imitha yokuhamba kwe-vortexsisilinganisi sokuqukuqela komthamo werhasi, umphunga okanye ulwelo, ukuhamba komthamo weemeko eziqhelekileyo, okanye ukuhamba kobunzima berhasi, umphunga okanye ulwelo olusekelwe kumgaqo wevortex. Namhlanje, umenzi we-flowmeter Q&T Instrument upasise eli nqaku Uchaza iindlela ezininzi zokusetyenzwa, kwaye unokuziqokelela ukuba uyazifuna.
1Qala ngokuqinisekisa ukuba kukho itrafikhi.
2. Khangela umbane wombane, i-voltage kwiipali ezilungileyo kunye ne-negative kufuneka ibe phakathi kwe-10.5-50VDC.
(1). Ukuba i-voltage ingu-zero, khangela i-fuse yonikezelo lwamandla;
(2). Ukuba i-voltage iphantsi kakhulu kodwa ayikho i-zero, i-flowmeter inokuxhotyiswa ngomthombo wamandla. Vula i-terminal cover cover, qhawula iipali ezilungileyo nezingalunganga, kwaye ulinganise umbane wokubonelela. Ukuba i-voltage iyinto eqhelekileyo, isiphaluka sombane kule ndawo siqhelekile, kwaye izibonda ezilungileyo kunye nezibi ziphinde zixhunywe;
(3). Vula isigqubuthelo sodwa semodyuli ye-elektroniki, qhawula iingcingo ezibomvu neziluhlaza kwiitheminali zocingo phambi kwemodyuli ye-elektroniki, umlinganiselo wombane phakathi kocingo olubomvu kunye nocingo oluluhlaza, ukuba i-voltage iyinto eqhelekileyo, imodyuli yombane yonakele. , buyisela imodyuli yombane;
(4). Ukuba i-voltage isephantsi, i-case / terminals yonakaliswe, buyisela ityala okanye ubuyisele imitha kwifektri ukulungiswa;
Jonga i-4-20mA output circuit;

(5). I-loop ye-4-20mA ingabonwa ngesokhethi yokuvavanya kwibhodi ye-terminal ephumayo, evelisa i-voltage signal ye-0.1-0.5 ehambelana ne-4-20mA yangoku. Ngaphambi koko, nceda uqiniseke ukuba iswitshi J icinyiwe kuba isiseko sovavanyo sipulsed Imo yokuPhuma. Oku kulandelayo akufumaneki..
3. Ukwandisa ukuhamba ukuqinisekisa ukuba
imitha yokuhamba kwe-vortexayisebenzi kwaye ingaphantsi koluhlu lokuthintela ukuhamba okuphantsi
