Lub cev daim ntawv ntawm cov kua theem sensor txawv nyob ntawm nws cov kev khiav hauj lwm txoj cai thiab lub hom phiaj daim ntawv thov, txawm hais tias lawv muaj peev xwm muab faib ua ob peb hom qauv. Float- hom kua theem sensors feem ntau feature ib tug elongated pas nrig los yog tubular qauv, raws li ib tug los yog ntau tshaj floats yog positioned mus rau vertically nyob rau hauv tandem nrog cov kua theem rau kev tshawb nrhiav lub hom phiaj; Qhov kev tsim no feem ntau siv rau hauv cov khoom siv xws li cov tso dej tso dej thiab cov nkoj cia.
Capacitive thiab electrode- hom kua qib sensors feem ntau muaj cov qauv yooj yim dua- feem ntau muaj cov kab nrib pleb lossis pas nrig -zoo li cov qauv- ua kom yooj yim raus nkag mus rau hauv cov kua rau kev ntsuas tas li. Cov sensors no muaj cov qauv tsim compact uas tsis muaj qhov tseem ceeb txav, ua rau lawv zoo- haum rau kev teeb tsa hauv ib puag ncig uas tsis muaj chaw lossis qhov chaw ua haujlwm siab yog qhov tseem ceeb.
Ultrasonic kua theem sensors, sib txawv, zoo li yuav txais ib tug "lub taub hau-thiab-tsev" configuration; seem sab sauv feem ntau nta ib lub voj voog lossis tiaj tus transducer sojntsuam, txuas hauv qab no rau lub tsev nyob hauv hluav taws xob, tsim los rau nruab rau saum lub thawv rau tsis yog -kev ntsuas. Tsis tas li ntawd, qee yam kev lag luam - qib kua qib sensors tuaj yeem siv cylindrical, tawg- pov thawj, lossis flange - cov qauv tsim kom ua raws li cov qauv kev lag luam sib txawv thiab ua tau raws li cov kev xav tau tshwj xeeb.
