Dual-pointer pressure indicator systems deliver accurate measurements for mud, cementing, acidizing, and fracturing operations

AOI Compound Pointer Pressure Gauge systems accurately measure and display pump pressures for downhole cementing, high-pressure hydraulic fracturing, or acidizing oil pay operations.
A standard pointer provides a full 360° sweep of the dial, and a vernier pointer offers 4 to 1 resolution for indicating even small pressure changes. The system consists of a 6-inch Pressure Gauge, a Gauge Protector, and a high-pressure Hose.

Features:

• Standard capacities include:
• 4,000, 8,000, 12,000, and 16,000 psi
• 400, 800, 1200 kg/cm²
• 40, 80, 120 MPa
• Durable 517-152 Gauge Protector mounts with
  2-inch NPT sub
• Operational in temperature ranges of -50° to +150° F
  (-45° to +65° C)
• Accuracy rate of ± 1.0% of full indication
• Available in box-mount and panel-mount configurations
• Standard 50-foot hose, with other hose lengths available

Benefits:

• Gauge can be mounted in any convenient location —
  perfect for use on service trucks.
• Vernier pointer provides 4 times more resolution for the same pressure change — measuring small pressure changes caused by formation breakdown, perforation plugs, and fractures.
• Fluid-filled gauge protects readings from truck or rig vibration.
• Operator-adjustable controls enable steady pointer movement.
• Provides all the advantages of the standard pump pressure gauge, with the added accuracy of the vernier pointer.
• Measurements can be easily recorded by hydraulic circular recorders or electronic remote strip recorders.
