Flooded Interface measurement: There is no air layer in the tank, there is only fluid from
the process connector` to the interface.
TM
FOUNDATION Fieldbus (FF): An all-digital, serial, bi-directional communications
network in a plant or factory automation environment. It is an open architecture, developed
and administered by the Fieldbus FOUNDATION.
Guided Wave Radar (GWR): A method commonly used to measure levels of liquid and
solid materials. Low frequency microwave pulses are guided by a metal probe and reflected
off a surface to determine levels in tanks.
®
HART Communications Protocol: Highway Addressable Remote Transducer (HART) is a
digital industrial automation protocol that is modulated over legacy 4-20 mA analog
instrumentation wiring
Honeywell Experion: An advanced distributed control system (DCS) and innovative
software applications to improve users' business performance and ensures reliable
performance.
Honeywell Field Device Manager (FDM): A centralized asset management system for
remote configuration and maintenance of smart field devices based on HART, PROFIBUS
and Fieldbus FOUNDATION protocols.
Interface Measurement: Level measurements where to two liquids meet. For example, an
oil layer on top of water. Where the two meet is referred to as the interface level.
International Electrotechnical Commission Explosive Scheme (IECEx): IECEx
certification provides assurance that the strictest safety requirements of IEC International
Standards are met. Designed to facilitate the international trade of electrical equipment used
in explosive, hazardous environments.
Latching Mode: A parameter in the Level transmitter Advanced Display which allows for
the selection of the behavior of the Level transmitter in the event of a critical error. In this
mode, the transmitter wills stay in the critical error state until a user performs a hardware or
software reset.
Lower Range Value (LRV): A Basic configuration parameter which allows users to enter
the measuring value for which the analog output will be scaled to 4 mA.
Lower Product: The heavier liquid when two liquids exist in a vessel (e.g. water in an
oil/water measurement application).
Maintenance Mode: A mode that the transmitter supports to communicate to external
systems that it is not available for process measurement.
NAMUR NE 43: NAMUR is an international association of process instrumentation user
companies. NE 43 is a NAMUR recommendation to promote a standardization of the 4-
20mA signal level for failure information. Normal 2-wire transmitters use the 3.8 to 20.5mA
signal range for measurement information, with ≥21mA or ≤3.6mA to indicate diagnostic
failures.
National Pipe Thread (NPT): A U.S. standard for tapered threads used on threaded pipes
and fittings.
Echo Lost Timeout: This parameter allows adjusting the time when the GWR Transmitter
waits with reaction to echo loss.
Latching Mode: This parameter allows selecting the behavior of the GWR transmitter in
case of a critical error. If the Latching option is selected, the GWR transmitter will stay in the
critical error state until a user performs a hardware or software reset.
