Any digital input to a meter (usually a turbine) that is used to measure
pulses over a time period. This calculates volume and flow rate for each
period of time.
An operational mode used by the LevelMaster for measuring single
float levels by transmitting a pulse to the primary windings, reading the
voltage level on both the primary and secondary windings and using a
calculation whereby one is subtracted from another to determine the
single fluid level.
Any digital output that is used to measure pulses over a period of time.
Frequency of Pulses in a predetermined time frame represents a value
to be used in calculating volume and flow rate.
RF for short. That part of the spectrum from approx. 50kHz to
gigahertz.
Electromagnetic radiation which is emitted by electrical circuits carrying
rapidly changing signals, as a by-product of their normal operation, and
which causes unwanted signals (interference or noise) to be induced in
other circuits.
See Random Access Memory.
A lithium backed storage chip. Also see Random Access Memory.
Acronym for Remote Alarms Monitoring System.
Onboard read/write volatile memory, generally used for application
variables and the file system. Data stored is lost if power is removed
(volatile).
Those values over which a transducer is intended to measure, specified
by its upper and lower limits.
The ratio of the maximum flowrate to the minimum flowrate of a meter.
The number of ampere-hours a cell/battery can deliver under specific
conditions (rate of discharge, cut-off voltage, temperature).
Natural gas that has not been processed.
A mixture of natural gas liquids that has not been fractionated or
separated into its various components.
Communication abbreviation for Results Bus.
Communication abbreviation for Received.
Acronym for Relative Density.
Refers to Totalflow's SRam Drive (solid state memory chip) located on
the main board, used to store data and configuration files. The RDrive
is a lithium backed, volatile memory chip and is not affected by a warm
start.
Computer memory in which data can be routinely read but written to
only once using special means when the ROM is manufactured. ROM
is used for storing data or programs (e.g. operating systems) on a
permanent basis.
Data acted upon immediately instead of being accumulated and
processed at a later time.
