4 Eclipse is a two wire, loop powered, 24vDC level transmitter based on Guided Wave Radar and offered with a 2 line x 8 character display and/or HART communications.

5 How Does It Work? Pulses of high frequency energy are sent down a probe (wave guide) and timing circuitry measures the reflection of the signal off the surface of the process The higher the dielectric, the stronger the return signal

7 TDR Circuitry Digital Circuitry Display Keypad Explosion-proof and Watertight feedthrough Terminal Connection board Electronic Nameplate Universal High Frequency Connector Wiring Compartment Electronic Compartment

8 Advantages Compact and lightweight Loop-powered for ease of installation Top-mounted with with quick connect and disconnect feature Ergonomic and functional dual-chamber enclosures rotate 360º HART and AMS capable 13 probes (coaxial, twin-rod, single rod)

9 Advantages Challenging applications that include shifting and changing media High temperature & high pressure applications Menu driven user interface with simple straightforward set-up and configuration International hazardous location approvals Proven performance with more than 12000 units installed worldwide

10 Where to apply Challenging applications (saturated steam, 100% full vessels or chambers, extremes in temperature and pressure; dielectric media as low as 1.4; shifting gravity and dielectric media Wide probe selection accomodates a broad range of media – from solvents to viscous Bunker C fuel oils and coating media such as latex paints

11 Where to apply Hazardous area service in Power, Offshore/Onshore production, Refining, Chemicals and Petrochemicals Tanks and vessels up to 20 feet high (705) and 50 feet high (708) Interface measurement up to 12 feet (707)

12 Where to apply Applications where traditional instruments have not fulfilled user expectations for reliability or performance (i.e. DP or RF transmitters, Torque Tube transmitters/controllers, Magnetostrictive devices)

13 Where to exercise caution Vessel or media are at or near the maximum capabilities of Eclipse Caustic or acidic media may present corrosion-related problems for the probe Probe may encounter bridging due to dirty or highly viscous media Excessive vortices or agitation that may damage the probe Boiling and/or flashing may occur

14 Where NOT to apply Eclipse maximum operating temperatures, pressures or specifications are exceeded Media with dielectric < 1.4 Tank heights greater than 50 feet Headroom does not permit safe installation of a rigid probe Interface applications where upper and lower dielectric media are out of range Top medium is higher dielectric than lower medium (707 only)

15 Where to use PULSAR instead Medium’s viscosity exceeds selected probe’s capabilities Diminished headroom only allows for use of radar transmitter with small antenna Long probes are difficult or unsafe to install End-user prefers non-contact devices Corrosion or viscosity conditions favor specification of non-contact device

17 Horizon Model 703 Cost effective blind transmitter in a single-compartment housing Pushbutton Calibration with a 3-pushbutton, 3 LED user interface Level movement or “Level- simulation” required for calibration

18 Horizon Model 704 Intermediate transmitter in a single-compartment housing Optional LCD and HART output No level movement required for configuration

19 Advantages Stripped-down Eclipse versions for simple applications 703 simplest version, very economical 704 same display as Eclipse Compact, lightweight and affordable Loop-powered for ease of installation Broad range of industry segments and applications

20 Advantages Choice of plastic or aluminum single compartment enclosure Coaxial, twin-rod and single rod probes up to 16 feet General purpose areas in clean industry applications where XP is not needed (Valox housing versions) Worldwide safety approvals

21 Where to apply 703: OEM, water-wastewater and general non-hazardous locations 704: Hygiene-intensive industries where 3-A authorized probe, Tri-Clamp fiting and a plastic housing make easy CIP while eliminating an oxydation threat Either: Tanks, open channels, pits, sumps or wet wells up to 16 feet tall Applications within unit’s specifications

22 Where to exercise caution Vessel or media are at or near the maximum capabilities of Horizon Caustic or acidic media may present corrosion-related problems for the probe Probe may encounter bridging due to dirty or highly viscous media Excessive vortices or agitation that may damage the probe Boiling and/or flashing may occur

23 Where NOT to apply Maximum operating temperatures, pressures or specifications are exceeded Media with dielectric < 1.7 Tank heights greater than 16 feet Headroom does not permit safe installation of a rigid probe

24 Where to use PULSAR instead Medium’s viscosity exceeds selected probe’s capabilities Diminished headroom only allows for use of radar transmitter with small antenna Long probes are difficult or unsafe to install End-user prefers non-contact devices Corrosion or viscosity conditions favor specification of non-contact device

30 Antenna Offering 400F (204C) 200F (93C) 400F (204C) TFE Polypropylene 4” 6” 675psig (46.5bar) 750psig (51.7bar) 675psig (46.5bar) Min. Dielectric 2.0 1.7

31 Advantages Compact, lightweight and affordable Loop-powered for ease of installation Non-contact technology, top-mounted with quick connect/disconnect Unaffected by fumes and vapors above the process level Tolerates turbulence and light to medium density foam

32 Quick-Start procedures simplify set-up and start-up Dual compartments for convenient wiring and display Changing dielectrics or conductivity do not affect measurement accuracy Advanced signal processing extracts true level from false reflections Avail. 4” & 6” metal horn and dielectric rod antennas (polypropylene and Teflon) Advantages

33 Where to apply Where measuring requirements exceed capabilities of Eclipse GWR Where Pulsar is more cost effective due to the probe length of GWR Vessels where there is insufficient headroom for a probe instrument When user prefers non-contact devices Highly viscous, coating media which could cause bridging of GWR probes

34 Where to exercise cautions Vessel contents may reach 100% full point, or within 2” of the antenna Very low dielectric media combined with very long measurement ranges Vessels containing low dielectric media which normally operate at very low level Tanks with internal obstacles, or where severe turbulence or foam exists Vessels operating at or near the maximum recommended operating conditions

35 Where NOT to apply Where the maximum operating specifications are exceeded Dielectrics below 1.7 for horn antennas or 2.0 for dielectric rods Acids, corrosives or caustics incompatible with antennas or process seal/connections Extreme turbulence, excessive foam, vortices or rollover process conditions Excessive product build-up on antenna Standpipes and stillwells

36 Where to use GWR instead Excessive foam is present Dielectrics below 1.7 Low dielectric media (1.7<  <2.0) combined with very low product levels Extremely short measuring ranges T operating > 400ºF P operating > 750 psig @ +70ºF

37 Where to use GWR instead Saturated steam applications (deaerators or steam drums) Overfill conditions (applications require 100% of total capacity) Sanitary applications requiring 3-A Authorization

38 The Most Potent Combination in the Level Measurement Industry!
