6.4 eference conditions
To configure “ tandard” or “Norm” conditions.
Reference conditions are used to calculate volumetric flow to so-called
“ tandard” or “Norm” conditions. This setting is important for gases
because the volume of a gas varies with pressure and temperature.
Parameter Values emark
tandard 1000 hPa, 20 °C elect this option when the gas to be measured is
compressed air.
Norm 1013.25 hPa, 0 °C elect this option when the gas to be measured is
nitrogen or another gas.
Customer
elect this option when it is necessary to convert
the flow at the compressor outlet to the flow in
the inlet suction state, that is, when the air
production capacity of the compressor needs to be
expressed by FAD (Free Air Delivery). Once
selected, the user has to manually enter the
reference temperature and reference pressure
values for the operating conditions.
6.5 Factory settings
These settings are ex-factory and not changeable by users.
Parameter emarks
Filter grade Enter a value between 0 … 127 as the filter grade. It's a damping of
the flow value which is used to stabilize the flow rate in systems

where the flow is very unstable. A high value means a very high
damping (slow response).
Profile factor The profile factor is the ration between average flow in the pipe and
the centre flow.
6.6 Counter settings
To set the consumption counter to a new start value. ome flow sensors
work bi-directionally and therefore have a standard counter and a
reverse counter.
