The utility model discloses an automatic control working fluid level detection instrument and mainly aims at solving the problems of insecurity and inaccurate detection in manual sounding for working fluid level detection of an oil well at present. The detection instrument is characterized by comprising a subsonic wave sensor, a pressure sensor, a temperature sensor, and an amplification circuit which is matched with the sensors and comprises a sounding module and a data remote transmission module, wherein sampling signals provided by the subsonic wave sensor, the pressure sensor and the temperature sensor are converted through an A/D (analog/digital) conversion module and input to the corresponding digital sampling signal input end of a central controller; the data remote transmission module is connected with the central controller by a bidirectional data flow structure; the sounding module comprises an air pump and a solenoid valve which are mounted on a detection instrument housing; the solenoid valve serv
