Product description

Highlights at a glance

  • Measurement accuracy up to ±0.05% of reading, with high-precision models achieving ±0.02%. As a primary standard in pressure metrology, ideal for pipeline strength testing (125% MAOP verification), wellhead pressure monitoring, and other accuracy-critical applications.
  • Based on hydraulic piston (deadweight) principle, pressure is reproduced directly by standard masses without relying on electronic sensors. Long-term stability far exceeds ordinary digital pressure gauges - no drift, no error accumulation.
  • Standard range 0.5~25MPa (approx. 70-3600psi), high-frequency models up to 60MPa or 600 bar. One system meets pressure testing needs across multiple industrial scenarios - gas pipelines, oil pipelines, wellhead equipment, and steam systems.
  • Ergonomic portable integrated layout with dedicated mass case, bubble level, quick connectors and hoses. No external power required - quick field deployment for pipeline pressure testing, valve testing, and transmitter calibration.
  • Designed specifically for oil and gas industry applications: Buried pipeline leak detection and strength pressure testing Wellhead gas pressure measurement and riser hydrostatic testing Gas pressure monitoring for flow meters at city gate stations Pipeline valve and pressure vessel seal integrity verification
    • Frequently asked questions

    It operates on the hydraulic deadweight principle. Pressure from the pipeline is transferred to a precision piston-cylinder system. Standard masses are added until the force balances the pipeline pressure, allowing highly accurate pressure calculation based on the loaded mass value.

    Standard accuracy is ±0.05% of reading. High-precision models are available with ±0.02% accuracy, making it suitable for pipeline integrity validation at 125% MAOP as required by safety regulations.

    Standard range is 0.5~25MPa (70~3600psi). Higher ranges up to 60MPa or 600 bar are available depending on model. One system covers gas pipelines, oil pipelines, wellhead, and steam system testing.

    Pipeline leak detection and strength testing, wellhead gas pressure measurement, power plant steam pressure monitoring, and gas station flow metering pressure verification.

    Calibrate every 12-24 months at an accredited lab. Use clean hydraulic oil to prevent contamination. Store masses in dedicated case when not in use to prevent damage or rust.

    Deadweight testers are primary standards that physically generate pressure based on physics (P=F/A). They offer higher accuracy (0.05% vs 0.25%) and no electronic drift, making them ideal for verifying other gauges or critical pipeline safety tests.

    Yes. Ergonomic portable layout with integrated carrying case, bubble level, quick connectors and hoses. No external power required - ready for quick field deployment.

    Common causes: air in system (vent lines), dirty oil (replace/clean), misalignment (check bubble level), or incorrect mass loading. If issue persists, piston/cylinder may need professional cleaning or recalibration.
