Flow Meter Calibration & Laboratory Services
NIST-Traceable Flow Meter Calibration Services for Liquid & Gas Systems
PFS provides a full range of flow meter calibration services for liquid and gas applications, using our in-house laboratory and trusted third-party facilities.
Our in-house calibration laboratory offers water flow calibration for line sizes up to 8” NPS and flow rates up to 500 GPM. Using NIST-traceable master meters and Rosemount transmitters, we calibrate differential pressure flow elements and most other meter types. This capability also allows us to validate new designs and challenging applications while helping reduce the time and cost associated with outside testing.
Extended Capabilities Through Trusted Laboratory Partnerships
PFS extends its flow meter calibration services through trusted third-party facilities, including Verdantas Flow Labs and the Utah Water Research Laboratory.
We also partner with calibration laboratories to offer computational fluid dynamics (CFD) analysis for applications too large for full-scale calibration or to help improve the accuracy of an existing flow measurement application. This approach allows evaluation without removing the meter or building a physical model of the meter and piping for flow calibration.


Verdantas Flow Labs
Verdantas Flow Labs brings decades of expertise in flow measurement, hydraulic testing, and applied engineering. Its Alden campus is North America’s oldest continuously operating hydraulics laboratory. Together with its Anderson, SC, campus, it offers extensive facilities for physical testing and numerical analysis.
Utah Water Research Laboratory (UWRL)
The Utah Water Research Laboratory (UWRL) at Utah State University brings six decades of experience in water and environmental research. As one of the largest university-based water research facilities in the United States, it offers specialized facilities and expertise in hydraulic testing and flow measurement.
