[0019] The ultrasonic level meter body 3 is connected to the display mechanism 1 through a signal line. The ultrasonic probe 5 is used to monitor the oil and water levels of the locomotive oil pan 18, the locomotive cooling water tank 19, the locomotive axle box and other components in the locomotive. A magnetic suction piece is installed at one end of the ultrasonic probe 5 that is attached to these components, which is used to adsorb the ultrasonic probe 5 on the components.

[0020] The ultrasonic probe 5 emits ultrasonic waves, which are reflected after encountering the measured medium (oil, water) during the transmission process. The reflected ultrasonic signal is detected by the ultrasonic level meter body 3 and converted into an electrical signal, and then processed by the dedicated software in the display mechanism 1. The time difference between the emission of the ultrasonic wave and the echo is analyzed. Combined with the propagation speed of the ultrasonic wave, the propagation distance of the ultrasonic wave can be calculated, and then the liquid level situation can be reflected. The collected liquid level data is processed and calibrated according to the size of the components, converted into the current actual oil volume, and displayed in real time. The display mechanism 1 is also equipped with an alarm system, which can diagnose and warn in real time when the liquid level is detected to be lower than the configured value.
