I would like to use a pressure sensor to measure the level of water in a water tank. Being a cheapskate I was going to use the oil pressure sender from a car but I calculated that for 1m of water I would only get 1.4psi (0.1bar). Does anyone know where I might find a cheap pressure sensor for such a task? Jaycar have a sensor but I'm not sure if it likes water:
