1. E ntlafalitsoe bakeng sa Li-hydraulics tsa Parshall Flume

• Tšebelisano-'moho le moralo oa flume: Li-flume tsa Parshall li entsoe ho fetola lebelo la phallo hore e be keketseho ea boemo ba metsi e ka lekanngoang karolong e itseng ea "mmetso". Limithara tsa Ultrasonic li lekanya boemo bona ba bohlokoa ka nepo (hangata karolong e holimo ea 'metso kapa ea ho atamela ea flume) 'me li sebelisa mekhoa ea ho ntša flume ea Parshall e hlophisitsoeng esale pele ho bala sekhahla sa phallo.
• Diparamitha tsa flume tse kentsweng esale pele: Mehlala e mengata e kenyelletsa di-database tse kentsweng kahare tsa boholo bo tloaelehileng ba flume ya Parshall (mohlala, metso e 1-inch ho isa ho 50-foot) le di-coefficients tsa tsona tsa ho ntsha metsi tse tsamaellanang, ho fedisa ho kenngwa ha foromo ka letsoho le ho netefatsa ho latela maemo a haeteroliki (mohlala, ASTM D1941).

2. Tekanyo e sa Keneleng, e nang le Tšusumetso e Tlase

• Ho se kopane le phallo: Disensara tsa Ultrasonic di kentswe ka hodima karolo ya tekanyo ya flume ya Parshall (ha ho dikarolo tse kentsweng ka hare ho metsi), ho qoba ho sitiswa ke dipaterone tsa bohlokwa tsa phallo ya flume. Sena se bohlokwa hobane flume tsa Parshall di itshetlehile ka phallo e sa sitiswang ho boloka ho nepahala.
• Ha ho kotsi ea ho koaleha: Ho fapana le li-transducer tsa khatello kapa lipoleiti tsa weir, li-sensor tsa ultrasonic ha li angoe ke sediment, lithōle, kapa likaroloana tse phaphametseng tse tloaelehileng metsing a litšila, nosetso, kapa phallo ea indasteri—ke tsa bohlokoa bakeng sa lifomo tse sebelisoang lits'ebetsong tsa metsi a litšila.

3. Ho nepahala ho Hoholo Maemong a Bohlokoa a Phallo

• Ho lemoha boemo ka nepo: Li-flume tsa Parshall li hloka litekanyo tse nepahetseng tsa boemo libakeng tse itseng (mohlala, ntlha ea gauge e holimo) ho bala phallo. Li-sensor tsa Ultrasonic li fana ka ho nepahala ha boemo ba ± 0.1% ho isa ho ± 0.5% ea sekala se felletseng, esita le ka pherekano e nyane ea bokaholimo kapa ketso ea maqhubu ka har'a flume.
• Ho tshepahala ha palo ya phallo: E sebedisa equation ya Parshall flume ya ho ntsha metsi Q=C×Hn (moo Q = sekgahla sa phallo, H = hlooho e lekantsweng, C = coefficient, n = exponent), e kopantsweng le data ya boemo ba ultrasonic ho netefatsa hore diphetho di latelwa ke maemo a indasteri.

4. Ho ikamahanya le boholo le lits'ebetso tsa Parshall Flume

• E lumellana le boholo bohle bo tloaelehileng: E ​​sebetsa le li-flume tse nyane (tsa laboratori) ho isa ho tse kholo (tsa indasteri/temo), ho tloha ho li-flume tse nyane (molala oa lisenthimithara tse 1) ho isa ho li-flume tse kholo bakeng sa linoka kapa likanale (molala oa limithara tse 50).
• E sebetsana le mefuta e fapaneng ya phallo: Difomo tsa Parshall di etseditswe mefuta e itseng ya phallo (mohlala, 0.01 ho isa ho 300+ cfs), mme dimithara tsa ultrasonic di ikamahanya le mefuta ena ka ho lekanya diphetoho tse tsamaellanang tsa maemo, ho netefatsa ho nepahala ho pholletsa le phallo e tlase le e phahameng.

