level sensor.

[robo]

Having my header tank made in ali and wondered if anyone knows of a dinky little level sensor that can be bought that screws into a boss. Not the big plastic things that you see on some of the header tanks or the ones that push into a large grommet.

Thats neat. noticed that was a yank part so looked on a yank site and found this http://www.theautopartsshop.com/auto+car-usa+parts/volkswagen+passat+engine-coolant-level-sensor.html

Just wondered if the us passat was the same as ours or some badge engineered mongrel.

A simple transister circuit with select support components would do the trick.

Need the range perameters of the sensor to work it out.

Its basicly an analogue to digital convertor circuit, i could probably knock up something but it would be a few weeks before i get a change with uni stuff etc.
