mPOD ™ Vibration/Pressure/Temperature Gauge
Designed as a permanently installed gauge, the mPOD3 gauge transmits a proprietary protocol when
addressed. Using an addressable scheme allows for multiple mPOD3 gauges or combinations of mPOD3
and mPOD2+ gauges to be powered and communicate on the same, single, conductor line. In addition to
transmitting both pressure and temperature data, continuous monitoring of the gauges head voltage
allows for basic diagnostics of cable integrity during the life of the installed equipment.
Incorporating all metal-metal seals assures life of asset operation. Stringent testing on all eP/Weatherford
gauges adds to the reliability and expected longevity in the permanently installed application. The
calibration and verification testing assures that the gauge meets the accuracy specifications determined
for the design.
Vibration data measured consists of Grms and frequency. The vibration parameter of in-well performance
can assist in the diagnostics and proactive decision process with tubing wear or rod parts. In addition to
rod pumping wells, gas wells may benefit from the mPOD3 enhanced measurement capability to
understand flow induced vibrations on the production string.
