A: Hauv V-txoj kev ob qho tib si transducers zaum ntawm tib sab thiab lub teeb pom kev hauv cov yeeb nkab; nyob rau hauv Z-txoj kev lawv zaum ntawm sab nraud thiab cov nqaj hla ncaj qha. Z- feem ntau xaiv txoj hauv kev rau cov kav dej loj, phab ntsa tuab, lossis tsis muaj zog- cov teeb liab.
Q: Puas tuaj yeem ultrasonic flow meter ua haujlwm ntawm cov kav dej qub lossis xeb?
A: Feem ntau, yog tias koj ntxuav qhov chaw sib cuag mus rau cov khoom siv suab thiab xyuas cov phab ntsa tiag tiag. Hnyav sab hauv scaling lossis delaminated hauv ob sab phlu yog qhov kev pheej hmoo loj dua, vim tias nws cuam tshuam cov teeb liab - kuaj ntawm qhov chaw ua ntej ua.
Q: Vim li cas kuv lub 'meter' qhia xoom lossis wandering ntws?
A: Feem ntau yog vim li cas yog cov yeeb nkab uas tsis yog - tag nrho, tsis muaj zog coupling, qhov sib txawv tsis raug, lossis cov ntaub ntawv yeeb nkab tsis raug. Ua hauj lwm los ntawm lub teeb liab optimization ib ntus saum toj no ua ntej xav tias muaj teeb meem kho vajtse.
Q: Nws puas tuaj yeem nruab sab nraum zoov?
A: Yog, nrog rau kev saib xyuas ntawm qhov ntsuas qhov ntsuas, nag thiab hnub thaiv thaiv, cov qog kaw, thiab kev tiv thaiv kab mob. Tshawb xyuas lub sealing ntau dua li koj nyob hauv tsev.
Q: Yuav ua li cas yog tias tsis muaj cov ntsuas ntsuas los sib piv?
A: Siv lub twj tso kua mis nkhaus, ntsuas qib tank hloov lub sijhawm paub, lossis lub thoob -thiab- nres saib xyuas ntawm kab me me. Qhov ntsuas lub suab nrawm uas qhia los ntawm lub 'meter' kuj yog ib qho kev soj ntsuam ceev ceev ntawm koj cov ntaub ntawv yeeb nkab.

Txhim kho phab ntsa-mounted ultrasonic flow meter tsis nyuaj, tab sis antseeginstallation yog txhob txwm tshaj tawm. Xaiv ib qho tag nrho, ruaj khov ncaj- ntu yeeb nkab; sau cov yeeb nkab tiag tiag es tsis txhob twv; phim txoj kev mounting rau cov yeeb nkab; npaj lub nto thiab ob peb lub transducers kom zoo; thiab ua pov thawj qhov tshwm sim nrog kev kuaj mob, xoom kos, thiab kev nyeem ntawv siv. Txuag cov ntaub ntawv sau npe ua haujlwm raws li koj lub hauv paus - nws hloov pauv txhua qhov kev daws teeb meem yav tom ntej rau hauv kev sib piv tsis yog qhov tsis paub.
Ua ntej koj txiav txim, paub meej tias cov yeeb nkab loj, kua dej, qhov kub thiab txias, tso zis teeb liab, thiab qhov chaw ntawm qhov chaw kom cov qauv thiab transducer hom yeej haum rau txoj haujlwm. Yog tias koj xav tau qhov kev xav thib ob ntawm ib kab tshwj xeeb,qhia koj cov yeeb nkab thiab cov kua dejthiab tau txais kev pom zoo ua ntej kev teeb tsa - kev xaiv txoj cai pem hauv ntej yog thawj kauj ruam mus rau kev nyeem ntawv koj tuaj yeem tso siab rau.
Kev tshuaj xyuas los ntawm pab pawg ntsuas nrog kev ua haujlwm ua haujlwm thoob plaws dej, HVAC, thiab cov ntawv thov txheej txheem. Qhov twg cov duab sib txawv los ntawm cov khoom lag luam - ncaj- yeeb nkab ntev, lub teeb liab pib, qhov sib nrug txhais tau tias - ib txwm ncua mus rau lub ntsuas ntsuas phau ntawv.
