Wireless Tank level monitor: the iTank pressure sensor continuously measures levels of fluids. Very accurate, it is suited for fluids in tanks up to five meters deep. It can be used for diesel, fresh water, waste water, black water, and oil tanks (except for gasoline tanks). Unlike most tank sensors, which only work with rectangular tanks, the iTank pressure sensor can be calibrated for irregular tank shapes, so you know the true volumes of fluids in your tanks.
