Kumvetsetsa Mitundu Iwiri ya Ukadaulo wa Ultrasonic Flowmeter

Ma ultrasound flow meter amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana poyesa kuyenda kwa madzi ndi mpweya. Amadziwika chifukwa cha kulondola kwawo, kudalirika kwawo, komanso kusawononga zinthu, zomwe zimapangitsa kuti akhale chisankho chodziwika bwino pa ntchito zambiri. Pali mitundu iwiri ikuluikulu ya ukadaulo wa ultrasound flowmeter: njira yodutsa nthawi ndi njira ya Doppler. Mu blog iyi, tiwona kusiyana pakati pa ukadaulo uwu ndi ntchito zake.

Mfundo yogwira ntchito ya ultrasound time flow flow meter ndi kuyeza nthawi yomwe imatenga kuti chizindikiro cha ultrasound chifalikire mmwamba ndi pansi pa payipi. Kusiyana kwa nthawi yodutsa kumagwirizana ndi kuchuluka kwa madzi. Ukadaulo uwu ndi wabwino kwambiri pa madzi oyera, ofanana okhala ndi tinthu tating'onoting'ono kapena thovu la mpweya. Umagwiritsidwa ntchito kwambiri pa ntchito monga kasamalidwe ka madzi ndi madzi otayira, machitidwe a HVAC, ndi machitidwe amafakitale komwe madziwo alibe zinyalala.

Kumbali inayi, ma Doppler ultrasonic flow meter amagwiritsa ntchito Doppler effect poyesa kuchuluka kwa madzi. Ukadaulowu umagwira ntchito potulutsa zizindikiro za ultrasound zomwe zimawonetsedwa ndi tinthu tating'onoting'ono kapena thovu mumadzi. Kusintha kwa pafupipafupi kwa chizindikiro chowonetsedwa kumagwiritsidwa ntchito kuwerengera kuchuluka kwa madzi. Ma Doppler flowmeter ndi oyenera madzi okhala ndi tinthu tating'onoting'ono tomwe timayimitsidwa kapena thovu la mpweya, zomwe zimapangitsa kuti zikhale chisankho choyamba pakugwiritsa ntchito matope, madzi otayira okhala ndi zinthu zolimba komanso zakumwa zopumira.

Kusiyana kwakukulu pakati pa ma ultrasound time flow meter ndi ma Doppler ultrasonic flow meter ndi koyenera kugwiritsa ntchito mitundu yosiyanasiyana ya madzi. Ngakhale kuti ma transit meter amagwira ntchito bwino m'madzi oyera komanso ofanana, ma Doppler meter ndi oyenera kwambiri kugwiritsa ntchito madzi omwe ali ndi zinyalala kapena omwe ali ndi mpweya. Posankha ukadaulo woyenera wa ultrasound flow meter wogwiritsidwa ntchito pa ntchito inayake, ndikofunikira kuganizira za mawonekedwe a madzi omwe akuyesedwa.

Chinthu china choyenera kuganizira ndi kukula kwa chitoliro ndi zinthu. Ma flow meters a ultrasonic nthawi yodutsa ndi abwino kwambiri pamitundu yosiyanasiyana ya mapaipi ndi zinthu, kuphatikizapo zitsulo, pulasitiki ndi konkire. Amapezeka pamapaipi ang'onoang'ono ndi akuluakulu, zomwe zimapangitsa kuti akhale oyenera kuyika zinthu zosiyanasiyana. Koma ma Doppler flowmeters angakhale ndi zoletsa pakukula kwa chitoliro ndi kugwirizana kwa zinthu chifukwa kupezeka kwa tinthu tating'onoting'ono kapena thovu la mpweya m'madzimadzi ndikofunikira kwambiri pakugwira ntchito kwawo.

Kuwonjezera pa makhalidwe amadzimadzi ndi kuganizira za mapaipi, kukhazikitsa ndi kukonza mita yoyendera madzi pogwiritsa ntchito ma ultrasound kuyeneranso kuganiziridwa. Ngakhale kuti mita yoyendera nthawi zambiri imafuna mapaipi owongoka kuti ipange miyeso yolondola, mita ya Doppler ikhoza kukhala yomasuka kwambiri pankhani ya zofunikira pakuyiyika chifukwa cha kuthekera kwawo kugwira ntchito pamaso pa tinthu tating'onoting'ono kapena thovu.

Mwachidule, kumvetsetsa mitundu yonse iwiri ya ukadaulo wa ultrasound flow meter (nthawi yosinthira ndi Doppler) ndikofunikira kwambiri posankha yankho loyenera la ntchito inayake. Poganizira mtundu wa madzi, kukula kwa chitoliro ndi zinthu, komanso zofunikira pakukhazikitsa ndi kukonza, ogwiritsa ntchito amatha kupanga zisankho zodziwikiratu kuti atsimikizire kuyeza kolondola komanso kodalirika kwa madzi. Kaya kuyang'anira kuyenda kwa madzi m'dongosolo la boma kapena kuyeza kuyenda kwa slurry munjira yamafakitale, kusankha pakati pa nthawi yodutsa ultrasonic flow meter ndi Doppler ultrasonic flow meter kungakhale ndi zotsatira zazikulu pakugwira bwino ntchito kwa yankho loyezera.
