Blackwater Level Sensor


The 7014 Blackwater liquid level holding tank sensor has been designed for all applications where consistently reliable and maintenance-free measurement of Black and Grey water is needed. Tank profiling software provides compensation for irregular tank shapes and multiple output options, offering compatibility for the widest range of installations.

The Blackwater holding tank sensor has a probe element which goes into the tank and is robust and tough enough to tolerate the significant forces that are caused by sloshing of the contents in rough seas. The conductive level sensor measurement is a solid-state technology that does not have any moving parts.

The sensor consists of a smooth, non-stick probe without any holes for fluid flow in it, preventing being clogged or jammed by solids that can prevent operation. The sensor’s outputs have been configured so that it can be used with existing gauges and system display screens.


  • Suitable with Blackwater, Greywater, Salt & Fresh water.
  • Non-stick coating.
  • Does not require cleaning.
  • Wireless solution available.
