Kubuda kweUltrasonic Flowmeters

1. Zviratidzo zveAnalog Output

Mabhatiri e analog anonyanya kuzivikanwa kubva kuma ultrasonic flowmetersmasaini emagetsi e4 - 20 mA uye masaini emagetsi e0 - 5V/0 - 10V. Chinotenderera chemagetsi che4 - 20 mA chakavimbika zvikuru uye hachipindirwi nemagetsi, zvichiita kuti chive chakakodzera ma transmissions ari kure mumaindasitiri. 4 mA current inoenderana ne zero flow, nepo 20 mA ichiratidza mwero wepamusoro wekuyerera kwemagetsi unoshandiswa nechiyero cheflowmeterinoongororwa. Semuenzaniso, mufekitori yekuchenesa mvura, chiratidzo ichi che4 - 20 mA chinogona kuiswa zvakananga mu programmable logic controller (PLC) kuti chidzore kuyerera kwemvura kuburikidza nenzira dzakasiyana dzekurapa.

Zviratidzo zvemagetsi, zvakaita se0 - 5V kana 0 - 10V, zvinoshandiswawo. Zviri nyore kushandisa zvishandiso zvemagetsi zvakaita semakadhi ekuwana data. Zvisinei, zvinogona kukanganiswa zvakanyanya kana tambo dzakareba dzichishandiswa. Zviratidzo izvi zvinowanzo shandiswa mukuyedza kwakavakirwa murabhoritari kana mumasisitimu ane daro riri pakati pechiyero cheflowmeteruye mudziyo unogamuchira hausi mupfupi.

2. Zvinobuda muDigital

2.1 Kubuda kwePulse

Mazhinji ma ultrasonic flowmeters anopa pulse output. Pulse yega yega inomiririra huwandu hwakati hwemvura inopfuura nemu flowmeter. Frequency yema pulses inoenderana zvakananga ne flow rate. Semuenzaniso, kana pulse imwe chete ikagadzirwa pa 100 milliliters yega yega ye fluid, flow rate yakakwira ichaita kuti pulse frequency yakakwira. Rudzi urwu rwe output runobatsira kuma applications uko kunodiwa kuverenga nyore kwe fluid volume, senge muma dosing systems madiki kana mune mamwe ma applications anodhura zvishoma ekutarisa flow.

2.2 Zvinobuda muKutaurirana kweSerial

Maitiro ekutaurirana akadai seRS - 485, RS - 232, uye Modbus ndiwo ma "digital outputs" akajairika. RS - 485 inobvumira kutaurirana kwe "multi-drop", zvichiita kuti ma "flowmeters" akawanda abatanidzwe kune "single controller" mubhazi rimwe chete. Ine daro refu rekutaurirana uye inogona kubata kutumira data nekukurumidza. Modbus, kune rumwe rutivi, inzira inoshandiswa zvakanyanya mumunda we "industrial automation". Inopa nzira yakajairika yekutaurirana data pakati pemidziyo yakasiyana. NeModbus,ma ultrasonic flowmetersinogona kutumira ruzivo rwakadzama rwakadai sehuwandu hwekuyerera kwemvura, huwandu hwese hwemvura, uye mamiriro emudziyo kune system yekudzora yepakati. Izvi zvinobatsira zvikuru mumafekitori makuru emaindasitiri uko kunofanirwa kuongororwa uye kudzorwa kwematanho akawanda ekuyerera kwemvura panguva chaiyo.

3. Kuenzanisa Kubuda uye Kururama

Kururama kwezvinobuda kubva kuultrasonic flowmeterzvinoenderana nekuongororwa kwakakodzera. Vagadziri vanowanzopa zvinhu zvekugadzirisa zvinoshandiswa kushandura zviratidzo zvekubuda zvisina kujeka (zvakadai sekuyera nguva yekubhururuka kwe ultrasonic flowmeters) kuita mwero wekuyerera unoreva kana huwandu hwevhoriyamu. Kuongororwa nguva dzose kwekugadzirisa kwakakosha kuve nechokwadi chekuti kubuda kunoramba kwakarurama nekufamba kwenguva. Zvinhu zvakaita sekuchinja kwehunhu hwemvura (senge viscosity kana tembiricha), kupera kwezvikamu zve flowmeter, uye mamiriro ekunze zvinogona kukanganisa kururama kwekubuda. Nekugadzirisa nguva nenguva flowmeter nekugadzirisa kubuda zvichibva pamhedzisiro yekuongororwa, data rekuyera kuyerera rakavimbika uye rakarurama rinogona kuwanikwa.

Mukupedzisa, zvakabuda kubvama ultrasonic flowmetersdzakasiyana-siyana uye dzinoshanda zvakasiyana mumabasa akasiyana-siyana. Ingave chiratidzo cheanalog chekudzora zviri nyore, kubuda kwepulse kwekuverenga vhoriyamu yekutanga, kana kubuda kwedhijitari serial kwekubatanidza data rakaoma, kunzwisisa kubuda uku kwakakosha pakushandisa tekinoroji ye ultrasonic flowmeter zvakanyanya.
