Hydraulic Testing & Calibration Services

Product Research & Development

Manufacturers and owners of hydraulic equipment such as flow meters, valves, pumps, storm water products and flow measurement instrumentation often come to Utah Water Research Laboratory (UWRL) to take advantage of hydraulic laboratory capabilities and the expertise of professional researchers. The UWRL's professional staff and students help vendors of these products understand product capabilities, solve limitation issues, and product effectiveness at extreme hydraulic cases over varying stages in product development. The Utah Water Research Laboratory has had many success stories with the development of products and technologies. Patents, small business spin-offs, and improved product performance for manufacturers commonly result from research and development work.

The UWRL uses NIST traceable instrumentation to accurately water test, calibrate and verify flow meter performance. Flow meter manufacturers and owners are anxious to determine accurate performance characteristics for their products in order to conserve water, appropriately charge customers, and remain competitive in the flow meter market. The UWRL calibrates all types of flow meters in sizes from 1/4-inch to 72-inch diameter, with flows exceeding 230cfs, including:

  • Ultrasonic meters
  • Venturi meters
  • Flow nozzles
  • Turbine meters
  • Orifices
  • Insert probes
  • Magnetic flow meters
  • Turbine meters
  • Coriolis meters
  • V-cones
  • Open channel measuring devices
  • Velocity probes

The UWRL often constructs simulated sewer lines to provide vendors with opportunities to test open channel flow metering equipment under different pipe sizes, slopes, and water depths and velocities. Other storm water devices tested regularly by the UWRL include static and dynamic storm water grates, storm water contaminant and debris filters.

The UWRL also conducts performance tests on most types of control valves and check valves including:

  • Detection and quantification of cavitation
  • Determination of size and pressure scale effects
  • Cavitation suppression
  • Torque measurements
  • Leakage tests
  • Cycle tests
  • Wear tests
  • Discharge and loss coefficient tests

Pipe tests are also available to obtain friction and minor loss coefficients for pipe and pipe fittings for all pipe sizes and materials.

A partial list of pipe components and valves and flow elements tested at the UWRL include:

  • Steel, PVC, Copper, and Plastic Pipe
  • Pipe Tees, Elbows, Reducers
  • Expansions (Malleable Iron, Weld-In, Copper, Brass, and PVC)
  • Wet and Dry Barrel Fire Hydrants
  • Pressure Relief Valves
  • Air Release Valves
