[0001] The utility model relates to the technical field of ultrasonic liquid level gauges, and specifically, to an anti-fog device for an ultrasonic liquid level gauge. Background Art

[0002] An ultrasonic liquid level gauge is a digital liquid level instrument controlled by a microprocessor. In measurement, an ultrasonic pulse is emitted by a sensor, and the sound wave is reflected by the liquid surface and then received by the same sensor.
