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.
