1. In a method for monitoring an interconnected pipeline distribution network, for losses resulting from leaks, the network being comprised of a plurality of subnetworks, wherein at least one flow characteristic is recorded and analyzed at check sites for a particular subnetwork at given times in an automatic manner over a test-time interval, and whereby leaks detected in the subnetworks are localized by specific test and localization procedures, the improvement comprising:

  • arranging the check sites across the distribution network in a spatially fixed arrangement, and measuring the flow characteristics during an always equal time interval of about 1/2 hour at least one of once a day, and once a week, at all check points at those times when the regularly measured flow characteristic remains substantially constant over a substantially long time interval.
