Iiparamitha ezine zemizi mvelisoubushushu, uxinzelelo, umgangatho wohambokwayeumgangatho wolwelo.
1. Ubushushu
Ubushushu lixabiso lomzimba elimele iqondo lokubanda kunye nobushushu bento elinganisiweyo.Ngokwendlela yokulinganisa yesixhobo sokushisa, inokwahlulwa ibe luhlobo loqhagamshelwano kunye nohlobo olungadibananga.Imitha yoqhagamshelwano yokulinganisa iqondo lobushushu ikakhulu ibandakanya ithemometha, ukumelana nobushushu kunye ne-thermocouple.Umlinganiselo wobushushu obungadibaniyo ne-instrumenet ubukhulu becala yipyrometer yokukhanya, ipyrometer yefoto yombane, ipyrometer yemitha kunye nethemometha ye-infrared.
2. Uxinzelelo
Uxinzelelo olufunyenwe kuyo nayiphi na into lubandakanya uxinzelelo lwe-atmospheric kunye noxinzelelo lwe-medium medium (ngokubanzi uxinzelelo lwe-gauge) iindawo ezimbini, isamba samacandelo amabini oxinzelelo kwinto elinganisiweyo ibizwa ngokuba luxinzelelo olupheleleyo, kunye noxinzelelo oluqhelekileyo lwamashishini. igeyiji ilinganiswa ngexabiso legeyiji, oko kukuthi, itafile yeP =P ngokupheleleyo - uxinzelelo lwe-atmospheric.
Izixhobo zokulinganisa uxinzelelo zinokwahlulwa zibe ngamacandelo amathathu: ngokomxhuzulane kunye nendlela yokulinganisa uxinzelelo olulinganisiweyo, ukulinganisa ngokuthe ngqo ubungakanani bamandla kwindawo yeyunithi, njengegeji yoxinzelelo lwekholamu yolwelo kunye ne-piston yoxinzelelo loxinzelelo;Ngokwendlela yamandla e-elastic kunye nokulinganisa ukulinganisela koxinzelelo, ukulinganisa amandla e-elastiki aveliswa yi-deformation ye-elastic element emva koxinzelelo, njengegeji yoxinzelelo lwe-spring, i-bellow gauge yoxinzelelo, igeji yoxinzelelo lwe-diaphragm kunye ne-diaphragm ye-pressure gauge yebhokisi;Sebenzisa iipropathi ezibonakalayo zezinye izinto ezinxulumene noxinzelelo, ezifana nombane ombane okanye ukuxhathisa okanye utshintsho lwecapacitance xa ucinezelekile;Umzekelo, iinzwa zoxinzelelo.
3. Phula
Kwimveliso kunye nolawulo lwamashishini, ukufumanisa ipharamitha yokuhamba kwamanzi kunye nokulawula yenye yezona pharamitha eziqhelekileyo.Kukho iintlobo ezininzi zeemitha ezisetyenziselwa ukulinganisa ukuhamba, kubandakanya i-flowmeter ye-ultrasonic, i-electromagnetic flowmeter, i-throttling flowmeter kunye ne-volumetric flowmeter.
4. Inqanaba
Inqanaba lolwelo libhekisa kwinqanaba lolwelo kwisikhongozeli esitywiniweyo okanye kwisikhongozeli esivulekileyo.Izixhobo eziqhelekileyo ezisetyenziselwa ukulinganisa inqanaba lolwelo yimitha yenqanaba le-ultrasonic, imitha yenqanaba leglasi, imitha yomgangatho woxinzelelo, imitha yenqanaba lebhola edadayo, imitha yenqanaba le-buoy, imitha yomgangatho wepleyiti yebhola edadayo, imitha yenqanaba leradar, imitha yenqanaba le-radioactive, inqanaba lokungena kwirediyo. imitha, njl.
