CQO:1010PVXFM-3 Section 4
TERM EXPLANATION
Local Display Refers to the FUH1010PVX integral display screen.
Menu Sub-sections of the Installation Menu that you to define specific operational
functions (e.g., RS-232 Setup).
Menu Cell A 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.
RTD Temperature sensors used with energy flow of mass flow systems.
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). Meter 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 flowmeter uses
Site Storage Memory to store configurable operating parameters 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 displaycomputer to store data
such as the flow total, etc.
Spacing Index Refers to the Number Index, used by the flow display computer to determine
the space between the upstream and down stream transducers on clamp-on
systems.
Vaer The meter’s aeration percent output.
Vps The sonic propagation velocity of a pipe.
Vs The sonic velocity of a liquid.
