24.2 Data &o""ers

?ata oggers are the instruments used to permanently or partially record the variable

parameters of a process, aiming at the systematic recording of operating data necessary for

the perator to proceed to study and further analysis. !n essence, such instruments, if analog,

record on a paper surface "calibrated depending on the use# changes to the operating

parameter in time. $igital data loggers record measurement data, depending on the desirable

settings, in a digital memory from %hich they can be retrieved using a computer and beanaly&ed using suitable soft%are. !n this %ay and by using data loggers, the perator of a

system is able to store the various operating data for their re'uired processing and for future

use. (uch instruments are used in many transmission system operation applications "e.g.

metering data for gas pricing at delivery Points&.

24.3 #ummin" 3nstruments

Summing 0nstruments %hich are also called meters "analog)mechanical or digital# record the

overall value of an operating variable for a given time period, during %hich the instrument or

the metering device for a given parameter had been operating. (uch summing instruments

%hich are %idely used in the natural gas system such are for instance* the instrument

recording the overall volume of the natural gas that has passed through a turbine meter or

other type of meter during a certain period at the reference system +etering and Regulation
