Boats and such sometimes have fuel flow meters that you may be able to use. Though I would think setting up a gauge in your tank might be cheaper. May not give you the instantaneous rate of flow but will let you know how much oil is being used.

Oil flows via 10mm pipe from tank to burner (burner 'sucks' oil from tank). Searching the net, I found Swissflow's SF800, which converts fluid flow to TTL level signal. Maybe someone has experience in measuring fluid flow? Any comments on that topic? Any alternatives to SF800? thanks, Aadu Adok _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
