Electronic Dyno Sounder EDS

Electronic Dyno Sounder EDS



The Electronic Dyno Sounder EDS is a computer based dynamometer and liquid level instrument. It can be used to perform a complete well analysis including motor power/current measurements and acoustic pressure transient data acquisition and analysis.

The hardware of the sonoecho™ Electronic Dyno Sounder is intrinsically safe and ATEX certified. A must when working in hazardous area like the well head. Learn more about ATEX and intrinsically safety.


  • The zero offset is known.
  • The plunger setting depth remains unchanged to the normal operation.
  • Subsurface conditions remain unchanged.
  • Load and displacement transducer in one compact system.
  • Only one cable required to connect the transducers to the Data Acquisition Unit.
  • Optional Amp Clamp available to measure motor current.
  • Digitizes the fluid level data and deep well pump data for easy analysis.
  • Software with many options for customization and reporting.
  • Software allows easy calculation of BH pressure and other important parameters.
