HORIZON™ 704
Guided Wave Radar
Level Transmitter
DESCRIPTION
The Horizon® 704 is a loop-powered, 24 V DC liquid-level
transmitter based on the revolutionary Guided Wave Radar
(GWR) technology. The electronics of the Horizon® 704 is
integral mount on the GWR probe and allows local configuration via a 3 pushbutton keypad / LCD screen. The
Horizon® 704 electronics are compatible with different types
of GWR probes each encompassing different application
challenges (coaxial or twin rod types). The aluminium or
Lexan® housing can be removed for service under process
conditions.

F E AT U R E S
* “REAL LEVEL”, measurement not affected by changing
media variables eg. dielectrics, pressure, density, pH, viscosity, ...
* Easy bench configuration - no need for level simulation.
* 2-line x 8-character LCD / 3-pushbutton keypad or blind
transmitter.
* Two-wire, intrinsically safe loop powered level transmitter.
* Housing can be easily removed without depressurizing
the vessel.
®
®
* HART /AMS digital communication.
* Max process temperature: 200 °C (400 °F).
* Max process pressure: 70 bar (1000 psi).
* 4-20 mA output (meets NAMUR NE 43).
* Integral mount electronics.
MEDIA: Liquids or slurries; hydrocarbons to water-based
media (dielectric 1,7 - 100).
VESSELS: Most process or storage vessels up to rated
probe temperature and pressure.
CONDITIONS: All level measurement and control applications
including process conditions exhibiting visible vapors, foam,
coating / build up, surface agitation, turbulence and varying
dielectric media or specific gravity.

TECHNOLOGY
Horizon Guided Wave Radar is based upon the technology
of TDR (Time Domain Reflectometry). TDR utilizes pulses
of electromagnetic energy, which are transmitted down a
probe. When a pulse reaches a liquid surface that has a
higher dielectric than the air/vapor in which it is travelling,
the pulse is reflected. An ultra high-speed timing circuit precisely measures the transit time and provides an accurate
measure of the liquid level.

PROBE OVERVIEW
Choosing the proper Guided Wave Radar (GWR) probe is the most important decision in the application process. The probe
configuration establishes fundamental performance characteristics. Coaxial and twin rod are the 2 basic configurations used
today; each with specific strengths and weaknesses.
COAXIAL TYPE GWR PROBE
signal propagation
Ideally suited for:
- media ≥ 1,7
- mounting in by-pass cages
- most efficient GWR probe
end view
Beware of:
- clogging / buid up inside coaxial tube (max 500 cP)
2
TWIN ROD TYPE GWR PROBE
signal propagation
end view
Ideally suited for:
- media ≥ 2,5
- allows moderate build up (viscosity up to 1500 cP)
Beware of:
- bridging build up between the two rods
A complete measuring system consists of:

High level shutdown /
Overfill protection
Special consideration is necessary in any
application where guided wave radar is to
be used for high level shutdown / overfill
protection. To ensure proper measurement, the guided wave radar probe should
be installed so the maximum overfill level is
a minimum of 150 mm (6") (for 7MB only)
below the process connection. This may
include utilizing a nozzle or spool piece to
raise the probe. No special precautions are
required for the 7MR probe.
