Zotsatira za Ma Flow Meters

Mitundu ya Zotulutsa za Flow Meter

Zotsatira za Analog

1. Kutulutsa kwa Voltage
   Ma flow meters ambiri amapereka mphamvu yochokera ku magetsi (analog output). Mwachitsanzo, mphamvu yofanana ingakhale 0 - 5V kapena 0 - 10V. Mphamvu ya magetsi imafanana ndi mphamvu yoyezera ya magetsi. Pamene mphamvu yoyendera ili pamlingo wocheperako womwe ungadziwike mkati mwa mphamvu ya mita, mphamvu yotuluka imakhala kumapeto kwa sikelo, mwachitsanzo 0V. Pamene mphamvu yoyendera ikukwera molunjika, mphamvu yotuluka imawonjezekanso mofanana mpaka itafika pamlingo wapamwamba (monga 5V kapena 10V) pamlingo wapamwamba kwambiri wa magetsi womwe mita imayesedwa kuti iyese. Mtundu uwu wa mphamvu yotuluka ndi wothandiza pa ntchito zomwe chipangizo cholandirira, monga chowongolera chosavuta kapena cholozera deta chokhala ndi njira zolowera za analog, zimatha kutanthauzira mosavuta ndikukonza chizindikiro cha magetsi.
2. Zotsatira Zamakono
   Chizunguliro cha magetsi cha 4 - 20mA ndi muyezo wogwiritsidwa ntchito kwambiri m'dziko la mafakitale. Mu dongosololi, 4mA ikuyimira kuchuluka kwa kayendedwe ka madzi kochepa (kutuluka kwa madzi nthawi zambiri kumakhala kofanana ndi 4mA kuti kusiyanitse ndi sensa yosweka kapena yolumikizidwa, pomwe mphamvu yamagetsi imakhala 0mA), ndipo 20mA ikufanana ndi kuchuluka kwa kayendedwe ka madzi. Ubwino wa mphamvu yamagetsi kuposa mphamvu yamagetsi ndi chitetezo chake chachikulu ku phokoso lamagetsi pakadutsa chingwe chachitali. Izi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito komwe mita yamagetsi imayikidwa pamalo ochitira phokoso m'mafakitale kapena pamene chizindikiro chikufunika kutumizidwa patali kwambiri kupita ku chipinda chowongolera.

Zotsatira za digito

1. Kutulutsa kwa Pulse
   Ma flow meter okhala ndi pulse output amapanga ma pulse amagetsi. Chiwerengero cha ma pulse pa unit ya nthawi chimagwirizana mwachindunji ndi flow rate. Mwachitsanzo, flow meter ikhoza kuyesedwa kotero kuti pa lita iliyonse yamadzimadzi omwe amadutsa, imapanga ma pulse angapo, mwachitsanzo ma pulse 100 pa lita. Mwa kuwerengera ma pulse awa panthawi inayake, kuchuluka konse kwa madzimadzi kumatha kuwerengedwa. Ma pulse outputs amagwiritsidwa ntchito nthawi zambiri m'mapulogalamu komwe ma circuit owerengera angagwiritsidwe ntchito mosavuta, monga m'makina ena otsika mtengo owunikira flow kapena m'malo omwe chipangizo cholandirira chili ndi mphamvu zowerengera pulse.
2. Zotsatira Zolumikizirana Zotsatizana
   Pali njira zosiyanasiyana zolumikizirana zomwe zimagwiritsidwa ntchito popereka ma flow meter outputs. RS - 232, RS - 485, ndi Modbus ndi ena mwa otchuka kwambiri. Ndi RS - 232, deta imatumizidwa motsatizana pakati pa flow meter ndi chipangizo cholandirira, monga kompyuta kapena programmable logic controller (PLC). RS - 485, kumbali ina, imatha kuthandizira zida zingapo pa basi imodzi ndipo ili ndi mtunda wautali wotumizira poyerekeza ndi RS - 232. Modbus ndi protocol yogwiritsidwa ntchito kwambiri yomwe ingagwiritsidwe ntchito pa RS - 485 ndi Ethernet. Kudzera mu ma serial communication outputs awa, flow meter imatha kutumiza osati mtengo wa flow rate wapano komanso zambiri zowonjezera monga cumulative flow, status flags (zosonyeza ngati meter ikugwira ntchito bwino kapena yapeza cholakwika), ndi deta yowerengera. Zambirizi ndizofunika kwambiri panjira zovuta zamafakitale komwe kumafunika kuyang'anira ndi kuwongolera kwathunthu.

Zotulutsa Zopanda Waya

M'zaka zaposachedwapa, chifukwa cha kupita patsogolo kwa ukadaulo wopanda zingwe, ma flow meter akuchulukirachulukira kukhala ndi mphamvu zotulutsa zopanda zingwe. Bluetooth, Wi-Fi, ndi ZigBee ndi zina mwa njira zopanda zingwe zomwe zimagwiritsidwa ntchito. Bluetooth ndi yoyenera kulumikizana kwapafupi, nthawi zambiri imagwiritsidwa ntchito pamapulogalamu pomwe katswiri amafunika kupeza mwachangu deta ya flow meter pogwiritsa ntchito foni yam'manja, monga pakukonza kapena kuthetsa mavuto pamalopo. Wi-Fi imalola kusamutsa deta mwachangu pamalo akulu, zomwe zimathandiza kuti deta ya flow meter iphatikizidwe mosavuta mu netiweki yayikulu ya fakitale ndikufikiridwa kuchokera m'malo osiyanasiyana. ZigBee, yokhala ndi mphamvu zochepa zogwiritsira ntchito komanso kuthekera kwake kodzichiritsira, ndi yothandiza pamapulogalamu pomwe ma flow meter ambiri amafunika kulumikizidwa mumakampani akuluakulu, ndipo kusunga mphamvu ndi kulumikizana kodalirika ndikofunikira kwambiri.

Pomaliza, zotsatira zachoyezera kuyenda kwa madziimabwera m'njira zosiyanasiyana, iliyonse ili ndi ubwino wake komanso ntchito zake. Kusankha mtundu wa zotuluka kumadalira zinthu monga mtundu wa ntchito, mtunda womwe chizindikirocho chikufunika kuyenda, mtundu wa chipangizo cholandirira, komanso zovuta za dongosolo lonse lomwe choyezera madzi chimalumikizidwa. Kumvetsetsa njira zosiyanasiyana zotulutsira madzi ndikofunikira kuti mainjiniya ndi ogwiritsa ntchito agwiritse ntchito bwino deta ya flow meter pokonza njira zamafakitale.
