Indicator for determining fuel level in a liquefied petroleum gas fuel tank, for motor vehicle use, has an array of optical sensors arranged vertically in an epoxy resin transparent support within the fuel tank

摘要

Indicator has an array of optical sensors arranged vertically along a support (8) within the fuel tank. The sensors (9) are embedded within a transparent synthetic resin so that a light beam emitted from one of the luminous light sources belonging to the sensors is transmitted and then reflected back from the tank wall to the corresponding sensor receiver.
