloyati Quyi Chirchiq tumanidagi “SmartSolutionsSystem”MCHJning
“Gidravlika va gidrometriya” laboratoriyasida olib borildi. Qurilma tezlik–maydon usuli asosida
ishlaydi, ya’ni suv sarfi oqimning o‘rtacha tezligi va tirik kesim yuzasi orqali aniqlanadi. Oqim tezligi
8 qatorga joylashtirilgan jami 32 ta ultratovushli datchik yordamida qatlamlar bo‘yicha qayd etiladi
va umumiy o‘rtacha tezlik hisoblanadi. Tadqiqot davomida qurilmaning maksimal suv o‘tkazish
qobiliyati, elektromagnit etalon suv sarfini o‘lchash vositasi va hajmiy usul bilan solishtirishdagi
xatoliklari aniqlandi. Dastlabki sinovlarda maksimal suv sarfi 799,23 l/s bo‘lib, xatoliklar 5,98
%dan14,30 % gacha yetdi. Bu holat yuqori sarf rejimlarida qurilmaning boshlang‘ich hisoblash
algoritmini takomillashtirish zarurligini ko‘rsatdi. Shu sababli etalon va hajmiy usul natijalari asosida
kalibrlash koeffitsienti ishlab chiqilib, qurilma dasturiga kiritildi. Kalibrlashdan so‘ng maksimal suv
sarfi 890,57 l/s gacha oshdi, xatoliklar esa 2,47 % dan +2,37 % gacha kamaydi. Natijalar qurilmani
qiyoslash va kalibrlash uning aniqligini sezilarli yaxshilashini, ochiq o‘zanlarda suv sarfini raqamli
usulda ishonchli o‘lchash uchun ilmiy-amaliy asos yaratishini ko‘rsatdi, shuningdek qurilmani keng
amaliyotga samarali joriy etish imkoniyatlarini ilmiy asoslashga xizmat qiladi.
