  • Method of data communication with multiple liquid level detection sensors connected to a central processing unit, and liquid level detection system
    Patent number: 10121348
    Abstract: A method of data communication with a selected sensor of multiple liquid level detection sensors connected to a central processing unit includes the steps of: a) transmitting by the central processing unit directly or indirectly a communication signal to the selected sensor of the series of multiple sensors, b) upon receipt of the communication signal by the selected sensor, processing the communication signal in the selected sensor. A liquid level detection system, in particular a liquid overfill prevention system for multi compartment liquid tank trucks, includes two or more liquid level detection sensors, preferably arranged in series, and a central processing unit, where at least one of the two or more sensors includes a sensor processing unit comprising a storage unit.
    Type: Grant

  • Optical liquid level detection sensor and liquid overfill prevention system comprising such sensor
    Patent number: 9869576
    Abstract: An optical liquid level detection sensor includes a light source for emitting a light beam, a liquid contact surface, and a light detector, where the light source is arranged to emit a light beam towards the liquid contact surface, which liquid contact surface reflects or transmits the light beam in dependence of liquid being present on the liquid contact surface, where the light detector is arranged to receive the light beam after reflection on the liquid contact surface, where the sensor includes an at least partially transparent ring element, and where the liquid contact surface is formed by an outer surface of the ring element.
