Mmm thanks Mike, if I read the bumf right the float just dangles by the cable from the roof of the tank? The weight pulls the cable down and the position of the float relative to the weight turns the switch on/off? Yes, that's more or less it  The key thing is no need for electronics, no holes below the level of the fluid / in the wall of the tank, no pivots to seize up, a switch that will easily last a few hundred thousand operations and everything is sealed. It's a fit and forget solution. -- |

However I just seen they can be longer and have 2 switches, lower and upper.... 500 mm might work but the water level in the tank doesn?t get as close to top of the tank (and so mounting point) as the top float switch in the ones I've seen so far... Thanks though Adam, I'll look further into them. -- Jim K ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

TIA A sensitive pressure gauge installed at the tap end should do the job by measuring the head of water. Would only work when the tap is shut. You "might" get enough adjustment range out of a washing machine water level sensor. Older machines will probably have ones with adjustment screws and you could add extra spring pressure to measure a few feet rather than the usual few inches in a WM application. Would work with battery, light and push to read on a KISS principle. |

Thanks Brian. You got me with the electronics idea, I'm not savvy enough! Other idea, is a simple float and lever on the spindle of a pot which is part of a bridge circuit driving a plus or minus meter. -- Jim K ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |

The 6ft tall c.1200 litre tank is the other side of a wall from where the gauge reading c/would be done, and it contains water. Essentially I want to know when the tank is being over depleted. It should refill constantly but if there's a supply issue, measuring (even roughly) the level in the tank is the easiest way to detect that issue and deal with it promptly before the tank is emptied. Being able to check that it is full in the morning /last thing would be sufficient I suppose... Any ideas anyone? TIA A sensitive pressure gauge installed at the tap end should do the job by measuring the head of water. Would only work when the tap is shut. Er no. The output of the tank is pumped so pressure at any taps would be independent of tank water level... until there's no water to pump so no pressure. Doh! I did not know that vital bit of info. Until then I thought it was a neat solution! I would expect the pump to only run when it detects a flow and I very much doubt that there would be any residual pressure from the pump when there isn't any flow. Peter |

I accept Jim thinks I'm as clueless as he is, and don't care. Idiots always think everyone else is equally idiotic. No, I'll stop there. In fact I won't come back to read his reply. There is nothing constructive to add. |
