ABOUT US

Colorado Engineering Experiment Station, Inc. (CEESI) performs NIST traceable primary and secondary calibration for numerous types of flow meters and fluids. In addition to quality calibrations, CEESI offers calibration-related engineering services, valve testing, and a wide range of flow measurement training services.

Key Company Details



Contribution to Measurement Committees & Standards Development


Throughout the years, CEESI engineers have been heavily involved with a variety organizations involved in flow measurement and standards development. CEESI engineers have:
  • Worked on writing/developing standards for AGA, ISO, and ASME
  • Served on committees for ASGMT, ASME, ISO, AGA, GRI, API, GTI, NAFFMC, and AGMSC
  • Taught presented/instructed at: ISHM, ASGMT, AGMSC, SGA, ISFFM, and MMSS
  • Supervised flow measurement testing for portions of AGA 7



MAJOR TEST AREAS
Major Calibration Test Areas
Iowa Natural Gas Facility

Iowa Natural Gas Facility

The facility in taps into a 42 inch line in order to run natural gas tests on a wide range of meters.

Wet Gas and Multiphase Facility

Wet Gas/Multiphase Facility

This facility can test a variety of fluid mixtures and is often used to help companies test new meter designs.

High Flow Pad

High Flow Pad

This outdoor air test stand can test massive meters with large flowrates.

Missile Bay

Missile Bay

This indoor test area can test meters with high flowrates; it is housed in what used to be a nuclear missile silo.

Main Lab

Main Lab

This large underground area houses a variety of test stands with a wide range of capabilities.

Water Lab

Water Lab

Our water lab can test a wide range of meters types on water.

R and D

R&D

This is another test area for for meters that must be calibrated at high flowrates.

Liquid Hydrocarbon Flow Calibration Facility

Liquid Hydrocarbon Flow Calibration Facility

Built in 2015, this test facility can calibrate meters using liquids at multiple viscosities at low uncertainties.

Cryogenic Flow Calibration Facility

Cryogenic Flow Calibration Facility

Brought online at CEESI in 2017, this facility can test meters using LN2 at -297°F to -315°F.

Porter

Porter

The Porter is used to test very small meters at very low flow rates.

ACCREDITATION
We are accredited by the National Voluntary Laboratory Accreditation Program (NVLAP), which is an independent organization that recognizes quality program for compliance to national and international standards. Read more.
