9.5.13 Pressure Drop Test (EU Regulation)

This measurement is performed to test the serviceability of an existing gas pipe
system (in contrast to the load test and pipe commissioning) and is used to check
the actual condition of the pipes. The pipe system may be in operation or disused.
Adhere to DVGW-TRGI 2018, worksheet G624!
Absolute pressure (parameter of the measuring location) must be
entered to obtain correct readings. If this is not known, it is advisable to
use the value 966 hPa (corresponds to 1013 hPa barometric, 400 m
above sea level).
>
Insert the connector plug of the hose pressure connection kit (0554
1203) into the flue gas socket and lock it in place by turning it slightly
clockwise (bayonet fitting).
Performing the measurement
The pressure socket of the instrument must be free (depressurized, not

closed).

Pressure zeroing has been carried out.
Call up function:
1
Set parameters or enter values.
2
All values that can be modified have a dotted underlining.
Three circle diameters and three pipe lengths can be entered, which
are then used to calculate three partial volumes. The pipe volume is
calculated by adding these three partial volumes.
3
Pressurize the system.
