THE NEW GRAVITY ZONE CONCEPT IN EUROPE FOR WEIGHING INSTRUMENTS UNDER LEGAL CONTROL |
|---|
| Roman Schwartz, Andreas Lindau |
- Abstract:
- A new European gravity zone concept has been developed by WELMEC, the European Cooperation in Legal Metrology. This concept is independent of political or administrative borders and is accepted by all WELMEC member states regardless of existing national regulations concerning gravity zones. The new concept is based on gravity zones defined in terms of the geographical latitude φ and the height above sea level h, on a standardised gravity formula used for the adjustment of a weighing instrument to a reference gravity value, and on a uniform criterion for calculating the maximum permissible variation Δg/g within an individual gravity zone. The concept is of advantage especially for weighing instruments of class III. It offers an option that can, but must not be chosen by a manufacturer.
