Pulsar MicroFlow Velocity Sensor

Pulsar MicroFlow Velocity Sensor 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.

Pulsar MicroFlow Velocity Sensor Features

  • Operational Cost Saving by high energy cost avoidance, pre-blockage detection, automatic resets and the selection of the most efficient pump
  • Capital Cost Saving by combining HMI, PLC, RTU and level control with no costly logic programming
  • Remote monitoring of flow and level with picture verification for Compliance
  • Modular and expandable to suit simple and complex applications
  • With convenience and safety in mind, the power monitor can be mounted away from the ICA section
  • Patented Asset Management data calculated by the Ultimate which can be displayed locally and remotely
  • Blockage detection
  • Pump Reversing
  • WITS Procotol


  • Advanced pump control
  • Level measurement
  • Flow monitoring
  • Pump performance monitoring
  • Asset management
