Manometer-thermometer autonomous MTA (MTLA)


Stand-alone pressure gauges of the MTA series (MTLA) are designed to register pressure and temperature values, as well as, in the presence of a coupling locator, to detect coupling joints and explosive perforation zones.

They are used in the study of oil, injection, gas and other wells using a scraper wire or other methods of delivering devices to the study area.

Permission to apply № РРС 00-34550 issued by the Federal Service for Ecological, Technological and Nuclear Supervision.



High accuracy and resolution allow the use of autonomous pressure gauges for:

  • building an inflow profile;
  • determination of water and gas-oil contacts;
  • determination of the dynamic level of annular fluid;
  • detection of leakage of coupling joints;
  • studies of reservoir properties.



Setting the operating mode and reading information into the computer is via the USB port.

Setting up to 8 data recording intervals with setting different modes in each interval: the registration period and the duration of the registration interval.

The duration of continuous data recording depending on the registration period is from 284 hours to 3 years.

The duration of continuous operation when using one AA-size battery is up to 300 days.

The use of high-quality materials in the manufacture of pressure gauges ensures their reliable operation in wells with an operating temperature of up to 150 ° C and with an H2S content of up to 30%.

Technological software allows you to set the operating modes of the pressure gauge, check the condition of the batteries, view and print the recorded values ​​in the form of tables or graphs, integrate and correlate the depth of the pressure gauge with the readings of other devices.



Self-contained pressure gauges are available in diameters from 20 to 42 mm, with or without locator couplings, and can have a lower threaded connection for inclusion in the autonomous recording complex.
