How to Choose

How DP Flow Measurement Is Backed by Research and Standards

Differential pressure flow measurement is founded on classical fluid mechanics and is supported by international standards and modern metrology practice. Standards such as ISO 5167 for orifice, Venturi and nozzle meters define geometry, installation and uncertainty analysis. Laboratory and calibration studies show that, when installed and calibrated correctly and paired with modern transmitters, DP systems can deliver predictable uncertainty and excellent repeatability across wide flow ranges. Recent advances in transmitter electronics, onboard diagnostics and digital communications have improved stability, reduced drift, and simplified integration with flow calculation software and laboratory data systems.

Key standards: ISO 5167 series for DP flow devices and recognized calibration traceability to national labs (NRC/NIST) used in Canadian labs.

Peer-reviewed and calibration laboratory reports indicate properly configured DP systems routinely achieve low single-digit percent uncertainty and, in many lab setups, sub 1 percent expanded uncertainty for well-conditioned flows.

Modern transmitters with differential sensor technology, digital compensation and HART or fieldbus connectivity reduce long-term drift and support automated correction and diagnostic routines.

Flow calculation and uncertainty software that implement ISO 5167 algorithms simplify converting measured differential pressure to volumetric and mass flow, improving reproducibility between labs.

Best practice research highlights the importance of matched primary device geometry, correct upstream and downstream piping, and periodic calibration to maintain validated uncertainty.
