1. Electromagnetic Flowmeters (EMFs)

Cov txheej txheem kev lag luam rau kev siv dej khib nyiab hauv nroog thiab kev lag luam, EMFs siv Faraday Txoj Cai ntawm electromagnetic induction los ntsuas cov dej ntws hauv cov dej tsis muaj qhov txav mus los.

• Qhov tseeb: ± 0.5% ntawm kev nyeem ntawv lossis zoo dua
• Yam tsawg kawg nkaus conductivity: 5 μS / cm
• Qhov zoo tshaj plaws rau: Sludge, dej phwj nyoos, thiab kev ntsuas cov dej ntws tawm

2. Qhib Channel Flowmeters

Rau cov ntawv thov uas tsis muaj cov kav dej txuas, cov tshuab no muab cov khoom siv tseem ceeb (flumes / weirs) nrog cov ntsuas ntsuas ntsuas los ntsuas cov nqi ntws.

• Ntau hom: Parshall flumes, V-notch weirs
• Qhov tseeb: ± 2-5% nyob ntawm kev teeb tsa
• Qhov zoo tshaj plaws rau: Stormwater, oxidation ditches, thiab gravity-fed systems

1. pH/ORP Meters

Qhov tseem ceeb rau kev tswj cov dej ntws tawm hauv cov kev cai txwv (feem ntau pH 6-9) thiab saib xyuas oxidation-txo cov peev txheej hauv kev kho mob.

• Electrode lub neej: 6-12 lub hlis hauv dej khib nyiab
• Tsis siv neeg tu tshuab pom zoo rau kev tiv thaiv fouling
• ORP ntau yam: -2000 txog +2000 mV rau kev saib xyuas cov dej khib nyiab tiav

2. Conductivity Meters

Ntsuas tag nrho cov yaj yaj (TDS) thiab cov ntsiab lus ionic, muab kev tawm tswv yim tam sim ntawm cov tshuaj lom neeg thiab cov ntsev hauv cov dej khib nyiab.

3. Dissolved Oxygen (DO) Meters

Qhov tseem ceeb rau cov txheej txheem kho aerobic lom, nrog rau cov khoom siv kho qhov muag tam sim no ua tau zoo dua cov txheej txheem ib txwm siv hauv cov dej khib nyiab.

• Optical sensor zoo: Tsis muaj daim nyias nyias, kev saib xyuas tsawg
• Feem ntau: 0-20 mg / L (0-200% saturation)
• Qhov tseeb: ± 0.1 mg / L rau kev tswj cov txheej txheem

4. COD Analyzers

Chemical Oxygen Demand ntsuas tseem yog tus qauv rau kev ntsuas cov pa phem hauv cov khoom, nrog cov kws tshuaj ntsuam niaj hnub muab cov txiaj ntsig hauv 2 teev piv rau cov qauv 4-teev.

5. Tag nrho Phosphorus (TP) Analyzers

Advanced colorimetric txoj kev siv molybdenum-antimony reagents muab kev kuaj pom cov kev txwv qis dua 0.01 mg / L, qhov tseem ceeb rau kev ua kom tau raws li qhov yuav tsum tau tshem tawm cov zaub mov nruj.

6. Ammonia Nitrogen (NH₃-N) Analyzers

Niaj hnub nimno salicylic acid photometry txoj kev tshem tawm cov mercury thaum tswj ± 2% raug rau ammonia xyuas nyob rau hauv influent, txheej txheem tswj, thiab effluent ntws.

1. Submersible Theem Transmitters

Ventilated los yog ceramic sensors muab kev ntsuas qib txhim khu kev qha hauv cov ntawv thov dej huv, nrog cov titanium vaj tsev nyob rau qhov chaw corrosive.

• Qhov tseeb: ± 0.25% FS
• Tsis pom zoo rau: Sludge pam vov los yog roj-laden khib nyiab

2. Ultrasonic Qib Sensors

Cov tshuaj tsis tiv tauj rau kev saib xyuas cov dej khib nyiab dav dav, nrog rau qhov kub thiab txias rau kev teeb tsa sab nraum zoov. Yuav tsum tau 30 ° beam kaum sab xis rau kev ua haujlwm zoo hauv cov tso tsheb hlau luam thiab cov channel.

3. Radar Qib Sensors

26 GHz lossis 80 GHz radar thev naus laus zis nkag mus ua npuas dej, chav ua haujlwm, thiab qhov chaw turbulence, muab cov kev nyeem ntawv qib siab tshaj plaws hauv cov dej khib nyiab nyuaj.

• Qhov tseeb: ± 3mm lossis 0.1% ntawm ntau yam
