MicroFlow delivers accurate and repeatable velocity flow measurement, either as a stand-alone device or as part of a complete area velocity flow meter system. Velocity x area calculation using MicroFlow provides a cost-effective flow measurement option compared to the installation of a primary measurement device, such as a flume or weir, and provides a viable alternative where the hydraulics of a site does not allow for a restriction of the channel.
For channels less than 1.5 m (4.42 ft) wide, MicroFlow can operate as a stand-alone sensor, or be combined with the Velocity Interface controller. For channels that are more than 1.5 m (4.92 ft) wide, MicroFlow can be combined with a dBMACH3 flow transducer and a FlowCERT controller, more than one MicroFlow sensor is often needed – in such cases, these sensors can be combined with a dBMACH3 flow transducer and an Ultimate Controller.
