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 adjustment of the time that the GWR Transmitter waits
after echo loss before producing a critical fault alarm.
Latching Mode: This parameter allows the selection of the behavior of the GWR transmitter in the
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. This parameter is only relevant to
HART transmitters.
Operating Range: The range of conditions in which the transmitter is designed to operate.
PACTWare: A software application for instruments that is based on FDT technology. It can be used
to load and run a manufacturer's DTM for a specific instrument.
