Reliability & Engineering Risk Analysis

Failure Mode & Root Cause

Wear and drift

Cause: Abrasive particles in the fluid causing gradual erosion of moving parts, leading to inaccurate measurements and calibration drift over time.

Seal and gasket failure

Cause: Chemical incompatibility with process fluids, thermal cycling, or improper installation causing leaks, contamination, or complete metering failure.

Maintenance Indicators

Audible: Unusual grinding, clicking, or squealing noises during operation indicating mechanical wear or obstruction.
Visual: Visible fluid leaks around seals, gaskets, or connections, or inconsistent/fluctuating readings on display indicators.

Engineering Tips

Implement proactive filtration and fluid conditioning upstream to remove particulates and maintain fluid compatibility with meter materials.
Establish regular calibration schedules using traceable standards and perform preventive seal/gasket replacements based on service hours or cycles.

Compliance & Manufacturing Standards
