Volume Flow" Measurement Type - Siemens Sitrans P500 Operating Instructions Manual

Operate
6.3 Description of the operating functions
Select the "mass" measuring mode with a unit from the mass range and the measuring
range limits. If you have not yet assigned a value to the density parameter, the output value
of 1 kg/l is preset.
The calculation example yields a mass of 250 kg for the "mass" measuring mode at a
density of 5 kg/l.
Note
When the density changes, the measuring range limits have to be adjusted accordingly.

"Volume flow" measurement type

Description
If parameters are to be assigned to the "volume flow" measuring mode, you can select a
"flow characteristic". The "flow characteristic" can additionally be modified with a "correction
characteristic" e.g. for an orifice.
There is also the option of measuring the volume flow bidirectionally.
