TERM EXPLANATION
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 appropri-
ate.
OpSys ROM The read only memory that stores its basic operating instruc-
tions 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.
Register Refers to a memory location used by the computer to store data
such as the flow total, etc.
RTD Temperature sensors used with energy flow of mass flow sys-
tems.
Site Name A user-entered name that meter associates with a stored Site
Setup. You retrieve 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 applica-
tion. In addition, the meter uses Site Storage Memory to store
configurable operating parameters such as pipe and liquid tables.
Spacing Index Refers to the Number Index, used by the 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.
Transducer Clamp-on flow sensors that the meter uses to measure the flow
rate.
Vaer The meter’s aeration percent output.
Vps The sonic propagation velocity of a pipe wall material.
Vs The sonic velocity of a liquid.
