Calibration Project

To determine the k-factor (the value by which the observed differential pressure varies from the calculated value) for 13mm, 25mm, 40mm and 60mm AptiFlow probes in a range of pipe sizes from 100mm to 630mm

Phase 1

TURBAR – NAMAS accredited flow calibration facility (courtesy of Endress+Hauser UK) – to provide data for 13mm and 25mm probes in pipes ranging from 100mm to 300mm

Phase 2

Exploratory tests at fan testing facility to determine variations for larger bore applications (630mm)
