Echometer SUDOS automat 2

Echometer SUDOS automat 2 is designed for automatic control of the fluid level in oil producing wells. The tool monitors the static and dynamic level, records build-up and drawdown curves, and automatically records gas pressure in the annulus at the wellhead.



  • Automatic valve enables fully automated measurements
  • World’s most compact echometer
  • Mono-unit design for cable-free operation
  • Vibration, impacts, wet-proof resistance
  • Operating temperature range varies from -40°С to + 50°С /-40 to +122 F
  • Software DB SIAM for processing and storing of measured data.
  • If no excessive pressure is present, the tool can be connected to an external pressure source (gas-cylinder set GBO-02)
  • All the measured data are digitalized during the measurement process and then stored and transferred in the digital format.
  • Delivery set of device includes Acoustic pulse generator GAI 01 for generating acoustic signal when the annular pressure is low
