The depth of working fluid level of an oil well is one of the critical parameters that reveal the condition of down-hole environment. It should be measured periodically and accurately to stabilize the usual operation of pumping units. Acoustic method is currently the most common and most effective measurement method. This paper discuss a kind of working fluid level measuring equipment, which is based on NI single-board RIO embedded real-time processing system. By combing existing analysis method with wavelet transform theory, this device can automatically calculate the sound speed in wellbore annulus, and recognize the waveform reflected by fluid level. Results show that the device can effectively detect the depth of the working fluid level, meeting the needs of normal production activities in oil field.
