Wastewater Effluent Flow Meter
- Nivelco EasyTREK Ultrasonic Flow Meter
- Nivelco MultiCONT Process Controller / Display
- 90 Degree V-notch Weir
- Wastewater Effluent Sampler
How it Works:
Wastewater flow is measured after final treatment and before leaving the plant into the receiving water. V-notch weirs are used as a primary flow device to generate head. The ultrasonic level transmitter and flow meter measures the level of water above the crest or bottom of the v-notch weir. The ultrasonic level transmitter is located at a point back from the weir plate that is three to five times the maximum head of the weir, also known as Hmax. The water in the weir pool located below the ultrasonic level flow meter must be at least 2-3 times the Hmax.
The measured water level above the crest or crest elevation is then used by the flow meter to calculate the flow based upon a standard v-notch weir flow formula. The ultrasonic flowmeter then provides a flow proportional 4-20 mA output signal to the wastewater plant SCADA system, UV disinfection system, Effluent Wastewater Sampler and monitoring systems. The water flows over the crest and forms the nappe before entering the downstream pool.
