Uhlolojikelele Lomkhiqizo
Isilungisi sevolumu sisetshenziswa kakhulu ukuthola izinga lokushisa, ingcindezi, ukugeleza nezinye izimpawu zegesi ku-inthanethi.Iphinde yenza ukulungiswa okuzenzakalelayo kwesici sokucindezela kanye nokulungiswa okuzenzakalelayo kokugeleza, futhi iguqule ivolumu yesimo sokusebenza ibe umthamo wesimo esijwayelekile.
IZICI
1.Uma imojuli yesistimu inephutha, izokwazisa okuqukethwe kwephutha futhi iqale indlela ehambisanayo.
2.Sheshisa/i-alamu/rekhoda futhi uqale indlela ehambisanayo ngaphansi kokuhlasela kukazibuthe oqinile.
3.Isixhumi esibonakalayo sokucindezela okuningi, esingamataniswa nenzwa yokucindezela kwedijithali/inzwa yokucindezela; futhi izinga lokushisa lingafaniswa ne-PT100 noma i-PT1000.
4.Ukuzihlola ngokwakho ngephutha lokucindezela kanye nenzwa yokushisa bese kuboniswa kusikrini se-LCD ngqo;ngemva kokuba ingcindezi noma inzwa yezinga lokushisa inephutha, i-flow totalzier izolungisa ingcindezi noma inani lokushisa ngokwenani elimisiwe ukuze kuvikelwe idatha ekonakalisweni.
5.Imisebenzi yokubonisa okungaphezu komkhawulo wokugeleza kokusebenza, ukubonisa okungaphezu komkhawulo wokusebenzisa ingcindezi nokuqopha okulula ukuqonda ukusetshenziswa kwangempela kwemidiya;
I-6.Isethi yebhethri ye-lithium ingasetshenziswa ngokuqhubekayo iminyaka engaphezu kwengu-3, futhi inemisebenzi yokuphuma kwe-voltage ephansi yebhethri ne-valve evala i-alamu, efaneleka kakhulu ukusekela ukusetshenziswa nesistimu yokuphatha ikhadi le-IC.
7.Umsebenzi wokuboniswa kwesikhathi kanye nokugcinwa kwedatha yesikhathi sangempela kungaqinisekisa ukuthi idatha yangaphakathi ngeke ilahleke futhi ingalondolozwa unomphela kungakhathaliseki ukuthi isimo sinjani.
I-8.Izimpawu zokuphuma eziningi: I-4-20mA yamanje isignali ye-analog ejwayelekile / isimo sokusebenza isignali ye-pulse / ikhadi le-IC elinesignali yevolumu evamile kanye ne-protocol yokuxhumana ye-RS485;Ngokwezidingo zomsebenzisi, imisebenzi yenethiwekhi ye-GPRS ingahlinzekwa ukuze kutholakale ukuhanjiswa kwedatha okungenazintambo ebiza kancane, yamabanga amade ngesikhathi sangempela;I-interface ye-IOT egciniwe ingakwazi ukubona imisebenzi ye-IOT.
I-9.Imodi yokusebenza ingashintshwa ngokuzenzakalelayo: ibhethri-powered, isistimu yezintambo ezimbili, isistimu yezintambo ezintathu

Inkomba yokusebenza kukagesi
2.1Amandla okusebenza:
- Ukunikezwa kwamandla kwangaphandle: + 12 - 24VDC ± 15%, ripple <5%, ifaneleka ku-4 - 20mA okukhiphayo, ukuphuma kwe-pulse, okukhipha i-alamu, ukuphuma kwe-RS-485 kokuxhumana nokunye.
- Ukunikezwa kwamandla kwangaphakathi: Isethi yebhethri ye-lithium engu-3.6V, lapho i-voltage ingaphansi kuka-3.0V, kuvela inkomba ye-undervoltage.
2.2Ukusetshenziswa kwamandla kwemitha yonke:
A. Amandla angaphandle:<2W;
B. Amandla angaphakathi: amandla aphakathi: ≤1mW, isethi yebhethri ye-lithium ingasetshenziswa ngokuqhubekayo iminyaka engaphezu kwengu-3, lapho imitha isesimweni sokulala, ukusetshenziswa kwamandla: ≤0.3mW.
2.3Imodi yokuphuma kwe-Pulse:
A. I-Operation condition pulse signal (FOUT): etholwe ngokuqondile inzwa yokugeleza nge-optocoupler isolation ikhulisa futhi ikhiphe, izinga eliphezulu: ≥20V, ileveli ephansi: ≤1V
B. Isignali ye-pulse elinganayo (H/L): okukhiphayo okukhulisiwe ngobuchwepheshe bokuhlukaniswa kwe-optocoupler, ibanga lezinga eliphezulu: ≥20V，ububanzi bezinga eliphansi: ≤1V.I-unit pulse imele ububanzi bevolumu obujwayelekile obungasethwa: 0.01 m³/0.1 m3m³/1m3m³/10m³; Amasiginali we-alamu yomkhawulo ophezulu naphansi (H/L):ukuhlukaniswa kwesithombe, i-alamu yezinga eliphezulu neliphansi, i-voltage esebenzayo:+ 12V - + 24V, umthamo omkhulu wamanje ongu-50mA.
2.4 RS-485ukuxhumana (pukuhlukaniswa kwe-hotoelectric):
Ngesixhumi esibonakalayo se-RS-485, ingaxhunywa ngokuqondile nekhompyutha ephezulu noma insimbi.Ingakwazi ukudlulisa ukude izinga lokushisa, ingcindezi, ukugeleza okusheshayo, isamba sevolumu ejwayelekile nezinye izinhlaka ezihlobene zethuluzi eliphakathi nendawo, ikhodi yephutha, isimo sokusebenza, umthamo webhethri kanye nenye idatha yesikhathi sangempela.
2.5 4-20mAisignali yamanje (isibukuhlukaniswa kwe-hotoelectric):
Ngokuhambisana nokugeleza kwevolumu evamile, i-4mA ihambisana no-0m³/h, 20 mA ihambisana nokugeleza kwevolumu evamile (inani lingasethwa kumenyu yezinga lokuqala), isistimu: isistimu yezintambo ezimbili noma isistimu yezintambo ezintathu, imitha yokugeleza ingakwazi ukukhomba ngokuzenzakalelayo futhi ikhiphe ngendlela efanele ngokusho kwemojula yamanje efakiwe.
2.6Lawula ukuphuma kwesignali:
Isignali yevolumu ejwayelekile yekhadi le-IC (IC_out): Ngendlela yokuphuma kwentambo yesiginali ye-pulse, ububanzi be-pulse bungama-50ms, 100ms, 500ms, i-pulse amplitude imayelana ne-3V, izinga elijwayelekile lingasethwa, ibanga lokudlulisela:≤50m , i-pulse ngayinye imele: 0.01m³, 0.1m³, 1m³, 10m³, Ifanele ukusetshenziswa namasistimu ekhadi le-IC;
