Matherne Instrumentation’s diaphragm protector is designed to keep well fluids from entering a pressure system’s internal parts with hose lengths up to 50 ft. Matherne Instrumentation’s piston isolator is designed to keep well fluids from entering a pressure system’s internal parts with hose lengths up to 140 ft.

Matherne Instrumentation’s 4:1 debooster is designed to also serve this purpose while reducing line pressure by a ratio of 4:1. This allows the operator at the panel to see only 25% of the actual pressure seen at the manifold.

ADVANTAGES:

• Gauge can be mounted in any convenient location, including service trucks.
• 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.
