Beyond the specific types of level gauges mentioned above, there are several other types of level gauges that exist. A common one is the fuel level gauge used to report the level of fuel in motor vehicles. Also, there are level gauges that rely on ultrasonic technology or guided wave radar to assess the level of fluids.
Compressed gas such as LNG and LP also have gauges that can be used to assess the amount of remaining gas available. Some of these rely on weight or sense the change in temperature on the tank surface where the vapor-liquid interface occurs.
