Precision Flow Meter Calibration with 4:1 Accuracy Reference Weigh Standards

Flow meter accuracy is critical for industrial processes, custody transfer, and regulatory compliance. At Tactical Flow Meter, we utilize precision M1 weigh standard to deliver a better than 4:1 accuracy.

What Is A 4:1 Accuracy Reference Standard?

The 4:1 ratio represents the relationship between the uncertainty of the reference standard and the device under test. Our precision weigh standards maintain an accuracy four times better than the flow meters being calibrated.  For example, when calibrating a flow meter with ±0.1% accuracy, our reference standard operates at ±0.025% accuracy or better.

Why Reference Weigh Standards Matter

Gravimetric Calibration Advantages:

• Direct mass measurement eliminates density assumptions

• Temperature and pressure variations don't affect weighing accuracy

• Provides absolute reference independent of fluid properties

• Enables calibration across wide flow ranges

Traceability and Compliance:

• NIST-traceable mass standards ensure regulatory compliance

• ISO 17025 compliant calibration procedures

• Documentation meets custody transfer requirements

• Satisfies quality management system standards

Our Calibration Process

Pre-Calibration Assessment: We evaluate your flow meter's current performance and identify any drift or systematic errors before beginning calibration.

Controlled Test Environment:

• Temperature-controlled facility minimizes thermal effects

• Vibration isolation ensures stable weighing conditions

• Multiple fluid types available for application-specific testing

Multi-Point Calibration:

• Minimum five flow rates across the meter's operating range

• Statistical analysis of repeatability and linearity

Documentation and Certification:

• Comprehensive calibration certificates with uncertainty statements

• Before and after performance data

• Recommended recalibration intervals

• Maintenance recommendations
