ČSN EN 61987-12

This part of IEC 61987 provides an operating list of properties (OLOP) for the description of the operating parameters and the collection of requirements for a flow measuring equipment and device lists of properties (DLOP) for the description of a number of flow measuring equipment types. The structures of the OLOP and the DLOP correspond to the general structures defined in IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in IEC 61987-10. Aspects other than the OLOP, needed in different electronic data exchange processes described in IEC 61987-10, will be published in IEC 61987-92 . Libraries of properties and of blocks used in the LOPs in this standard are listed in Annex C and Annex D.
