Qhov kub thiab txias qis thaum lub caij ntuj no. Yog tias lub ultrasonic flowmeter raug teeb tsa sab nraum zoov lossis ntawm cov kav dej tsis muaj kev ntsuas rwb thaiv tsev, nws yooj yim rau kev puas tsuaj vim qhov nruab nrab khov. 5 lub tswv yim hauv qab no tuaj yeem siv rau kev saib xyuas tiv thaiv kev khov:
Lub Tswv Yim 1: Ua haujlwm zoo ntawm kev rwb thaiv cua sov rau cov kav dej thiab cov khoom siv. Qhwv lub ntsuas dej thiab cov kav dej hauv 3 meters ua ntej thiab tom qab nws nruj nrog paj rwb rwb thaiv cua sov (pom zoo kom siv pob zeb wool lossis polyurethane, thiab qhov tuab ntawm rwb thaiv cua sov yog txiav txim siab raws li qhov kub tsawg kawg nkaus hauv zos, feem ntau tsis tsawg dua 50 hli). Qhwv txheej sab nraud ntawm paj rwb rwb thaiv cua sov nrog daim ntaub tsis pub dej kom tiv thaiv nag thiab daus kom tsis txhob nkag mus rau hauv thiab ua rau rwb thaiv cua sov tsis ua haujlwm. Rau thaj chaw txias hauv sab qaum teb Suav teb, cov xov hluav taws xob cua sov tuaj yeem ntsia tau rau hauv cov txheej rwb thaiv cua sov. Lub zog ntawm cov xov hluav taws xob cua sov yog 10-20W / m, uas tuaj yeem tswj cov kav dej kub siab dua 0 ℃ tom qab qhib hluav taws xob kom tiv thaiv kev khov nruab nrab.
Lub Tswv Yim 2: Xaiv qhov chaw teeb tsa kom tsim nyog. Sim teeb tsa lub ntsuas dej hauv tsev lossis hauv thaj chaw muaj kev nyab xeeb kom tsis txhob raug cua thiab daus ncaj qha. Yog tias yuav tsum tau teeb tsa sab nraum zoov, yuav tsum tsim lub tsev tiv thaiv. Qhov siab ntawm lub tsev tiv thaiv yuav tsum tsis pub tsawg dua 1.5 meters kom ntseeg tau tias muaj cua nkag tau zoo thiab tiv thaiv cov khoom siv kom tsis txhob raug tshav ntuj ncaj qha thiab nag ntub.
Lub Tswv Yim 3: Tshawb xyuas qhov xwm txheej nruab nrab tas li. Thaum lub caij ntuj no, yog tias qhov ntsuas nruab nrab yog dej lossis lwm yam kua dej yooj yim rau khov, nws yog qhov tsim nyog los tshawb xyuas qhov kub nruab nrab uas cov khoom siv tso tawm tsis tu ncua txhua hnub. Yog tias qhov kub nyob ze rau 0 ℃, qhov nrawm ntws nruab nrab tuaj yeem nce ntxiv kom raug (los ntawm kev kho lub qhov kav dej), lossis antifreeze tuaj yeem ntxiv rau qhov nruab nrab (nws yog qhov tsim nyog los paub tseeb tias antifreeze sib xws nrog cov kav dej thiab cov khoom siv kom tsis txhob xeb). Yog tias cov khoom siv tsis siv ntev, cov khoom siv hauv cov kav dej yuav tsum tau ntws tawm kom tiv thaiv kev puas tsuaj rau cov khoom siv vim khov thiab nthuav dav.
Lub Tswv Yim 4: Xyuas seb cov khoom siv puas ua haujlwm zoo. Xyuas seb daim roj hmab sealing strip ntawm lub flowmeter casing puas laus lossis puas lawm. Yog tias qhov sealing tsis zoo, nag thiab daus yuav nkag mus rau hauv cov khoom siv thiab ua rau luv luv Circuit Court. Cov silicone sealant siv tau los txhawb cov khoom kaw tsis tu ncua. Tib lub sijhawm, xyuas seb lub hau dej tsis nkag ntawm qhov chaw soj ntsuam puas zoo. Yog tias nws puas lawm, nws yuav tsum tau hloov pauv raws sijhawm kom tiv thaiv dej nkag mus rau sab hauv ntawm lub probe.
Lub Tswv Yim 5: Ua haujlwm kho mob thaum muaj xwm txheej ceev. Yog tias pom tias cov khoom siv tau khov lawm, tsis txhob yuam kom qhib lossis khob lub cuab yeej. Ua ntej, kaw lub qhov dej kom nres cov khoom siv, tom qab ntawd maj mam nchuav dej sov (kub tsis pub tshaj 60 ℃) rau ntawm qhov khov. Tom qab cov khoom siv yaj tag, xyuas seb cov khoom siv puas muaj dej xau, puas tsuaj rau cov khoom siv thiab lwm yam mob. Xyuas kom tseeb tias nws zoo li qub ua ntej qhib.
