Example 1 (Offset=0 as shipped from factory): Application calls for a 72-inch NPT coaxial probe in water with the bottom of the probe 10 inches above the bottom of the tank. The user wants the 4 mA point at 24 inches and the 20 mA point at 60 inches as referenced from the bottom of the probe. In applications in which it is desired to reference all measurements from the bottom of the vessel, the value of OFFSET should be changed to the distance between the bottom of the probe and the bottom of the vessel as shown in Example 2. Example 2: Application calls for a 72 inch NPT coaxial probe in water with the bottom of the probe 10 inches above the bottom of the tank. The user wants the 4 mA point at 24 inches and the 20 mA point at 60 inches as referenced from the bottom of the tank. When the Horizon transmitter is mounted in a chamber/bridle, it is usually desirable to configure the unit with the 4 mA (0%) point at the lower process connection and the 20 mA (100%) point at the upper process connection. In other words, the span is the center-to-center dimension. In this case a negative OFFSET needs to be entered. In doing so, all measurements are then referenced at a point up on the probe as shown in Example 3.

When connected to the control loop, the same system measurement readings shown on the transmitter are shown on the communicator. In addition, the communicator can be used to configure the transmitter. The HART communicator may need to be updated to include the Horizon software (Device Descriptors). Contact your local HART Service Center for additional information.

Example 3
A HART communicator can be operated from a remote location by connecting it to a remote junction or by connecting it directly to the terminal block in the electronics housing of the Horizon transmitter. HART uses the Bell 202 frequency shift key technique of high-frequency digital signals. It operates on the 4-20 mA loop and requires 250 Ω load resistance. A typical connection between a communicator and the Horizon transmitter is illustrated.

Reference Information
This section presents an overview of operating the Horizon Guided Wave Radar Level Transmitter as well as information on troubleshooting common problems, listings of agency approvals, lists of replacement parts, and detailed physical, functional, and performance specifications.
3.1
Description Horizon is a loop-powered two-wire, 24 VDC, level transmitter based on the concept of Guided Wave Radar. Guided Wave Radar (GWR) is a relatively new level measurement technology. The Horizon electronics are housed in a single compartment housing available in either cast aluminum or Valox.
3.2
Theory of Operation
3.2.1 Micropower Impulse Radar
GWR combines TDR (time domain reflectometry), ETS (equivalent time sampling) and modern low power circuitry. This synthesis of technologies brings to the level market a high-speed radar circuit (speed of light transmission) at a small fraction of the cost of conventional radar. The electromagnetic pulses are propagated via a waveguide that yields a system many times more efficient than through-air radar.
24 VDC, 4-20 mA Loop Powered
Transmit Pulse A reflection is developed off the liquid surface
Air
εr = 1
Media ε r > 1.7 A small amount of energy continues down the probe in a low dielectric fluid, e.g. hydrocarbon

57-603 Horizon Guided Wave Radar Transmitter
3.2.2 Time Domain Reflectometry (TDR)
TDR uses pulses of electromagnetic (EM) energy to measure distances or levels. When a pulse reaches a dielectric discontinuity (created by media surface), part of the energy is reflected. The greater the dielectric difference, the greater the amplitude (strength) of the reflection. Although TDR is relatively new to the industrial level measurement industry, it has been used in the telephone, computer, and power transmission industries for years. In these industries, it is used to successfully find wire or cable breaks and shorts. An EM pulse is sent through the wire traveling unimpeded until it finds a line break or short. A reflection is then returned from the break and a timing circuit pinpoints the location. In the Horizon transmitter, a waveguide with a characteristic impedance in air is used as a probe. When part of the probe is immersed in a material other than air, there is lower impedance due to the increase in the dielectric. When the EM pulse is sent down the probe and meets the dielectric discontinuity, a reflection is generated.
3.2.3 Equivalent Time Sampling (ETS)
ETS is used to measure the high speed, low power EM energy. ETS is a critical key in the application of TDR to vessel level measurement technology. The high speed EM energy (1000 ft/µs) is difficult to measure over short distances and at the resolution required in the process industry. ETS captures the EM signals in real time (nanoseconds) and reconstructs them in equivalent time (milliseconds), which is much easier to measure with today’s technology. ETS is accomplished by scanning the waveguide to collect thousands of samples. Approximately 8 scans are taken per second. 3.3 Troubleshooting The Horizon transmitter is designed and engineered for trouble-free operation over a wide range of operating conditions. Common transmitter problems are discussed in terms of their symptoms and recommended corrective actions. Information on how to handle material buildup on the probe is also provided in this section.
WARNING! Explosion hazard. Do not connect or disconnect equipment unless power has been switched off or the area is known to be non-hazardous.

