HORIZON™ 703 Guided Wave Radar Level Transmitter DESCRIPTION The Horizon® 703 is a cost effective loop-powered, 24 V DC liquid-level transmitter based upon the revolutionary Guided Wave Radar (GWR) technology. The electronics of the Horizon® 703 is integral mount on the GWR probe and allows local calibration via a 3 pushbutton keypad. The Horizon® 703 electronics are compatible with different types of GWR probes each encompassing different application challenges (coaxial, single rod or twin rod types). The aluminium or Valox® housing can be removed for service under process conditions. F E AT U R E S Measures «REAL LEVEL» Horizon 703 with coaxial GWR probe * “REAL LEVEL”, measurement not affected by changing media variables eg. dielectrics, pressure, density, pH, viscosity, ... * Easy calibration via 3 pushbutton / 3 LED's user interface. * LED identification for - calibration / normal run mode - instrument failure, up to 5 different messages. * Only requires a small level variation to calibrate 4 and 20 mA setpoints. * Two-wire, intrinsically safe loop powered level transmitter. ® * Valox or cast aluminium housing options. * Max process temperature: 150 °C (300 °F). * Max process pressure: 70 bar (1000 psig). * Integral mount electronics. Horizon 703 with twin rod GWR probe Horizon 703 with sanitary CIP/SIP GWR probe 3 pushbutton keypad with LED’s A P P L I C AT I O N S 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: Almost 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.

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. Initial Pulse Reflected Pulse Air εr = 1 Liquid εr > 1.7 Transmitted Pulse Worldwide level and flow solutions 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, twin rod and single rod are the 3 basic configurations used today; each with specific strengths and weaknesses. COAXIAL TYPE GWR PROBE TWIN ROD TYPE GWR PROBE SINGLE ROD TYPE GWR PROBE signal propagation signal propagation signal propagation end view end view side view Ideally suited for: - media ≥ 1,7 - mounting in by-pass cages - most efficient GWR probe Ideally suited for: - media ≥ 2,5 - allows moderate build up (viscosity up to 1500 cP) Ideally suited for: - media ≥ 10 - handles very viscous media (viscosity up to 10.000 cP) Beware of: - clogging / buid up inside coaxial tube (max 500 cP) Beware of: - bridging build up between the two rods Beware of: - mounting considerations, see page 5.

Turbulence The bottom of the probe should be stabilized if turbulence will cause a deflection of more than 75 mm at 3 m of length. The probe should not make contact with a metal tank. A TFE bottom spacer (P/N 089-9114-001) for metal single rod GWR probes is optional. 3. Metallic (conductive) obstructions in tank. Distance to probe < 150 mm (6") 2. Nozzles: do not restrict performance by ensuring the following: 1. Nozzle must be 50 mm (2") or larger diameter. 2. Nozzle inside diameter (A) should be ≥ to nozzle height (B). If this is not the case, it is recommended to relocate the GWR probe or to consider a dual element probe. A > 150 mm (6") > 300 mm (12") > 450 mm (18") Acceptable objects Continuous, smooth, parallel, conductive surface (e.g. metal tank wall); probe should not touch tank wall < 1"/DN25 diameter pipe and beams, ladder rungs < 3"/DN80 diameter pipe and beams, concrete walls All remaining objects 4. Non-metallic vessels: 1. Flange (metal) mounting is recommended for optimum performance. 2. Mount probe more than 450 mm (18") from vesselwall. B Pipe reducers should not be used Correct installation High level shutdown / Overfill protection Use the Horizon GWR probes only for in-tank mounting. 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 7MA and 300 mm (12") for 7MF/7MB probes below the process connection. This may include utilizing a nozzle or spool piece to raise the probe. Consult factory for further information.
