MicroFlow-i Pulsar Sewer Overflow

Pulsar’s MicroFlow-i delivers accurate, repeatable velocity measurement for liquid flow, either as an individual sensor or by providing HART communication protocol or a 4-20mA loop powered signal into a system.

MicroFlow-i's extremely low power consumption makes it the ideal velocity solution for sewerage network monitoring, spill monitoring, combined sewer overflows (CSO), sanitary sewer overflows (SSO), Event Duration Monitoring (EDM) and all remote installations where mains power is unavailable.

It's lightweight, compact design makes installation simple, especially within confined spaces and requires no interruption to normal operational flow.


Ultimate Features - End to End Cost Savings

  • 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
