New Flow Calibration Facilities Are Worlds Best
Endress+Hauserās new full-scale calibration rig in Greenwood, Ind., is the first major flow calibration facility built in North America in a generation. Combined with the new flow calibration facility Endress+Hauser has just opened in La Porte, Texas, and with the home calibration facility in Reinach, Switzerland, and others, Endress+Hauser says it intends to provide a uniformly high standard of measuring quality, worldwide.
The new calibration facility in Greenwood produces measurements that deviate no more than ±0.015% from the reference valueāequivalent to about the contents of one champagne glass in 265 gallons of water. In all, 30 influencing variables were taken into account in order to achieve the excellent performance of this facility.
The normal calibration test for magnetic flowmeters is a run against a āCoriolis towerā made up of multiple Endress+Hauser Coriolis mass flowmeters. At regular intervals, the tower itself is calibrated against a gravimetric flow tank, which itself is calibrated against known weights several times a year. āThis investment enables the flowmeters we manufacture in Greenwood to be calibrated accurately,ā explains Peter Blaser, general manager of E+Hās Greenwood flow manufacturing facility. āThis represents the very best in the international league.ā
Coriolis mass flowmeters can be calibrated accurately to the specified figure of ±0.05%, Blaser says. The facility can also calibrate magnetic flowmeters up to 48 in. diameter at up to 33 ft per sec velocity (10 meters per sec). Vortex shedding flowmeters also are calibrated in Greenwood.
E+Hās Gulf Coast Calibration and Service Center provides flow, pressure, temperature and wet chemistry sensor calibration service, either in-house or on-site. āWe expect to work on most manufacturersā instruments,ā says Jerry Spindler, product group manager, āas well as doing maintenance training in our new state-of-the-art training facility, which includes a digital communications lab.ā
Water is pumped from three neoprene rubber-lined underground tanks through a UV sterilization system that removes bacterial and algae growth. When a calibration run is required, pumps shunt the water through the Coriolis meter tower to the appropriate meter run. The entire system is automated. Even the self-calibration system is automated and operates at night, so as not to disturb production.
E+Hās calibration facilities are accredited by widely different national authorities, including SAS, A2LA and CNAS in accordance with ISO/IEC17025. In addition, all test resources are seamlessly traceable back to national standards, such as NIST, and are subject to periodic inspection by national standard authorities.
The new E+H calibration facilities are specifically designed to interface with Endress+Hauserās Life Cycle Management system, W@M. Available in two versions, the web-based W@M Portal or the PC-based W@M Enterprise, this system provides detailed data for asset management of an end userās installed base of E+Hās products.
W@M provides information for any installed E+H product, including complete spare parts lists, including drawings that are specific to that product; product availability information; order code and configuration details; serial numbers and the customerās assigned instrument tags; original calibration and 3.1b certificates; operating manuals, safety instructions, and information on service and repair, including service reports.
Calibration and repair information from the Greenwood or Gulf Coast facilities is entered directly into W@M, providing a ālive dataā look at the installed data base at any time in the productās lifecycle.Ā
