1010PVNFM-3A
Section 5
Local Display
Refers to the 1010PVN’s integral display screen.
Menu
Sub-sections of the Installation Menu that you to define specific
operational functions (e.g., RS-232 Setup).
Menu Cell
location within a Menu where you define either a single numeric
value or option list selection that supports the Sub-Menu’s function.
Certain view-only menu cells show reference data appropriate to the
current application.
NEGFLOW
Totalizer mode for negative flow total only.
NETFLOW
Totalizer mode that combines positive and negative flow totals.
NOTOT
System function that disables the internal Totalizer.
Number Index
Computed transducer spacing index based on the estimated sonic
velocity measurement. This Index
cannot
be overridden by installer.
Numeric Data
Refers to a value entered into a menu cell. An example would be the
pipe outer diameter.
Numeric Entry
Refers to a number you type into menu cell that stores numeric data.
Numeric Keys
Use the numeric keys to type a numeric value where appropriate.
OpSys ROM
The read only memory that stores its basic operating instructions
and permanent defaults.
Option List
Lists of options presented at menu cells that allow you to select a
either a single item or multiple items (depending on the function
that the menu cell controls).
Parameter
Refers to value (either numeric or list selection) stored in a menu cell.
POSFLOW
Totalizer mode for positive flow total only.
Site Name
A user-entered name that meter associates with a stored Site Setup.
You retreive a particular Site by selecting its name from a site name
list.
Site Setup
A collection of parameters used by the meter to service a specific site
(or location).1010 allows you to store several independent Site Setups.
Site Storage Memory
Section of RAM allocated for permanent data storage. This memory
segment stores inactive site setups (including a backup of active site).
The meter’s Site Setup storage capacity depends on the dynamic
memory allocation as dictated by each application. In addition, the
meter uses Site Storage Memory to store configurable operating par-
ameters such as pipe and liquid tables.
TOTCNT
A totalizer pulse count function used for Batching or Sampling.
Transducer
Clamp-on flow sensors that the meter uses to measure the flow rate.
Register
Refers to a memory location used by the flow computer to store data
such as the flow total, etc.
RTD
Temperature sensors used with energy flow of mass flow systems.
Spacing Index
Refers to the Number Index, used by the flow computer to determine
the space between the upstream and down stream transducers on
clamp-on systems.
Spacing Offset
Fixed transducer offset assigned by the flow computer. This can
be overridden by the installer.
Vaer
The meter’s aeration percent output.
Vps
The sonic propagation velocity of a pipe.
Vs
The sonic velocity of a liquid.
