Intelligent open channel flow measurement system-integrated gate control, full channel width flowmeter yog tib lub ntse qhib channel flowmeter uas tuaj yeem ntsuas ncaj qha qhov nruab nrab ntws tshaj tawm ntawm ntu ntws.
Ultrasonic puv channel dav-qhib channel ntws ntsuas qhov system siv qhov ntsuas nrawm thiab thaj chaw ntsuas raws li cov qauv ntsuas yooj yim.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub kaw lus yog ntsuas ncaj qha ntsuas qhov nrawm ntawm cov txheej txheem sib txawv ntawm cov dej ntws los ntawm kev tso cov ultrasonic ntws nrawm sensor qhov system sib npaug ntawm qhov ntws hla ntu, thiab tau txais cov ntaub ntawv zoo tshaj plaws khiav tawm los ntawm cov algorithm. Qhov nruab nrab ntws nrawm ntawm ntu ntws yog muab faib los ntawm thaj tsam ntawm ntu kom tau txais qhov nrawm nrawm. Kev ntsuas dej feem ntau siv ultrasound, siab, ntab, thiab lwm yam.
Piv nrog rau lwm txoj kev ntsuas ntsuas tam sim no, qhov system no ncaj qha tau qhov nruab nrab qhov nrawm, thiab tom kawg tau txais qhov nruab nrab qhov nruab nrab tshaj tawm lossis qhov nruab nrab tshaj tawm. Feem ntau, qhov ntsuas qhov tseeb ntawm qhov system yog siab dua.
Nta:
Lub ntsuas ntsuas ntsuas tau ntsuas cov kua dej, qhov nruab nrab ntws tus nqi, thiab accumulative los yog instantaneous flow;
Cov qauv lej tsim nyog ntxiv rau cov thev naus laus zis siab heev thiab ntau khub ntawm ultrasonic velocity sensors rau kev ntsuas kev ntsuas tuaj yeem ntsuas qhov sib txawv ntawm cov ntu ntws nrawm;
Kev ntsuas dav: 0.01-10 m / s;
Kev ntsuas ob-txoj kev ntws;
Cov txheej txheem kev tshem tawm nto tuaj yeem ntsia tau ncaj qha yam tsis muaj kev hloov kho, kev teeb tsa thiab kev tsim kho tsis yooj yim thiab tus nqi qis;
Cov cuab yeej tso saib muaj nuj nqi: tso saib cov dej theem, instantaneous flow ntawm seem, accumulative flow, thiab lwm yam.;
Kev siv lub rooj txhawb nqa tuaj yeem paub qhov tseeb ntsuas thiab tswj kev sib koom ua ke;
Cov ntaub ntawv khaws cia ruaj khov muaj nuj nqi, tuaj yeem txuag cov teeb tsa tsis tau thiab ntws tus nqi nyob rau hauv rooj plaub ntawm lub zog tsis ua haujlwm ntev;
Cov cuab yeej muaj tus qauv MODBUS (RTU) tso zis 485 interface, 4-20MA dual analog input interface rau kev txhawb nqa kev siv
