Happy Jax 3 Posted November 20, 2007 Share Posted November 20, 2007 I am looking to install a water tank level indicator. (You can guarantee you will run out of water when it is most inconvenient). I am a little bit nervous of cutting holes in stainless steel tank to fit a sender unit. How can you ensure that no swarf will drop into the tank? I have found a company Henderson Plastics that supply a kit for this purpose, it uses an inline pressure sensor to be installed in the outlet pipe adjacent to the tank. Has anyone used a system like this? If so how accurate is it? Can anyone advise of any other suggestions or options available? Your help would very much be appreciated.

Antares_9 Posted November 20, 2007 Share Posted November 20, 2007 Plenty of Vasaline or non toxic grease on a GOOD quality hole saw, go slowly, clean the swarf and Vaso off 3 or 4 times during the process and fit a strainer inline before the water pump and you will be fine :-D :-D Quote Link to comment Share on other sites More sharing options...
jillR Posted November 20, 2007 Share Posted November 20, 2007 ive just bought two neodymium magnets on ebay i can recommend them unless you have a pace maker as they are very very strong. the ones i bought are 20mm x 10mm disc with a hole through the middle. i bought them to use for tools over board but i think it could work well for your job. i bought two for £7.50 inc p +p jill p.s. you will have problems removing the swarf from the magnet when my two magnets got together i had to use a knife to separate them Quote Link to comment Share on other sites More sharing options...
Antares_9 Posted November 20, 2007 Share Posted November 20, 2007 Sadly Jill, non ferous tank, though I agree magnets are helpful when working with ferous material.. :-D :-D Quote Link to comment Share on other sites More sharing options...

Antares_9 Posted November 20, 2007 Share Posted November 20, 2007 lol just too eager to brag about my new toy jill Rightly so Jill, you can find a complete tool kit for free with a good magnet, a good investment, and you can make pretty patterns with iron filings and a piece of glass too. :-D :-D Quote Link to comment Share on other sites More sharing options...
Happy Jax 3 Posted November 24, 2007 Author Share Posted November 24, 2007 Thanks ANTARES_9 Have you had any experience with the inline pressure sensor as a level sender unit? May save drilling holes in tank. Quote Link to comment Share on other sites More sharing options...
Antares_9 Posted November 24, 2007 Share Posted November 24, 2007 Well, if sensitive enough to sense a "HEAD OF WATER" then they should be OK but I'm not familiar with them. Quote Link to comment Share on other sites More sharing options...
