Kubuda kweMamita Ekuyerera

Mhando dzeMiyero yeKubuda kweMamita eKuyerera

Zvinobuda muAnalog

1. Kubuda kweVoltage
   Mazhinji maflow meters anopa voltage-based analog output. Semuenzaniso, common range inogona kuva 0 - 5V kana 0 - 10V. Voltage value inoenderana ne flow rate yakayerwa. Kana flow rate iri pa low content content mukati me meter range, output voltage iri pa low end of the scale, ngatitii 0V. Sezvo flow rate ichiwedzera linearly, output voltage inowedzerawo proportionally kusvika yasvika pa highest value (semuenzaniso, 5V kana 10V) pa maximum flow rate iyo meter inogadziriswa kuti ionekwe. Rudzi urwu rwe output runobatsira kuma applications apo receiving device, senge simple controller kana data logger ine analog input channels, inogona kududzira uye kugadzirisa voltage signal zviri nyore.
2. Zvinobuda Pari Zvino
   Chinotenderera chemagetsi che4 - 20mA chinoshandiswa zvakanyanya munyika yeindasitiri. Mugadziriro iyi, 4mA inomiririra mwero wepasi wekuyerera (zero flow inowanzo deredzwa kusvika ku4mA kuti isiyaniswe nesensor yakatyoka kana yakabviswa, uko magetsi angave 0mA), uye 20mA inoenderana nemwero wepamusoro wekuyerera. Kubatsira kwemagetsi ekubuda kupfuura magetsi ndiko kusadzivirira ruzha rwemagetsi panguva yekumhanya kwetambo refu. Izvi zvinoita kuti ive yakakodzera kushandiswa uko flow meter yakaiswa munzvimbo ine ruzha rweindasitiri kana kana chiratidzo chichifanira kutumirwa kure kure kuenda kukamuri rekudzora.

Zvinobuda muDigital

1. Kubuda kwePulse
   Miyero yekuyerera kwemvura ine simba rekufema inogadzira mapuroteni emagetsi. Huwandu hwemapuroteni pachikamu chenguva hunoenderana zvakananga nekufamba kwemvura. Semuenzaniso, muyero wekuyerera kwemvura unogona kuenzaniswa zvekuti parita yega yega yemvura inopfuura nepakati, inogadzira huwandu hwakatarwa hwemapuroteni, semuenzaniso mapuroteni zana parita. Nekuverenga mapuroteni aya munguva yakatarwa, huwandu hwese hwekuyerera kwemvura hunogona kuverengerwa. Kubuda kwemhepo kunowanzo shandiswa mumashandisirwo apo maseketi ekuverenga ari nyore anogona kuiswa zviri nyore, senge mune mamwe masisitimu ekutarisa kufamba kwemvura anodhura zvishoma kana mumamiriro ezvinhu apo mudziyo unogamuchira une kugona kwekuverenga kwemhepo.
2. Zvinobuda mukukurukurirana kweSerial
   Kune nzira dzakasiyana-siyana dzekutaurirana dzinoshandiswa pakubudisa flow meter. RS – 232, RS – 485, uye Modbus ndedzimwe dzinonyanya kufarirwa. NeRS – 232, data rinotumirwa zvakatevedzana pakati peflow meter nechinhu chinogashira, senge komputa kana programmable logic controller (PLC). RS – 485, kune rumwe rutivi, inogona kutsigira zvishandiso zvakawanda mubhazi rimwe chete uye ine daro refu rekutumira kana tichienzanisa neRS – 232. Modbus iprotocol yakagamuchirwa zvakanyanya inogona kushandiswa pamusoro peRS – 485 neEthernet. Kuburikidza neizvi serial communication outputs, flow meter inogona kutumira kwete chete current flow rate value asiwo rumwe ruzivo rwakadai se cumulative flow, status flags (zvinoratidza kana meter iri kushanda zvakanaka kana kuti yaona chikanganiso), uye calibration data. Ruzivo urwu rwakawanda runobatsira kune maitiro akaomarara emaindasitiri uko kunodiwa kutarisa nekudzora kwakazara.

Zvinobuda Pasina Waya

Mumakore achangopfuura, nekufambira mberi kwetekinoroji yewaya isina waya, ma flow metres ari kuwedzera kuve nehunyanzvi hwekuburitsa waya. Bluetooth, Wi-Fi, uye ZigBee ndiwo mamwe ema protocol ewaya asina waya anoshandiswa. Bluetooth yakakodzera kutaurirana kwenguva pfupi, inowanzoshandiswa kuma applications apo nyanzvi inoda kukurumidza kuwana data re flow meter achishandisa nharembozha, senge panguva yekuongorora kana kugadzirisa matambudziko panzvimbo. Wi-Fi inogonesa kutamisa data nekukurumidza munzvimbo yakakura, zvichibvumira data re flow meter kuti ribatanidzwe nyore nyore kune network yakakura ye plant uye riwanikwe kubva kunzvimbo dzakawanda. ZigBee, ine simba shoma rinoshandiswa uye kugona kwayo kuzvirapa, inobatsira kuma applications apo ma flow metres akawanda anofanira kubatanidzwa muindasitiri yakakura, uye kuchengetedza simba uye kutaurirana kwakavimbika kwakakosha.

Mukupedzisa, kubuda kwemita yekuyererainouya nenzira dzakasiyana-siyana, imwe neimwe ine zvayakanakira uye mashandisirwo ayo. Kusarudzwa kwerudzi rwezvinobuda zvinoenderana nezvinhu zvakaita serudzi rwechishandiso, daro rinodiwa nechiratidzo kuti chifambe, rudzi rwechishandiso chinogashira, uye kuoma kwehurongwa hwese umo flow meter yakabatanidzwa. Kunzwisisa sarudzo idzi dzakasiyana dzezvinobuda kwakakosha kuti mainjiniya nevashandisi vashandise data reflow meter zvinobudirira pakugadzirisa mashandiro eindasitiri.
