Virtual Linear Pump
Toshiba International Corporation’s
Virtual Linear Pump
(VLP) algorithm allows for direct and
precise control of pressure, flow rate, or level. This is achieved without the concerns, instabilities, or
complexities that are traditionally associated with pumping system control.
This section provides useful setup and operational information of the
VLP
system.
The
VLP
system is initially configured using the
VLP Setup Wizard
selection via Program
Virtual
Linear Pump
VLP Setup Wizard
. Once the
VLP Setup Wizard
is started it must be completed for
normal
VLP
operations to function.
However, the
VLP
parameters addressed while using the wizard or the
VLP Settings
menu selection
are also accessible via their associated direct access numbers for specific adjustments when required.
The
VLP
setup procedure and the
VLP Setup Wizard
setup screens are shown below.
