  1. Remote Gauge for OIL central heating tank


    Please could anyone tell me if they know of such a thing? Ie the gauge
    would be in the house not actually on the tank outside. Maybe with a beep
    alarm that goes off when the tank is getting low.

    Any info gratefully received.

    Thanks in advance :O)

    Manufacturing plants do this every day. Many of the items listed at or are somewhat
    spendy, but they do have "low cost" options on some of their sensors.
    Standard disclaimers apply; I don't get money from either company.

    If you don't really need a continuous output (the tank is exactly
    62.305% full) but can live with a few broad ranges (the tank is
    something over 50% full but less than 75% full), a few float switches
    can be inexpensive. You might be able to adapt a float switch mean to
    turn on a pump for a water tank; if you just use one switch your
    indication is "OK" or "low".

    Another way is to use the gauge you already have and point a $20 wired
    or wireless "spy camera" at it. Run the video output into your TV
    (possibly through a switch box, so you can select cable / DVD / tank
    camera) and you can check it whenever you like, as long as the gauge is

    Your oil supplier might have a ready-made solution, as well.

    Do you want to constantly monitor the level, or just know when it gets
    low? The easiest solution is a magnet on a float and a reed switch set
    at the level you want to be warned. The next easiest is a magnet float
    and a *series* of reed switches. The switches could be connected to a
    string of lights or LRDs and this would give you a continuous display.
    I've also seen a remote sensor That used a string of reed switches
    hooked up to a resister network. The reed switches either switched in
    or shorted out the resisters which form a voltage divider. This gives
    you an analog output proportional to level.

    or you can connect a clcok timer to your furnace and calculate how many
    hours of oil have been used up and how many are left.

    Hello Vødkäjéllÿ,

    You should be able to get one at an oil tank supplier. I remember when
    we lived in Germany the tank had a large gauge inside the house and this
    was installed in the late 60's. So it must be readily available technology.

  7. Expensive is right!!
    This has to be the eaisest and best idea I have seen so far! What an
    excellent idea :O)

    Good Idea, I'll pass this all on>>

    Cheers Matt
  8. I'll pass this info on, however I have no idea what it all means :O)
  9. I don't see how this would work unless the flow was measured, and I don't
    think the owner is adept at pipe cutting. But I'll pass the info on.

    Thanks for replying :O)

  10. Thanks, I've found a few sites that do them now, but the cheapest option
    seems to be the security cam linked to the tv, maybe even a webcam linked to
    the pc :O)

    Hello Vødkäjéllÿ,
    Ours certainly looked cheaper than a webcam. It basically was a small
    copper hose from the house to the tank and a huge meter. So large that
    it could have been read from the other side of the street. You had to
    pull a handle for pressure and then the meter would show how much was in
    the tank. It was quite accurate in comparison with the dip stick. They
    also made some with a pump for a little more money, but I thought that
    would have just been luxury.

    OT: Your name sounds like they have tried to place all the umlauts in
    there that they could. Where did it originate? Mine had only one umlaut
    but I had to drop that because keyboards out here don't have them.

    Regards, Joerg

    Hello Vødkäjéllÿ,
    For a lot of furnaces the fuel flow can be pretty constant. For example,
    with our gas furnace I could exactly predict the metered fuel when
    clocking the runtime.

    Regards, Joerg
  13. Well I'm sure the guy who's oil ran out :O) could too, but he's a busy man
    and I don't know if he has the time to work it out.
  14. I think he's after a visible without checking gauge.

    These are the one's I've discovered... the top one is the cheapest and
    looks the easiest to use...

    You said *sounds* like, I know that when *Vødkäjéllÿ* is read out with a
    computer generated voice it sounds like *Veeekajel*. I used the Microsoft
    Word to chose the symbols (Insert+Symbol) from different languages/text
    styles. It was just to ?m??ll?§? .(embellish) the word and is not a real
    spelling. Quite a few people do it on the english newsgroups.

    Vodkajelly was a nickname from a few years ago, and it just suits me to keep
    it :O)

    Have a good night
