ALSONIC-RAVM SC
SmartMeasurement’s ALSONIC RAVM-MC is a combined radar velocity and level transducer used with our multi-channel controller (MC) which may include a number of radar velocity (VS) transducers providing a true non-intrusive approach to open channel area velocity measurement in channels having widths of up to 500 m. The Alsonic-RAVM-MC can also be configured with up to 32 standalone radar velocity (VS) and/or velocity/level (VL) transducers in series in order to accurately profile large open channel systems (please see diagram on page 2.) The system is designed for continuous non-intrusive flow measurement of rivers, streams, municipal wastewater, and stormwater channels. Users can also install a number of radar velocity (VS) transducers in combination with our radar level transducers (RL) which provide the same measurement as the combined VL/VS system. For channel widths of up to 10 meters, a cost-effective single-channel system (SC) is recommended.
The ALSONIC RAVM-MC requires a multichannel controller with configuration software and MODBUS output to be configured in the control room on a standalone PC. MODBUS data includes flow, velocity,and height as well as sensor diagnostics. In applications where users want to install another level measurement technology (other than radar), either a single or multiple ALSONIC radar velocity transducers can be used for velocity profiling across the channel in combination with the level transducer by sending the outputs to our multichannel controller (MC) to perform the Area • Velocity flow calculation.
