Ultrasonic flowmeter
Melemo ea acoustic flowmeter:
1. Tekanyo ea phallo e sa amaneng le motho
2. Ha ho tekanyo ea thibelo ea phallo, ha ho tahlehelo ea khatello.
3. Mokelikeli o se nang conductive o ka lekanyetsoa.
4. Phaephe e pharaletseng ea bophara bo fapaneng
5. Metsi, khase, oli, mefuta eohle ea mecha ea litaba e ka lekanyetsoa, sebaka sa eona sa kopo se pharaletse haholo.
Mathata a ultrasonic flowmeter:
1. Ho na le mefokolo e meng ea ho lekanya mecha ea litaba ea mocheso o phahameng.
2. Litlhoko tse phahameng tsa mocheso oa tšimo ea phallo.
3. Bolelele ba karolo e otlolohileng ea pipe e hlokahalang.
Electromagnetic flowmeter e na le melemo e mengata ho phallo ea mokelikeli mme e sebelisoa haholo liindastering tse fapaneng.
1Ha ho na likarolo tse thibelang phallo ho phala ea ho lekanya, ha ho tahlehelo ea khatello, 'me litlhoko tsa karolo e otlolohileng ea pipe e batla e le tlaase;
2 Ho nepahala ha tekanyo e phahameng, botsitso bo matla, bokhoni bo matla ba ho thibela thothomelo;
3 Tekanyo ha e amehe ke liphetoho tsa sekhahla sa mokelikeli, viscosity, mocheso, khatello le conductivity;
4 Ka mefuta e fapaneng ea li-electrode le likhetho tsa lesela, ho hanyetsa ka matla ho corrosion ea dielectric.
Ehlile, li-flowmeters tsa motlakase li na le mefokolo ea tsona:
1 Mokhoa oa ho lekanya o tlameha ho ba le conductivity e itseng (ka kakaretso e kholo ho feta 5us / cm), hape ho na le litlhoko tse itseng tsa ho lekanya lebelo la phallo ea pele (ka kakaretso e kholo ho feta 0.5m / s).
2 Mocheso oa mocheso oa mokhoa oa ho lekanya o lekanyelitsoe ke lisebelisoa tsa lesela, 'me phello ea tekanyo ea mocheso o phahameng ha e ntle.
3 Ha e khone ho lekanya khase, mouoane le mecha e meng ea litaba.
4 Haeba electrode ea ho lekanya e sebetsa nako e telele, ho ka 'na ha e-ba le sekhahla, se ka lekanyetsoang feela ka mor'a ho hloekisa.
5 Bakeng sa sehare se phahameng sa viscosity le seaplane se tiileng-mokelikeli oa mekhahlelo e 'meli, hoa hlokahala ho sebelisa phepelo ea maqhubu a phahameng, ho nepahala ho tlase ho tlase.
6 Ka lebaka la khaello ea molao-motheo oa sebopeho sa sensor, theko ea lihlahisoa tse kholo e phahame haholo, e bakang keketseho ea boleng ba sehlahisoa le theko.
7 Ka lebaka la mefokolo ea eona ea molao-motheo, mohala oa sensor o hloka ho matlafatsoa ho hlahisa matla a khoheli, 'me tšebeliso e lekantsoeng ea matla e batla e phahame, e sa lokelang ho fana ka matla a betri.
Papiso
1. Magnetic flowmeter ho nepahala ho feta ultrasonic flowmeter's.
2. Theko ea electromagnetic flowmeter e angoa ke bophara ba liphaephe, empa bakeng sa clamp ho ultrasonic flow meter, theko ea eona ha e amane le bophara ba pipe.
3. Magentic flow meter ha e thibele mofuta, ultrsonic flow meter ke boikhethelo bakeng sa clamp on, e ka fihlela methara ea phallo ea metsi e sa amaneng.
4. Ultrasonic flow meter e ka sebetsa le lino tse sa tsamaisang metsi, joalo ka metsi a hloekileng.Electromagnetic flow meter e khona ho lekanya lero la conductive.
5. Eletromagnetic flow meter ha e khone ho lekanya metsi a mocheso o phahameng haholo, empa ultrasonic flow meter e nepahetse ho metsi a mocheso o phahameng.
