The liquid level is indicated by an attenuation between transmitted and received signal across a sensor tip in the lquid. If the attenuation exceedes an internal threshold- sensortip outsidethe liquid or liquid temperaturehigher than a determinedvalue - a squarewave alarm output indicates an unsufficient liquid condition.
