Umvavanyi weVolumu
Isishwankathelo seMveliso
Umlungisi wevolumu usetyenziselwa ikakhulu ukufumana ubushushu, uxinzelelo, ukuhamba kunye neminye imiqondiso yerhasi kwi-intanethi. Ikwenza ulungiso oluzenzekelayo lwento yoxinzelelo kunye nokulungiswa kokuhamba okuzenzekelayo, kwaye iguqula ivolumu yemeko yokusebenza ibe ngumthamo welizwe eliqhelekileyo.
IIMBONAKALO
1 Xa inkqubo yemodyuli yempazamo, iya kwenza umxholo wempazamo kwaye iqale indlela ehambelanayo.
2.Prompt / alarm / irekhodi kwaye uqale ehambelanayo indlela phantsi uhlaselo ngemagneti enamandla.
Isinxibelelanisi soxinzelelo oluninzi, esinokutshatiswa kunye noxinzelelo lwedijithali / isivamvo soxinzelelo; kunye nobushushu bunokutshatiswa ne-PT100 okanye i-PT1000.
Ukuzivavanya ngokwakho ngesiphoso soxinzelelo kunye neqondo lobushushu emva koko ubonise isikrini seLCD ngokuthe ngqo; emva koxinzelelo okanye isivamvo sobushushu sisempazamo, i-flowzier yokuhamba iya kulungisa uxinzelelo okanye ixabiso lobushushu ngokwexabiso elibekiweyo lokukhusela idatha ekonakaleni.
5.Imisebenzi yokubonisa ngaphezulu kokuhamba kokuhamba komsebenzi, ngaphezulu komda wokubonisa ukusebenzisa uxinzelelo kunye nokurekhoda okulungeleyo ukuqonda ukusetyenziswa kweendaba;
Iseti yebhetri ye-lithium ingasetyenziswa ngokuqhubekekayo ngaphezulu kweminyaka emi-3, kwaye inemisebenzi yokukhutshelwa kwamandla ombane ophantsi webhetri kunye nokuvalwa kwevalve kwi-alamu, efanelekileyo ngakumbi ukuxhasa ukusetyenziswa kwenkqubo yolawulo lwekhadi le-IC.
Umsebenzi wexesha lokubonisa kunye nokugcinwa kwedatha yexesha lokwenyani unokuqinisekisa ukuba idatha yangaphakathi ayizukulahleka kwaye inokugcinwa ngokusisigxina nokuba injani imeko.
Ukukhutshwa kwemiqondiso emininzi: I-4-20mA yangoku isignali ye-analog / imeko yendlela yokubetha / ikhadi le-IC elinophawu lomgangatho oqhelekileyo kunye ne-RS485 protocol yokunxibelelana; Ngokweemfuno zomsebenzisi, imisebenzi yenethiwekhi ye-GPRS inokubonelelwa ngexabiso eliphantsi, ukuhambisa idatha ngaphandle kwamacingo ngexesha elifanelekileyo; imisebenzi ye-IOT egciniweyo yokuqonda inokubona imisebenzi ye-IOT.
Imo yokusebenza ye-9 inokutshintshwa ngokuzenzekelayo: ibhetri-inikwe amandla, inkqubo yocingo ezimbini, inkqubo yocingo ezintathu

Inkcazo yokusebenza kombane
2.1Ukusebenza kwamandla：
- Ukunikezelwa kwamandla angaphandle: + 12 - 24VDC ± 15%, i-ripple <5%, ifanelekile kwi-4 - 20mA, ukuphuma kwe-pulse, ukukhutshwa kwe-alarm, i-RS-485 yokunxibelelana kunye nokunye.
- Unikezelo lwamandla lwangaphakathi: Iseti yebhetri ye-lithium engu-3.6V, xa ombane engaphantsi kune-3.0V, kubonakala ukungabonakali kwamandla.
