2. Ultrasonic Flow Meters
2.1 Molao-motheo oa ho Sebetsa
Mehato ea lebelo la ho phalla ka ho sebelisa phapang ea nako ea ho tsamaea (nako ea ho fofa) kapa phello ea Doppler. Mefuta e 'meli ea sehlooho:
- Clamp-on (Ha e hlasele): Ho kenya habonolo
- Insertion: E loketse liphaephe tse kholo
2.2 Likarolo tsa Setegeniki
- Mecha ea litaba e loketseng: Liquids le likhase (mefuta e ikhethileng e fumanehang), e tšehetsa phallo e le 'ngoe / mekhahlelo e mengata
- Melemo:
- Ha ho na khatello e theohang, e loketseng maro a phahameng a viscosity (mohlala, oli e tala)
- Mekhahlelo e pharaletseng (0.01–25 m/s), ho nepahala ho fihla ho ±0.5%
- E ka kenngoa inthaneteng, tlhokomelo e tlaase
- Meeli:
- E angoa ke thepa ea liphaephe (mohlala, tšepe e entsoeng ka tšepe e ka fokotsa matšoao) le homogeneity ea mokelikeli
- Litekanyo tse nepahetseng haholo li hloka phallo e tsitsitseng (qoba moferefere)
2.3 Likopo tse Tloaelehileng
- Oli & Gas: Tlhokomelo ea lipeipi tsa sebaka se selelele
- HVAC Systems: Tekanyo ea matla bakeng sa metsi a batang / a futhumatsang
- Tlhokomelo ea Tikoloho: Tekanyo ea phallo ea noka/mokelikeli (mefuta e nkehang)
3. Limithara Tsa Phallo ea Khase
3.1 Mefuta le Likarolo tse ka Sehloohong
| Mofuta | Molao-motheo | Likhase tse Loketseng | Melemo | Mefokolo |
|---|---|---|---|---|
| Mocheso oa 'Misa | Ho qhala mocheso | Likhase tse hloekileng (moea, N₂) | Phallo e tobileng ea boima, ha ho matšeliso a mocheso / khatello | Ha e lokele likhase tse mongobo/lerole |
| Pherekano | Seterata sa Kármán vortex | Mouoane, khase ea tlhaho | Ho hanyetsa mocheso o phahameng/khatello | Kutlo e tlase ha phallo e tlase |
| Turbine | Ho potoloha ha rotor | Khase ea tlhaho, LPG | Ho nepahala ho phahameng (±0.5%–±1%) | E hloka tlhokomelo ea ho jara |

4. Litaelo tsa Papiso le Khetho
| Paramethara | Motlakase | Lisebelisoa tsa Ultrasonic | Khase (Mohlala oa Thermal) |
|---|---|---|---|
| Mecha ea litaba e loketseng | Mekelikeli e tsamaisang | Mekelikeli/khase | Likhase |
| Ho nepahala | ±0.2%–0.5% | ±0.5%–1% | ±1%–2% |
| Tahlehelo ea Khatello | Ha ho letho | Ha ho letho | Nyenyane |
| Ho kenya | Pipe e felletseng, e thellang | E hloka ho matha ka kotloloho | Qoba ho thothomela |
| Litšenyehelo | Mahareng-hodimo | Mahareng-hodimo | Tlase-bohareng |
Lintlha tsa Khetho:
- Tekanyo ea Mokelikeli: Electromagnetic bakeng sa maro a conductive; ultrasonic bakeng sa mecha ea litaba e sa conductive / e senyang.
- Tekanyo ea Khase: Thermal bakeng sa likhase tse hloekileng; vortex bakeng sa mouoane; turbine bakeng sa phetisetso ea litlamong.
- Litlhoko tse Khethehileng: Lisebelisoa tsa bohloeki li hloka meralo e se nang sebaka; mecha ea phatlalatso ea mocheso o phahameng o hloka lisebelisoa tse thibelang mocheso.
5. Liqeto le Mekhoa ea Kamoso
- Limithara tsa phallo ea motlakase li laola liindasteri tsa lik'hemik'hale / tsa metsi, ka tsoelo-pele ea nakong e tlang ea tekanyo ea mokelikeli o tlase oa conductivity (mohlala, metsi a ultrapure).
- Methapo ea phallo ea Ultrasonic e ntse e hola ka taolo e bohlale ea metsi / matla ka lebaka la melemo e sa amaneng le batho.
- Limithara tsa phallo ea khase li ntse li tsoela pele ho ea ho kopanyo ea liparamente tse ngata (mohlala, matšeliso a mocheso / khatello + tlhahlobo ea sebopeho) bakeng sa ho nepahala ho holimo.
- Sete e felletseng ea li-server le software e se nang mohala, e tšehetsa RS485 GPRS /4g/WIFI/LORA/LORAWANHo fumana lintlha tse ling tsa "flow meter",
