Automatic echo meter is designed to register the level buildup curve (level depth, casing pressure, echo graph) according to the user-defined time scheme without the human presence.
The device can be operated as:
  • automatic echo meter to register the long-time liquid/pressure curves on the user-defined time scheme;
  • manual device for high casing pressures;
  • remote unit for oilfield automation (supplied with controller and OPC-server).
Can be equipped with the gas balloon in a case of zero or low casing pressure.

Tasks to be solved
  • Automation of long-term multiple measurements of liquid level, casing pressure in various technological processes.
Features
  • Safe muffling and isolation of the discharge when measuring
  • Emergency protection against valve opening
  • Wide operating temperature range from -40 ° С to +50 ° С
  • Possibility to work on wells with low pressure
  • Compact and lightweight, easy to install and start up
  • Real time clock
  • Non-volatile hardware measurement log
  • Explosion-proof design
Capabilities
  • Ability to input the flexible time scheme of operation
  • LogLog, Horner and MDH calculation
  • Data preparation in software EDWin

Software EDWin
Software EDWin is designed for processing of dynamometer, echo level meter, pressure, power measurements received from GEOSTAR-111/112 device (echo/dynamometer system).

Software can perform the following operations:
1. Transfer registered data from GEOSTAR-111/112 device to computer.
2. Prepare echo/dynamometer/power cards (view/modify the parameters).
3. Print the large variety of reports such as graphic, table, complex, and statistic ones. The powerful report designer helps to create and modify reports.
4. Export to RTF (Office Word), XLS (Office Excel), JPG image, to the transport format (BND2, EDW), DYN-format and to the customer database (on demand).
