5- Instruments and measurements

-Sensors and transmitters selection, calibration
Ultrasonic level – Electromagnetic flow- Ultrasonic flow- dissolved oxygen
-PH sensors- MLSS Mixed liquor suspended solids- Turbidity – toxicity- pressure differential –ORP sensors- residual chlorination- H2s sensors- – Vacuum Pressure switch.
Switches (level –pressure- torque-leak)
Temperature detectors (PTCs – RTDs – thermocouples)
