Pulsar Measurement - Model MicroFlow -Non-contacting Microwave Liquid Velocity Sensor

MicroFlow can be installed as a stand-alone velocity sensor delivering data via RS485 Modbus or integrated within a complete system when combined with FlowCERT or Ultimate controller and dB series transducer.

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.
