Mafambiro ekushanda anoshandiswa nema ultrasonic flowmeters anowanzova pakati pe1MHz ne5MHz, ayo 2MHz ndiyo frequency inonyanya kushandiswa. Vagadziri vakasiyana ve flowmeter vanogona kusarudza ma frequency akasiyana, zvichienderana netekinoroji yavo uye dhizaini yechigadzirwa. Zvisinei, zvakakosha kusarudza ma frequency akakodzera ekushanda nekuti ma frequency akasiyana anogona kupa zvakanakira nezvakaipira zvakasiyana.
Pamafrequency akaderera, akadai se1MHz, kururama kwekuyera kwakakwira. Izvi zvinodaro nekuti masaini ane mafrequency akaderera anoora zvishoma nezvishoma, anogona kufamba kure, uye, kune akawanda mafluids, anoonekwa kakawanda mumvura. Izvi zvinogona kupa data rakawanda, izvo zvinovandudza kururama kwekuverenga.
Zvisinei, kana tembiricha yakaderera kana tembiricha yakakwira, ine magasi akasiyana-siyana kana gasi rakawanda, kushandiswa kwe low frequency ultrasonic flowmeters kunokonzera mamwe matambudziko. Muzviitiko izvi, chiratidzo che ultrasonic chinogona kunyudzwa kana kuparadzirwa nemagasi ari munharaunda, nokudaro zvichikanganisa kururama kwekuyera.
Kusiyana neizvi, pamafrequencies akakwira, akadai se5MHz, mita inogona kugadziriswa zviri nani nemamiriro ezvinhu ari pamusoro apa. Masignali ehigh-frequency anoora nekukurumidza uye anopinda mugasi zviri nani, uye haanyudzwe nyore nyore kana kuparadzirwa negasi, nokudaro achiita zviri nani. Zvisinei, masignali ehigh-frequency ultrasound anoora nekukurumidza uye anorasikirwa nesimba rakawanda panguva yekutumira.
Kazhinji, kusarudzwa kwefrequency yekushanda kwe ultrasonic flowmeter kunofanirwa kufunga nezvenzvimbo chaiyo yekushandisa uye zvinodiwa pakuyera. Kazhinji, 2MHz ultrasonic flowmeters ndiyo inonyanya kushandiswa uye inogona kusangana nezvinodiwa nekuyera kuyerera kwakawanda.
