ことを特徴とする低レベル警報装置。 A low level sensor is provided at a low position in the fuel tank, and when the fuel level fluctuates around the low level sensor installation position and the low level sensor is in a dry or wet state, the sensor output of the low level sensor is In a low level alarm device configured to output an alarm signal from an alarm signal output section based on a value processed by a level detection section, the alarm signal output section is turned on and off based on an input signal to output an alarm signal. Between the alarm signal output section and the level detection section, a sensor output subjected to signal processing from the level detection section when the low level sensor changes from the dry state to the wet state is integrated to a predetermined value. 1. A low-level alarm device comprising: an integration/delay circuit that outputs a signal having a delay time of 1 to the alarm signal output section.
