Drill stem testing tool gauge carrier DGA Cased hole

The Gauge carrier will be designed as per testing requirements, for example to test Annular pressure or Tubing pressure, how many gauges will be carried, the carrier sizes will be also affected by gauges sizes,i.e. OD, Length.
Normally the gauge carrier connects with its adapter which will connect with carrier directly.

The designed gauge carrier is used for carrying four electric pressure gauge or temperature gauge,  record annular pressure(Temperature) and tubing pressure(temperature) data.

The gauge carrier apply to the pressure or temperature gauge in 5 inch outer diameter, length in 28inch, the gauges connect with adapter which will be installed with carrier, the gauge protector ring will hold the gauge on to carrier, the gauge carrier is in full bore type easy for special downhole testing job.

The gauge carrier is composed by three mani parts which is top connector, bottom connector and carrier body, there are four slots in carrier body to hold total 4 gauges, each slot length is about 36" which is easy for gauge installation.
