Measurement and Automatic Control Techniques
Measurement technique:
- Temperature sensors
- Level probes (ultrasonic, pressure and capacitive)
- pH measuring instruments
- O2 measuring instruments
- Dried matter measuring instruments
- Quantity measuring (IDM, double flow velocity sensors in the sewer)
- Gas sensors
- On-line measuring instruments (NO3-N, NH4-N, PO4-P)