3.3.1 Model 704 System Problems
Symptom LEVEL, % OUTPUT and LOOP values are all inaccurate Problem Basic configuration data is questionable Solution Reconfigure the Probe Model, Probe Length or Offset 1) Ensure the Level is accurate 2) Verify 4 mA and 20 mA Loop values Ensure proper Probe Model and Probe Length
LEVEL readings are repeatable but consistently high or low from actual by a fixed amount
Configuration data does not accurately match probe length or tank height Installation Variance
Adjust Level Trim Increase the Damping factor until the readings stabilize Check Fid Ticks (should be stable within ±10 counts) Select Fixed Threshold option
LEVEL, % OUTPUT and LOOP values fluctuate
Turbulence High Frequency connection
LEVEL, % OUTPUT and LOOP values all reading low vs. actual
Lower dielectric material over higher dielectric material, e.g., oil over water
Coating, clumping or buildup on probe Expected inaccuracies due to affect on pulse propagation Dense, water based foam Expected inaccuracies due to affect on pulse propagation Set POLL ADR to 0 if not using HART multi-drop Contact local HART service center for the latest DDs Check actual level. If probe is not flooded, Check for buildup or obstructions near top of probe. Select higher dielectric range or set sensitivity to Low 1) Increase DEADBAND 2) Decrease SENSITIVITY Possible obstruction in tank 1) Reduce SENSITIVITY until obstruction is ignored 2) Relocate probe away from obstruction Ensure transmitter connected securely to probe Adjust Level Trim
LEVEL reading on Display is correct but LOOP is stuck on 4 mA HART device only: handheld will only read Universal Commands Level Reading on Display is stuck at full scale, loop is stuck at 20.5 mA
Basic configuration data is questionable Most current Device Descriptors (DDs) are not installed in handheld Software believes probe is flooded (level near very top of probe)
LEVEL, % OUTPUT and LOOP values all at maximum level LEVEL, % OUTPUT and LOOP values all reading high vs. actual
Possible configuration Issue

3.3.3 Application Concerns
Film Coating
Bridging
There are numerous causes for application problems. Media buildup on the probe and stratification are covered here. Media buildup on the probe is not a problem in most cases–Horizon circuitry typically works very effectively. Media build-up should be viewed as two types–Film Coating and Bridging. A twin rod probe can be utilized when minor film coating is a possibility. • Continuous Film Coating The most typical coating problems occur when the media forms a continuous coating on the probe. Horizon will continue to measure effectively with a small degradation in performance. A problem can develop if the product begins to build up on the spacers that separate the probe elements. High dielectric media (e.g., water-based) will cause the greatest error. • Bridging Media that is viscous or solid enough to form a clog, or bridge, between the elements causes the greatest degradation in performance. High dielectric media (e.g., waterbased) will show as level at the location of the bridging.

3.3.3 Applications Concerns (cont.)
Low Dielectric Medium (e.g. oil)
• Stratification/Interface The standard Model 704 Horizon transmitter is designed to measure the first air/media interface it detects. However, a low dielectric over a high dielectric application can cause a measurement problem and cause the electronics to trigger on the high dielectric medium that lies beneath the low dielectric medium. Select the Fixed Threshold option to read the upper medium. Example: Oil over water.
