  • Published: November 1998
  • REF/ISBN: 9780852932353
  • Edition: 2nd
  • Status: Current

Fidelity and security of measurement data was developed in three sections :

  • Section 1: Electric and/or electronic pulsed data cabled transmission for fluid metering systems, first
    published in 1976 as IP 252/76 ;
  • Section 2: Electric and/or electronic data transmission for automatic tank gauging systems, published in 1979;
  • Section 3: Electric and/or electronic data capture for flow metering, published in 1985.

This publication replaces the previous Section 1, while Section 2 is now withdrawn. Section 3 remains
current.

The scope of Section 1 encompasses the security and fidelity of transmitter signals and the transfer of data in metering ; it excludes the meter internal processes. Whilst the first edition set good standards aimed  fundamentally at 'real-time' pulsed data, its revision has been necessitated by advances in technology and changes in defmition/application. This edition has been written to include all existing types of meter and data. Its flexibility should ensure that it will remain valid even with further advances in technology.