2.2 Ukusetyenziswa kwamandla kwemitha yonke：
A. Amandla angaphandle: <2W;
B. Amandla angaphakathi: amandla aphakathi: ≤1mW, iseti yebhetri ye-lithium inokusetyenziswa ngokuqhubekayo ngaphezulu kweminyaka emi-3, xa imitha ikwindawo yokulala, ukusetyenziswa kwamandla: ≤0.3mW.
2.3 Imowudi yokukhupha imveliso：
Imeko yokusebenza kwe-pulse signal (FOUT): ethe yafunyanwa ngokuthe ngqo yintshukumo yokuhamba yodwa ngokusebenzisa i-optocoupler bodwa yandisa imveliso, inqanaba eliphezulu: ≥20V, inqanaba eliphantsi: ≤1V
B.Umqondiso wokubetha olinganayo (H / L): ukukhutshwa okuphuculweyo kwitekhnoloji ye-optocoupler yokuzahlula, uluhlu oluphezulu: ≥20V, uluhlu olusezantsi: ≤1V. Ukubetha kweyunithi kubonisa uluhlu lwevolumu esemgangathweni enokuseta: 0.01 m³ / 0.1 m3m³ / 1m3m³ / 10m³, Upper and lower limit alarm alarm (H / L): ukubekwa ecaleni kwe-photoelectric, i-alamu ephezulu kunye nezantsi, i-voltage esebenzayo: + 12V - + I-24V, owona mthwalo uphakamileyo ungama-50mA.
2.4 RS ukuya kuma-485 unxibelelwano (ipheukwahlulwa kwe-hotoelectric)：
Ngonxibelelwano lwe-RS-485, inokunxibelelana ngqo nekhompyuter ephezulu okanye isixhobo. Ingadlulisela kude ubushushu, uxinzelelo, ukuhamba kwangoko, ivolumu esemgangathweni iyonke kunye nezinye iiparameter ezinxulumene nesixhobo somlinganiso ophakathi, ikhowudi yempazamo, inqanaba lokusebenza, amandla ebhetri kunye nolunye ulwazi lwexesha langempela.
2.5 4-20mA umqondiso wangoku (ipheukwahlulwa kwe-hotoelectric)：
Ngokulingana nokuhamba kwevolumu esemgangathweni, i-4mA iyahambelana ne-0m³ / h, i-20 mA iyahambelana nokuhamba okuphezulu komthamo (ixabiso linokumiselwa kwimenyu yenqanaba lokuqala), inkqubo: inkqubo yocingo ezimbini okanye inkqubo yocingo ezintathu, imitha yokuhamba inokuchonga ngokuzenzekelayo kwaye ikhuphe ngokuchanekileyo ngokwemodyuli efakiweyo yangoku.
2.6 Ukulawulwa kwemveliso yolawulo：
A. Ikhadi le-IC uphawu lwevolumu esemgangathweni (IC_out): Ngohlobo lokuphuma komtya oprinta umtya, ububanzi be-pulse yi-50ms, 100ms, 500ms, i-pulse amplitude imalunga ne-3V, inqanaba eliqhelekileyo linokuseta, umgama wokuhambisa: ≤50m Ukubetha kwentliziyo nganye kubonisa: 0.01m³, 0.1m³, 1m³, 10m³, Ilungele ukusetyenziswa kunye neenkqubo zekhadi le-IC;
Ukuveliswa kwamandla ombane webhetri (i-terminal ye-BC, i-alamu yebhetri ephantsi ye-alamu): imveliso evulekileyo yokuqokelela, ubungakanani: ≥2.8V, uxhathiso lomthwalo: ≥100kΩ;
C. Ukuveliswa kwe-alamu yebhetri yokungasebenzi (i-BL yesiphelo, ibhetri esezantsi ye-alamu yevolthi ephantsi): imveliso evulekileyo yokuqokelela, ubungakanani: ≥2.8V, uxhathiso lomthwalo: ≥100kΩ
