Endress+Hauser’s calibration facility ‘very best’

19 March 2008

Two months ago Endress+Hauser Flowtec opened a new calibration facility in Reinach, Switzerland. Now, the company says it can calibrate flowmeters more accurately than any other manufacturer. Dr. Gerhard Jost, CEO, said at the opening ceremony that the facility ‘puts us in a position to satisfy even the highest customer requirements without any compromise whatsoever.'

‘The new facility enables the Promass F Coriolis flowmeters we manufacture in Reinach to be calibrated accurately to the specified figure of ±0.05 percent.’

Attending the ceremony was Dr Hugo Bissig, from the Federal Office of Metrology (METAS) and August Schaub, from the Swiss Accreditation Service (SAS).

With 22 qualified engineers, technicians and designers the facility is claimed to produce measurements that deviate no more than ±0.015 per cent from the reference value. This is the equivalent of one champagne glass in one thousand litres of water.

Dr Jost said the calibration accuracy represented the best internationally. ‘As well as performing reliably, our flowmeters must present certification for their high measuring accuracy.’

Endress+Hauser constantly checks all components throughout the production process. The fully assembled flowmeters are then tested, calibrated and adjusted. Calibration means that the flow indicated by a meter is compared with the reference value furnished by the calibration facility, and the meter is then adjusted accordingly.

The company operated in accordance with internationally accepted standards for the accreditation of its products and test methods. The flow calibration facilities are accredited by various national authorities including, SAS, A2LA and CNAS – in accordance with ISO/IEC 17025.
