Downhole monitoring systems for rod-pumps/ PCP/gas lift or flowing wells

THE PERMANENT DOWNHOLE GAUGES OF IRZ are designed to monitor realtime parameters of a rod-pump/ PCP system or a gas lift/ flowing well: tubing & annulus pressure, annulus temperature, and tubing X, Y, Z-axis vibrations. The product range includes standard temperature and high-temperature (quartz) gauges.

Features

  • Accurate monitoring
  • High data update rate
  • Field proven fail-safe design and hi-rel components
  • The high-accuracy quartz gauge is available for high-temperature applications 200 °С and 230 °С
  • Compact sizes (ø 28 mm)
  • Resistance to H2S containing media (at request)
  • Optional metal-to-metal sealing to protect against gas intake
  • Wide DH pressure range up to 8700 psi
  • Compatible with any drive and SCADA systems using MODBUS communication protocol

Major components

  • Downhole gauge
  • Surface read-out unit for installation inside a motor drive or a stand-alone surface panel
  • Fixing accessories for the downhole gauge: gauge carrier & clamp
  • Downhole cable (optional)
  • Wellhead feedthrough (optional)
