The Reservoir Group Micro Automatic Gauge is a fully automatic gauge which requires no operator input to acquire data.
The gauge is supplied in monitor mode, a non-recording mode, where it is checking pressure and temperature readings every two minutes. When a user-programmed temperature or pressure threshold has been exceeded, the gauge automatically enters record mode and stores data to memory at a pre-set sample rate. At the end of a survey, the gauge stops recording automatically when pressure and temperature readings fall below the user-programmed threshold values. The gauge then reverts to monitor mode.
This low power gauge is designed for use on multiple runs using only a single AA size battery. A built in real time clock ensures accurate data is stored with real time values and the data from each survey is stored individually in its large memory for easy download and analysis. The Gauge is a compact 10.5” long and is available in 1.25” OD as standard or 1” OD for slim-hole and coiled tubing/small carrier applications.
Our Windows-based Memory Gauge software is easy to operate, even for the beginner, and simple communication steps to download data from the gauge will provide a graphical plot display. For the more advanced user, features such as plot manipulation tools, data export options and Gradient Survey/Report generation tools, are available.
Features
Completely automatic, no operator input required to record data
All data is stored with real time values for easy analysis
1,000,000 data set memory, where 1 second recording rate provides 11.5 days of data
Innovative electronics dramatically reduces power consumption
Long life ‘AA’ size battery is easier to ship since it is not classed as dangerous goods
Overall length of 10.5” makes Wireline rig-up easier and is ideal for carrier applications
Available in 1.25” or 1” OD
