Bi-Lateral Intercomparison of Oil Flow Facilities Between NEL and FMC Technologies

Project Description

Bilateral comparison undertaken between the high viscosity oil calibration facilities at NEL and FMC Technologies (based in Erie, PA,US). Intercomparison was to support FMC for commissioning of an ISO17025:2005 (NVLAP laboratory code 200939-0) accredited flow calibrationtest facility for R&D. Both laboratories used different test fluids - nominal fluid viscosities of 2 cSt and 200 cSt.

For the low viscosity comparison, NEL used an EXXON kerosene substitute with a nominal viscosity of approximately 2 cSt at 28 °C. For the high viscosity comparison, NEL used a white mineral oil, Siptech, with a nominal viscosity of approximately 200 cSt at 28 °C.

For the low viscosity comparison FMC used a kerosene/gas oil substitute with a nominal viscosity of approximately 3.3 cSt at 28 °C. For the high viscosity comparison, FMC used refined lubricating oil, with a nominal viscosity of approximately 400 cSt at 28 °C.

Tests were carried out in both laboratories at a temperature of 28 °C using the low viscosity fluid. However the high viscosity fluid tests were completed at 28 °C at NEL and 36 °C at FMC.

A temperature correction factor was applied. Intercomparison flow range for testing from 10 L/s to 90 L/s.
