Iiparameter ezine eziphambili zoshishino zibubushushu, uxinzelelo, izinga lokuhamba kwamanzi, kunye nenqanaba lolwelo.
I. Ubushushu (T) Ubushushu bubungakanani obubonakalayo obubonisa inqanaba lobushushu okanye ukubanda kwento elinganisiweyo. Ngokweendlela zokulinganisa izixhobo zobushushu, zinokwahlulwa zibe ziindidi ezimbini: uhlobo loqhagamshelwano kunye nohlobo olungenaqhagamshelwano. Izixhobo zokulinganisa ubushushu boqhagamshelwano ziquka ikakhulu ii-thermometers, ii-thermal resistor, kunye nee-thermocouples. Izixhobo zokulinganisa ubushushu obungenanxibelelwano ziquka ikakhulu ii-optical pyrometers, ii-photoelectric pyrometers, ii-radiation pyrometers, kunye nee-infrared thermometers.
II. Uxinzelelo (P) Uxinzelelo olusebenza kuyo nayiphi na into lunamacandelo amabini: uxinzelelo lomoya kunye noxinzelelo lwendlela elinganisiweyo (idla ngokuba luxinzelelo lokulinganisa). Isimbuku sezi nxalenye zimbini zoxinzelelo olusebenza kwinto elinganisiweyo sibizwa ngokuba luxinzelelo olupheleleyo. Kwaye iigeyiji zoxinzelelo zemizi-mveliso eziqhelekileyo zilinganisa ixabiso loxinzelelo lokulinganisa, oko kukuthi, i-P gauge = P absolute – uxinzelelo lomoya. Izixhobo zokulinganisa uxinzelelo zinokwahlulwa zibe ziindidi ezintathu: Ngendlela yokulinganisa amandla axhuzulayo noxinzelelo olulinganisiweyo, linganisa ngokuthe ngqo ubukhulu bamandla kwindawo nganye, njengeegeyiji zoxinzelelo lwekholamu yolwelo kunye neegeyiji zoxinzelelo lwepiston; Ngendlela yokulinganisa amandla e-elastic noxinzelelo olulinganisiweyo, linganisa ubukhulu bamandla e-elastic aveliswa kukuguqulwa kwento e-elastic phantsi koxinzelelo, njengeegeyiji zoxinzelelo zetyhubhu yeBourdon, iigeyiji zoxinzelelo ze-bellows, iigeyiji zoxinzelelo lwe-diaphragm, kunye neegeyiji zoxinzelelo lwe-capsule; Sebenzisa iipropati zomzimba zezinto ezithile ezinxulumene noxinzelelo, njengotshintsho kwi-voltage, ukumelana, okanye i-capacitance xa uphantsi koxinzelelo, umzekelo, ii-sensors zoxinzelelo.
III. Izinga lokuhamba (Q) Kwimveliso nolawulo lwemizi-mveliso, ukufunyanwa nokulawulwa kweeparamitha zezinga lokuhamba kolwelo yenye yezona parameter zixhaphakileyo. Kukho izixhobo ezahlukeneyo zokulinganisa izinga lokuhamba, ikakhulu kuquka ii-ultrasonic flowmeters, ii-electromagnetic flowmeters, ii-throttling flowmeters, kunye nee-positive displacement flowmeters.
IV. Inqanaba lolwelo (H) Inqanaba lolwelo libhekisa kubude benqanaba lolwelo kwisikhongozeli esivaliweyo okanye kwisikhongozeli esivulekileyo. Izixhobo ezisetyenziswa rhoqo ukulinganisa inqanaba lolwelo ziquka iimitha zenqanaba le-ultrasonic, iimitha zenqanaba le-glass plate, iimitha zenqanaba loxinzelelo oluhlukeneyo, iimitha zenqanaba lokudada, iimitha zenqanaba le-float drum, iimitha zenqanaba le-float magnetic flap, iimitha zenqanaba le-radar, iimitha zenqanaba le-radioactive, kunye neemitha zenqanaba le-radio frequency admittance.
