Term Definition 

ANSI 

American National Standards Institute. 

Antenna 

A length of wire or similar that radiates (such as a transmitting antenna) or 
absorbs (such as a radio antenna) radio waves. The two basic types are: 
Yagi (directional) or Omni (bi-directional). 

AP 

See Absolute Pressure. 

API 14.3 

American Petroleum Institute Report No. 14.3 addresses the 1992 
equation regarding the AGA-3 method for calculating gas volume across 
an Orifice Plate. 

API 21.1 

American Petroleum Institute Report No. 21.1 addresses the equation 
regarding AGA-8 Fpv or Supercompressibility Factor and the energy 
content of the gas. 

Archive 

A file containing historical records in a compressed format for more 
efficient long term storage and transfer. Totalflow archive records are non-
editable, meaning that when they are stored they may not be changed. 
These records are used during an audit of data. 

ASCII 

American Standard Code for Information Interchange. A very popular 
standard method of encoding alphanumeric characters into 7 or 8 binary 
bits. 

Asynchronous 

A communications protocol where information can be transmitted at an 
arbitrary, unsynchronized point in time, without synchronization to a 
reference time or "clock". 

Atmospheric Pressure 

The pressure due to the weight of the atmosphere (air and water vapor) on 
the earth's surface. The average atmospheric pressure at sea level (for 
scientific purposes) has been defined at 14.696 pounds per square inch 
absolute. 

Audit 

To examine or verify data for accuracy. Totalflow’s DB1 and DB2 records 
may be edited to generate a more accurate representation of data 
information. 

Audit Trail 

Using the Long Term Archive files to justify changes made to records that 
more accurately reflects the correct data. Peripheral information used to 
edit data is recorded without exception, to justify the accuracy of the edited 
data records.  

Audio Frequency 

Generally in the range 20 Hz to 20 KHz.  

Automatic Frequency 
Control 

Similar to Automatic Fine Tune (AFT). A circuit that keeps a receiver in 
tune with the wanted transmission.  

Back Pressure 

Pressure against which a fluid is flowing. May be composed of friction in 
pipes, restrictions in pipes, valves, pressure in vessels to which fluid is 
flowing, hydrostatic head, or other resistance to fluid flow. 

Background Acquisition 

Data is acquired by a DAQ system while another program or processing 
routine is running without apparent interruption.  

Bandwidth 

The range of frequencies available for signaling; the difference between 
the highest and lowest frequencies of a band expressed in Hertz.
