7.6.2 Information on flow measurement
In the "Flow" measuring mode, the device determines a volume or mass flow value from the
differential pressure measured. The differential pressure is generated by means of primary
devices such as Pitot tubes or orifice plates and depends on the volume flow or mass flow. Four
flow measuring modes are available: volume flow, norm volume flow (European norm
conditions), standard volume flow (American standard conditions) and mass flow.
In addition, the Deltabar S software is equipped with two totalizers as standard. The totalizers
add up the volume or the mass flow. The counting function and the unit can be set separately
for both totalizers. The first totalizer (totalizer 1) can be reset to zero at any time while the
second (totalizer 2) totalizes the flow from commissioning onwards and cannot be reset.
• By means of the FieldCare operating program, a Quick Setup menu is available for each of the
measuring modes pressure, level and flow which guides you through the most important basic
functions. With the setting in the MEASURING MODE parameter, you specify which Quick
Setup menu should be displayed. ä 37, Section 7.4 "Selecting the language and measuring
mode". No Quick Setup menus are available for the FF configuration programs.

Changing the measuring mode affects the span (URV)!
This situation can result in product overflow.
‣If the measuring mode is changed, the span setting (URV) must be verified in the
"Calibration" "Basic Setup" operating menu and, if necessary, reconfigured!
