I-frequency yokusebenza esetyenziswa zii-ultrasonic flowmeters idla ngokuba phakathi kwe-1MHz kunye ne-5MHz, apho i-2MHz yeyona frequency ixhaphakileyo. Abavelisi bee-flowmeter ezahlukeneyo banokukhetha ii-frequency ezahlukeneyo, kuxhomekeke kubuchwepheshe babo kunye noyilo lwemveliso. Nangona kunjalo, kubaluleke kakhulu ukukhetha i-frequency yokusebenza efanelekileyo kuba ii-frequency ezahlukeneyo zinokubonelela ngeenzuzo kunye neengxaki ezahlukeneyo.
Kwiifrikhwensi ezisezantsi, ezifana ne-1MHz, ukuchaneka kokulinganisa kuphezulu. Oku kungenxa yokuba imiqondiso yefrikhwensi esezantsi iyabola kancinci, ingahamba ihambele phambili, kwaye, kwiincindi ezininzi, iya kubonakala izihlandlo ezininzi kulwelo. Oku kunokubonelela ngedatha engaphezulu, nto leyo ephucula ukuchaneka kokubala.
Nangona kunjalo, kubushushu obuphantsi okanye kubushushu obuphezulu, obuqulethe iintlobo ngeentlobo zeegesi okanye indawo enegesi eninzi, ukusetyenziswa kwee-flowmeters ze-ultrasonic ezisebenzisa i-frequency ephantsi kuya kubangela iingxaki ezithile. Kule meko, isignali ye-ultrasonic inokufunxwa okanye isasazwe ziigesi ezikwindawo, nto leyo echaphazela ukuchaneka komlinganiselo.
Ngokwahlukileyo koko, kwiifrikhwensi eziphezulu, njenge-5MHz, imitha inokuhlengahlengiswa ngcono kwimeko-bume engentla. Imiqondiso yefrikhwensi ephezulu ibola ngokukhawuleza kwaye ingene kakuhle kwigesi, kwaye ayifunxwa lula okanye isasazwe yigesi, ngaloo ndlela isebenza ngcono. Nangona kunjalo, imiqondiso ye-ultrasonic yefrikhwensi ephezulu ibola ngokukhawuleza kwaye ilahlekelwa ngamandla amaninzi ngexesha lokudluliselwa.
Ngokubanzi, ukukhethwa kwesantya sokusebenza kwe-ultrasonic flowmeter kufuneka kuqwalaselwe imeko-bume yokusetyenziswa kunye neemfuno zokulinganisa. Ngokubanzi, ii-2MHz ultrasonic flowmeters zezona zisetyenziswa kakhulu kwaye zinokuhlangabezana neemfuno zoninzi lwemilinganiselo yokuhamba.
