10 Extended Operations
The following extended operation options are possible:
•
External Flowmeter setup (master duty)
•
Base Sediment and Water content
•
Other Standard Volume standards than API2540
• Extra batching functions

•
Meter factor adjustment through Modbus
•
Reynolds Warning function
10.1 External Flow meter (master duty)
The UFP-V has the possibility to act as a Master Duty system. The duty meter is the external flow
meter input. An online comparison is possible over the volume preferred. A good comparison is only
made by comparing the standard volumes of both systems.
Under F9 Controls, F3 Extern the below window can be found.
In this window the following actions can be done (also possible by Modbus input)
• The used K factor can be inputted
•
Comparison tests can be started and stopped
•
A new found K factor after a proving can be committed
Note: Do not forget to save the configuration after a change, only the saved configuration values are
used.
The necessary inputs for the comparison are:
•
The flow signal from the external flow meter must be a pulse input for the UFP-V. An optional
pulse counter on the MP103 card reads in the number of pulses. The K factor (pulse/liter) converts
the counted pulses to a measured proces external volumetric total
•
Recommend is to use the temperature and pressure at external flow meter conditions for
calculation of the standard volume. If the meter is close enough to the ALTOSONIC V system the
