In order to determine the capacities of gas supply networks, these are simulated on the computer using mathematical methods This simulation must be calibrated with the real behavior of the pipe network.

UNION Instruments offers mobile, highly-accurate ESS data loggers of the ESS3 A1 series for the pipe network analysis. These are installed temporarily at various underfloor hydrants in the pipe network. A sudden quantity load of the network brought about for measurement purposes produces corresponding pressure reductions at the various measuring points, which are compared with the drops in pressure calculated from the mathematical model. This enables calibration of the model.

The easy, fast, and straightforward handling of the data loggers allows them to be installed in underfloor hydrants in the large quantities needed for the pipe network analysis. The quality of the pipe network analysis is significantly increased by the high accuracies of the ESS data loggers.

In order to determine the capacities of gas and district heating supply networks, these are simulated on the computer using mathematical methods This simulation must be calibrated with the real behavior of the pipe network.

UNION Instruments offers mobile, highly-accurate ESS3 R1 data loggers for the pipe network analysis. These are installed temporarily at various points in the pipe network and record pressure reductions due to quantity fluctuations. In gas networks, the largest drops in pressure occur at low ambient temperatures (greater gas consumption). For this reason, the data loggers themselves must be highly accurate at ambient temperatures down to -20°C.

The easy, fast, and straightforward handling of the data loggers allows them to be used in the large quantities needed for the pipe network analysis. The quality of the pipe network analysis is increased by the high accuracies of the ESS3 data loggers. The large data memory of the loggers enables them to record measurements over several weeks in order to obtain measured values on the coldest possible (and thus most informative) days.
