The LC-3 Flow Monitor provides a stand alone solution for liquid level flow monitoring, requiring only 2 wire connections to an existing Duplex controller. Pump run verification ensures pumps operate within specification.

The Base unit supports Flow Monitoring, Level Detection and Run Verification with outputs supporting status indicators and a Bubbler controller. Level Discriminator output capabilities may be added using the APB-22MRDL expansion unit.

To connect to a Modbus network an APB-EXPMC adaptor will be required. The optional Windows based LC_Config software requires either an APB-EXPMC Modbus adaptor or a APB-DUSB programming cable.

The LC Level Controller family USER MANUAL may be downloaded here.

The LC_Config application sofware provides an Windows based graphical interface for the LC product family. Using an Modbus interface the program allows:

  • Monitoring the state of all control functions
  • Configuring of all operating parameters
  • Project management tools
  • Saving and loading configurations to disk
  • Printing configuration reports
  • Operating remote units in Simulation Mode

The FREE software is available here.

NOTE: The software supports an 'offline' mode allowing the capabilities of the LC family to be evaluated with no hardware connected. To connect to the LC controller a APB-DUSB adaptor is required.
