Kweyona nkqubo yokulinganisa, izinto eziqhelekileyo ezichaphazela umlinganiselo ziquka le miba mithathu ilandelayo:
Izinto eziqhelekileyo 1, iindawo ezingaboniyo
Ummandla oyimfama lixabiso lomda we-ultrasonic level gauge ukulinganisa inqanaba le-liquid, ngoko ke inqanaba eliphezulu le-liquid akufanele libe phezulu kunendawo eyimfama. Ubungakanani bendawo eyimfama yokulinganisa ihambelana nomgama wokulinganisa we-ultrasonic. Ngokuqhelekileyo, ukuba uluhlu luncinci, indawo eyimfama incinci; ukuba uluhlu lukhulu, indawo eyimfama inkulu.
Izinto eziqhelekileyo ze-2, uxinzelelo kunye nobushushu
Imilinganiselo yezinga le-ultrasonic ngokuqhelekileyo ayinakufakwa kwitanki ngoxinzelelo, kuba uxinzelelo luya kuchaphazela umlinganiselo wezinga. Ukongeza, kukho ubudlelwane obuthile phakathi koxinzelelo kunye nobushushu: T=KP (K yinto engatshintshiyo). Ukutshintsha koxinzelelo kuya kuchaphazela utshintsho lweqondo lokushisa, oluchaphazela ukuguqulwa kwesantya somsindo.
Ukuze kuhlawulwe utshintsho lweqondo lobushushu, i-ultrasonic level gauge probe ixhotyiswe ngokukodwa ngesivamvo sobushushu ukuze ihlawule ngokuzenzekelayo ifuthe lobushushu. Xa i-probe ithumela umqondiso wokubonisa kwiprosesa, iphinda ithumele isignali yeqondo lokushisa kwi-microprocessor, kwaye iprosesa iya kuhlawulela ngokuzenzekelayo umphumo wokutshintsha kweqondo lokushisa kumlinganiselo wezinga lolwelo. Ukuba i-gauge yezinga le-ultrasonic ifakwe ngaphandle, kuba ukushisa kwangaphandle kutshintsha kakhulu, kucetyiswa ukuba kufakwe i-sunshade kunye neminye imilinganiselo yokunciphisa impembelelo yokushisa kwimilinganiselo yesixhobo.
Izinto eziqhelekileyo 3, umphunga wamanzi, inkungu
Ngenxa yokuba umphunga wamanzi ulula, uya kunyuka kwaye udada ukuya phezulu kwitanki, wenze umaleko womphunga ofunxayo kwaye usasaze iipulses ze-ultrasonic, kunye namathontsi amanzi ancanyathiselwe kwi-probe ye-ultrasonic level gauge ngokulula aphendule amaza e-ultrasonic akhutshwa yi probe, kubangela ukukhutshwa Umahluko phakathi kwexesha kunye nexesha elifunyenweyo alichanekanga, nto leyo ekugqibeleni ekhokelela ekubalweni okungachanekanga komgangatho wolwelo. Ngoko ke, ukuba umlinganiselo wolwelo olulinganisiweyo ulungele ukuvelisa umphunga wamanzi okanye inkungu, i-ultrasonic level gauges ayifanelekanga ukulinganisa. Ukuba i-gauge yezinga le-ultrasonic iyimfuneko, i-waveguide ifaka i-lubricant kumphezulu weprobe, okanye ufake i-gauge ye-ultrasonic level oblique ukwenzela ukuba amathontsi amanzi angabanjwa, ngaloo ndlela kuncitshiswe impembelelo yamathontsi amanzi kumlinganiselo. iimpembelelo.
