Flowmeter, Valve, & Pipe Testing


Since 1965, the UWRL testing facility has performed thousands of flow meter, valve, and pipe tests. World-class staff perform calibrations for commercial, governmental, nuclear, aerospace, and many other applications. Turnaround time for calibrations is generally 2 weeks with appropriate scheduling.

Venturi meterflowmeter testing


Flow meter calibrations at the UWRL use National Institute of Standards and Technology (NIST) traceable instrumentation and have met stringent nuclear safety testing requirements. The size of the UWRL hydraulics laboratory gives us the capability to simulate actual metering installations to ensure the most accurate calibration possible.

Flowmeter testing capabilities:

  • Flowmeter sizes from 1/8-inch to 78-inches in diameter
  • All types of municipal, industrial, and residential flow meters
  • Accuracy and head loss characteristics determined
  • Non-ideal piping configurations and varying water temperatures possible
  • Precise measurements using weight tanks and/or calibrated master flow meters
  • Weight tanks that can receive flows up to 22,000 gpm
  • Maximum flow rate through our largest master Venturi flow meter exceeds 100,000 gpm
  • Handling capabilities up to 40,000 lbs
  • CFD can be coupled with laboratory data to predict meter respons to piping conditions that are not feasible to test in the laboratory
  • CFD can also be used to direct meter design and installation locations

High Performance Regulating Valve


Hundreds of valves of all varieties have been tested at the UWRL in an effort to assist manufacturers and end users. The hydraulics laboratory has also conducted specialized testing of valves going into nuclear service and for aerospace applications.

Valve testing capabilities:

  • Valve sizes rangings from 1/8 inch to 78 inches
  • Flow performance characteristics with valve weights up to 40,000 lbs
  • Cavitation and dynamic torque characteristics
  • Seating, unseating, and sealing performance
  • Nuclear and aerospace applications
  • Valve pressure testing
  • Valve cycle testing using hot and cold water
  • CFD capabilities to test valve performance as well as direct valve design



As a premier pipe test facility, our ability to pass large flows and handle large pipe sets us apart from other laboratories.

Pipe testing capabilities:

  • 500 ft-long channel with large (100,000 gpm) flow capacity
  • Flow tests to establish pressure loss characteristics of smooth wall and profile pressure and non-pressure pipe
  • Burst testing
  • Pipe deformation testing
