GreenPrima ProLe v600 Open-Channel Flowmeter

Overview

The GreenPrima ProLe v600 is a non-contact ultrasonic open-channel flowmeter engineered for high-reliability, long-term deployment in municipal and industrial wastewater, potable water distribution, irrigation infrastructure, and chemical effluent monitoring applications. Unlike submersible or float-based level sensors, the ProLe v600 employs time-of-flight ultrasonic distance measurement to determine liquid surface height above the channel bed—eliminating errors induced by air temperature gradients, humidity fluctuations, or density variations that commonly degrade conventional stilling-well or pressure transducer-based level readings. By integrating real-time level data with pre-configured hydraulic equations (e.g., ISO 4359, ASTM D1941, and ISO 1438 standards), the device computes instantaneous velocity profiles and volumetric flow rates across standardized flumes (e.g., Palmer-Bowlus, Parshall, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-Bowlus, Palmer-B……