5. Tshebetso e Matla Tikolohong e Ikgethang ya Flume

• Ho hanela mathata a amanang le flume: Ts'ebetso e tsoetseng pele ea matšoao e hloekisa lerata le tsoang ho ho fafatsa, foam, kapa lipululana tsa moea—tse tloaelehileng ho li-flume tsa Parshall ka lebaka la ho potlaka ha phallo molaleng.
• Boemo ba leholimo le ho tšoarella ha tikoloho: Li-sensor tse nang le litekanyetso tsa IP65/IP66/IP67 li mamella pula, mongobo le maemo a feteletseng a mocheso, e leng tsa bohlokoa bakeng sa li-flume tsa kantle libakeng tsa temo, metsi a litšila, kapa metsi a pula.
• Moralo o thibelang tšitiso: O fokotsa ho baloa ha bohata ho tsoa letsatsing, ho bonahatsa mabota a flume, kapa lithōle tse phaphametseng holim'a metsi.

6. Ho kenya le ho lekanya ka bonolo

• Ho kenya ka mokhoa o nolofalitsoeng: Li-sensor li kenngoa ka holim'a ntlha ea gauge ea flume (hangata holim'a bracket kapa crossbar) ka mosebetsi o fokolang oa matsoho, ho qoba liphetoho sebopehong sa flume.
• Tekanyo e potlakileng: E ​​hlophisitsoe esale pele bakeng sa li-geometri tsa Parshall flume, e fokotsa nako ea ho seta. Basebelisi ba ka netefatsa ho nepahala ka ho hlahloba maemo habonolo ka sekhahla se tsebahalang sa phallo.

7. Data le Kopanyo ea Nako ea Sebele

• Tlhokomelo e tswelang pele: E fana ka sekgahla sa phallo ya nako ya sebele, boemo ba metsi, le data ya motsamao, e bontshwang sebakeng sa heno skrineng kapa e fetisetswang ho SCADA, PLCs, kapa dipolatefomo tsa maru ka Modbus, 4G/5G, Wi-Fi, kapa LoRa.
• Ho boloka data: Ho boloka data ea nalane ea phallo (mohlala, karolelano ea hora/letsatsi, phallo ea tlhoro) bakeng sa tlaleho ea ho latela melao, kemiso ea nosetso, kapa ntlafatso ea kalafo ea metsi a litšila.
• Tšoso: Litemoso tse ka lokisoang bakeng sa maemo a holimo/a tlase (a bontšang ho thijoa ha flume kapa ho phalla ha metsi) kapa mathata a sensor, a nolofalletsang tlhokomelo e potlakileng.

8. Tlhokomelo e Tlase le Bophelo bo Bolelele

• Ha ho na likarolo tse sisinyehang: E ​​felisa ho tsofala ha likarolo tsa mechini, e fokotsa nako ea ho sebetsa. Tlhokomelo ea kamehla e lekanyelitsoe ho hloekiseng sensor nako le nako (ho tlosa lerōle kapa marang-rang a likho) le ho hlahloba litekanyetso.
• Kaho e tšoarellang: Li-sensor le li-transmitter li hahiloe ho mamella maemo a thata, ho netefatsa bophelo bo bolelele ba ts'ebeletso esita le libakeng tsa kantle kapa tsa indasteri.

9. E bolokang tjhelete bakeng sa Ditsamaiso tsa Flume

• Litšenyehelo tsohle tsa beng li tlase ha li bapisoa le limithara tse kenang: Ha ho hlokahale li-sensor tse qoelitsoeng (tse hlokang ho nkeloa sebaka khafetsa ka lebaka la mafome kapa ho koaleha) kapa liphetoho tsa flume.
• E fokotsa litšenyehelo tsa basebetsi: Ho kenya habonolo le tlhokomelo e fokolang ho fokotsa litšenyehelo tsa ts'ebetso ha nako e ntse e ea.

10. Ho latela Melao

• E fihlela maemo a machaba bakeng sa litekanyo tsa flume tsa Parshall (mohlala, ASTM D1941, litataiso tsa ISO) le litlhoko tsa taolo bakeng sa tsamaiso ea mehloli ea metsi, tlhokomelo ea tikoloho, le tlaleho ea ho ntša metsi indastering.
