The Nuova Rade 197349 content level sensor for stationary marine tanks is designed to continuously convert the liquid level into a unified output signal. The working principle of the model is that the permanent magnet float, together with the liquid level, moves along the rod, which contains an array of reed switches and resistors from 0 to 190 Ohm. The device is 25 cm long and contains a connecting flange for easy installation in a vertical position.
