1.4 Calculated values
Pressure units – conversion to mbar, hPa, Pa, mm·H
2
0, PSI in accordance
with generally applicable conversion rules
Temperature units – conversion from °C to °F in accordance with generally
applicable conversion rules
Flow rates – Prandtl measurements displayed in m/s, automatic continuous
density correction based on temperature signal
Range: 2–150 m/s
Pipeline volumes automatically from 0.0 to 1000.0 l (tested to 250.0 l)
Leakage rate (0.0 to 300.0 l/h) – l/h in accordance with DVGW-TRG work-
sheet G 624. The physical data needed to convert diverse gas types can be
extracted from a database stored in the device.
Pressure drop – pre-assessments and main assessments in accordance
with DVGW-TRGI worksheet G 600
