Best Float Switch for Wort Grant?

Post by BREWMASON »

Looking to automate our wort grant pump with float switches. Would these work ok or does another brand work better?

Rather connect my BCS-460 vs use one of these:

The float switch in your link is a generic chinese one that is available on Ebay and other places for $5-$8.

Yes, they work well. I have a few that I'll be incorporating into my setup for BK volume and HLT level sensing.

We use them often at work. They are easy to clean, operate and you can flip the magnet over to change the position from NC to NO depending on what you want. Your gonna want to pull the c-clip and take apart often so grim doesn't build up inside there and possibly cause a hangup....

I just got one of these floats today and want to use it for fly sparge level control. The switch would control my pump on/off function through the BCS. Does anyone have a wiring diagram and programming hints they could share with me! Thanks!!!

I have attached a float switch image that was shared with me. I am still seeking clarification on if this absolutely 100% correct. I would like to have a dual float switch come up through the middle / bottom of the wort grant. That way the whirpooling would not mess with the floats. They could travel up / down without interference.

That dual float switch would likely have 3 wires. One as a common feeding the 5V to each switch and then two returns back to the DINS (one for each switch).

The Dual Float that I have are 4 wire

2 Red = top float

2 black = Bottom Float


So Wire One Red and One Black to 5+ v and the Other Red and Black to different DINs. There is no Ground needed for the DIN.
