The invention relates to the technical field of liquid level measurement and particularly provides a liquid level measuring device for an oil well fracturing operation tank car. The liquid level measuring device comprises an operation tank, a liquid level sensor, a current transducer, a micro processor, a display unit and an audible and visual alarm, wherein the liquid level sensor is mounted in the operation tank; the liquid level sensor is connected with the current transducer; the current transducer is connected with the micro processor; the micro processor controls the display unit and the audible and visual alarm to work; the micro processor and the display unit are arranged in an explosion suppression tank; the audible and visual alarm is arranged at the top end in the explosion suppression tank; the explosion suppression tank is mounted behind left and right fenders of a tank car; and a lightning-protection explosion suppression layer is additionally arranged on a circuit board of the current transducer. The liquid level measuring device is simple to operate and suitable for a worker to use, and high in reliability because of the lightning-protection and explosion suppression structure; an alarm signal is independently output by two relays which are used for increasing the alarm reliability; and compared with a conventional ultrasonic liquid level meter, the liquid level measuring device has cold-resistant characteristic and is especially suitable for a cold severe environment in north.
