Electricity Cut Of Device?

[lavalamp]

Hi all,

Has anyone seen invented or bought a device which does the following;

Basically monitors the water level when it drops below a certain leave it cuts the electricity supply to a device i.e. pump etc? Initial idea are some floating ball or something any advice or ideas would be greatly appreciated.

Cheers,

Almost like a auto top-up device but in reverse

Sure, a float switch where down is off/open.

just turn the float switch upside down

Beware, some float switches won't operate in this manner

Just out of curiousity what would you be cutting out if the water got to low?

Currently I have two juwel 240 systems with 2 pumps circulating the water between the tanks; I understand the risk of cross-contamination however are shareing ozone/uv and filtration.

(In the very near future I am planning a sump tank with 2 overflow boxes and 2 return pumps containing all skimmers, filtration etc)

While this is in development I am stuck with circulating the water; I wanted the cut of so if one pump was working slightly faster i would not be blowing air into the other tank;


Hope I made myself clear?

cheers,
