Measuring technology for flow rate, mass flow rate and flow velocity



Conformity assessment for expansion of DAkkS accreditation for flow rate in Höntzsch calibration laboratory

An external evaluation for the expansion of our existing DIN EN ISO/IEC 17025:2005 accreditation to include volume flow, took place from 29th - 30th September 2015. During this time the assessor, Alexander Wolf from the PTB (National Metrology Institute of Germany), gained a comprehensive overview of procedures in the laboratory and was present as a comparative measurement with a PTB turbine gas flowmeter was carried out on the AVP (atmospheric volume flow test bench).


The addition of the DAkkS accreditation for volume flow / flow rate of gases complements our already existing service for DAkkS-accredited calibration for flow velocities. The AVP covers a flow rate of 1.5 m³/h to 5,500m³/h with the slightest uncertainty of 0.25 %. Our wind tunnel for flow velocities is accredited in the range from 0.1 m/s to 70 m/s.


This means that in future all Höntzsch measuring instruments can be calibrated in our own calibration laboratory in conformity with DIN EN ISO/IEC 17025:2005.
