Anyone heard of this level controller? I'm having a hard time searching this on the net. I get all the national agencies in my search!

 

If, over time, you cannot find "NFLC", please see www.almegcontrols.com . They can supply custom floatless controllers as well as their standard float models.

Thanks Bob Hogg

 

The website you are searching is http://www.national.com for national semiconductor, an IC maker. The device you need is the LM 1042N chip. This is a 16 pin integrated circuit designed for water level detection. The price will be around 4 dollars.
