Water tank level indicator

Recommended Posts

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.

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


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

:oops: lol

just too eager to brag about my new toy


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
