MicroFlow Pulsar Velocity Sensor

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, and provides a viable alternative where the hydraulics of the site do not allow for a restriction in the channel.
