Overview
The GreenPrima PROLEV600 Ultrasonic Open-Channel Flowmeter is an engineered solution for continuous, non-invasive flow measurement in gravity-fed open channels—primarily deployed in municipal wastewater treatment plants, drinking water distribution networks, irrigation canals, combined sewer overflows (CSOs), and industrial effluent monitoring applications. It operates on the principle of ultrasonic time-of-flight level sensing: a high-frequency transducer emits and receives acoustic pulses across the channel, measuring the transit time between emission and echo return to calculate liquid level with sub-millimetric resolution. This level data is then processed using the velocity-area method, incorporating pre-programmed hydraulic algorithms for standardized flumes (e.g., Parshall, Palmer-Bowlus, Palmer-Bowlus) and weirs (e.g., V-notch, Cipoletti), as well as user-defined cross-sectional geometries. Unlike pressure-based or float-type level sensors, the PROLEV600 eliminates errors induced by air temperature gradients, humidity, and vapor condensation—common sources of drift in submerged or vented systems. Its design adheres to fundamental metrological principles outlined in ISO 4064-1 (water meters) and ASTM D5389 (open-channel flow measurement), ensuring traceable performance under variable environmental loads.
Key Features
- Non-contact ultrasonic level sensing ensures immunity to fouling, corrosion, and sediment accumulation typical in raw sewage and stormwater environments
- High-stability transducer with temperature-compensated timing circuitry maintains ±0.2% full-scale accuracy across −30 °C to +70 °C ambient operating range
- Integrated dual-mode output: isolated 4–20 mA analog signal (HART-compatible wiring) and Modbus RTU over RS-485 for seamless integration into SCADA, DCS, and PLC architectures
- Backlit monochrome LCD display with tactile membrane keypad enables local configuration, real-time diagnostics, and manual calibration without external tools
- Ruggedized housing constructed from UV-stabilized polycarbonate (PC) and polypropylene (PP) blend meets IP67 ingress protection and withstands prolonged exposure to H2S, chlorine, and organic solvents
