Wireless echo meter

Wireless echo meter GEOSTAR-111.EW is designed to register liquid level depth and measure casing pressure in the annular space of oil&gas wells with wireless method.
Wireless echo meter GEOSTAR-111.E is designed to register liquid level depth and measure casing pressure in the annular space of oil&gas wells.
The measurement is based on echoed acoustic signal reflected from the gas-liquid boundary and joints analysis.
Can be used with smartphone to register data.

The valve is designed to create the acoustic impact for the wells with overpressure.
Acoustic signal generators (UGAS / Gas Guns)
The units are designed to create a sound wave in wells with or without pressure. Includes a rubber crimped pump as standard for measuring levels up to 1000 meters. Additional equipment may include a hand pump, a compressor or a cylinder with compressed air, which allows you to measure levels up to 4500-6000 meters.

  • Rubber Crimped Pump: 0 MPa (0 psi) | 8 – 2 000 meters
  • Manual Pump: 0 – 0,5 MPa (72.5 psi) | 8 – 4 000 meters
  • Air Car Compressor (GIG-103): 0 – 0,8 MPa (116 psi) | 8 – 4 500 meters
  • Gas Cylinder (GIG-104): 0 – 3 MPa (435 psi) | 8 – 6 000 meters
Gas Gun types for wells with pressure
  • Valve assembly*: 0,1 – 40 MPa (14.5 – 5800 psi) | 8 – 4 500 meters
  • *The unit is designed to create a sound wave in wells with excess pressure by short-term pressure relief in the annulus.
The software product EDWin is designed to process and analyze data from sensors (level, load, temperature, pressure, flow rate), prepare and print reports, export / import data.
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).
