![]() I don't know where you can get an ultrasonic level transmitter but I use the same type of switch that you have pictured.
I use it with my ATO. I cut a hole in the top of plastic bottle cap and pushed the wire end through the hole in the cap and secured it with the plastic nut. I then thread the wires through a hole I made in the plastic bottle then screwed the cap on to the bottle. The bottle is upside down and secured to the side of my sump at the correct level for my ATO. This way the wires are always dry inside the plastic bottle. Haven't failed me yet. I hope you can visualize it without pics. |

![]() not a answer to you question but I use a float that requires no power just gravity and its never failed me

![]() If it where just ATO then yeah I could figure out a way to just do this mechanically. But its the automatic water change that really requires two switches, or a transmitter.

![]() Doing a quick search on Ebay and reading some manuals seems like I can get a decent level sensor for $150 - $25 on Ebay. Think I'm going to pull the trigger on this one:
Made by flow line, it measures between 2" - 48" with a 3 mm accuracy. Should be good enough. Manual is here if any one is interested. http://www.flowline.com/pdf/disconti...u12-lu13-m.pdf |

![]() Are you running 120v through your switches ? This will cook them in short order
They're best used with low voltage If you must use them on a 120v circuit, check out my thread on how to wire them through a relay Wiring a float and relay to protect your ATO pump and more One of the members posted this sensor link awhile back |

![]() For my ATO and AWC it's 24 VDC, I use 120 VAC for my SW mixing tank.
