Flow meters calibrated on accredited test rigs
Back To [Automation Articles]
Mass flow meters are generally used in applications where accuracy is of the utmost importance, which is why Endress+Hauser's Coriolis mass flow meters are individually calibrated using independently accredited test rigs, the company says.
Endress+Hauser calibrates its Coriolis mass flow meters using calibration rigs that have been independently accredited to AS ISO/IEC 17025.
Complying with the requirements of the Swiss Accreditation Service (SAS), the company's calibration rigs are at least 3-times more accurate than the specification of the meters under test, Endress+Hauser claims.
It has devised a new PremiumCal calibration rig which has been accredited by the SAS and offers measuring accuracy to 0.015 per cent.
"The need for process reliability and product quality are on the rise in many industry sectors. Whether balancing flow volumes or dosing extremely expensive fluids, high accuracy flow meters are increasingly in demand. This is particularly true in custody transfer metering of hydrocarbons and natural gas or quality-critical dosing applications were small reading errors can translate into thousands of dollars in lost revenue," said the company.
The most accurate Coriolis meter in Endress+Hauser's range is the Promass F flow meter with a measuring accuracy of Â±0.05 per cent when calibrated using PremiumCal.
Promas F combines accuracy with a high degree of mechanical integrity in terms of pipe vibration and plant stress providing seamless, traceable measuring accuracy and long term stability, says Endress+Hauser.
"Companies can now dependably measure and process costly raw materials and intermediate products, to comply with strict quality specifications and implement optimum process automation to minimise their costs," the company said.
