IRZ PERMANENT DOWNHOLE GAUGES allows for real-time monitoring of Rod Pump / PCP Units, or Gas Lift / Flowing Wells in terms of tubing and annulus pressure, annulus temperature, and tubing X, Y, Z-axis vibrations. The product range covers standard 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 environment (upon request)
• Optional metal-to-metal sealing to ensure gas protection
• Wide DH pressure range up to 8700 psi
• Compatible with any drive and SCADA systems using MODBUS communication protocol

Main components

• Downhole gauge
• Surface Readout Unit for installation inside motor drive enclosure or stand-alone surface panel
• Fastening accessories for downhole gauge, i.e. gauge carrier and clamp
• Downhole cable (optional)
• Wellhead feedthrough (optional)
