MicroFlow Non-contacting Velocity Sensor

MICROFLOW Pulsar’s MicroFlow delivers accurate, repeatable, velocity measurement for liquid flow, either as a stand-alone device or as part of a complete areavelocity measurement system Non-Contacting Liquid-Velocity Sensors MicroFlow builds on Pulsar’s award-winning pipe flow technology and world-leading open channel flow measurement systems. The unit can be installed as a stand-alone sensor delivering data via RS485 Modbus RTU, or instead integrated with a controller and dB level sensor for area-velocity flow measurement in partially filled pipes and channels. Area-Velocity Calculations Area-Velocity calculation using MicroFlow provides a cost-effective flow measurement option compared to the installation of a Primary Measuring Device (PMD), such as a flume or weir, and provides a viable alternative where the hydraulics of a site does not allow for restriction within the channel. Area-Velocity for Channels <1.5 Meter Wide For smaller channels that are less than 1.5 m (4.9 ft) wide, MicroFlow can be combined with the dBMACH3 flow transducer (or another dB Transducer) and a FlowCERT controller to gain accurate area-velocity readings. THE RIGHT METER FOR • Effluent Flow • Open Channel Flow • Applications with No PMD • Area-Velocity • Water & Wastewater • Quarry & Mining Area-Velocity for Channels >1.5 Meter Wide For larger channels such as rivers or effluent flow channels that are more than 1.5 m (4.9 ft) wide, then more than one MicroFlow should be used to provide improved measurement, averaged across the wider flow profile, with the selected dB transducer) and an Ultimate controller for an area-velocity flow system that averages the velocity from multiple sensors across the channel, ensuring accuracy in difficult to achieve straight-run conditions.

Software & Technology The MicroFlow sensor uses K-Band radar technology and Pulsar’s unique analysis software takes readings from the whole width of the channel - if more than one MicroFlow is being used, an average reading will be calculated back in the control unit. To gain the most accurate and reliable reading, the end-user should make sure that the MicroFlow unit is mounted at 45 degrees to the water surface. The K-Band radar technology works by using short pulses of microwaves, which are transmitted by an enclosed antenna on the face of the unit. When reflected off a moving surface,...
