1. The device is manufactured as one unit that includes the transmitter and antenna. 2. Remove any protective material from the antenna before installing. 3. Install the transmitter/antenna into the process connection. If threaded, tighten securely by hand using the housing for grip. Ensure there is no cross-threading and do not over tighten as this may cause damage to the plastic threads. 4. Adjust the beam position by turning the internal launcher adjustment (Figure 2). The internal launcher adjustment is numbered 1-18 that equates to 10-180 degrees of adjustment; 9 is the midpoint. The polarization pattern is parallel to the transmitter display when the adjustment mechanism is in the #11 position (factory default). After positioning the transmitter display, the launcher should be adjusted so the polarization pattern is parallel to a line tangent to the nearest tank wall (Figure 3). Do not optimize the Echo Strength at one level in the vessel. • Do not place insulating material around any part of the Radar transmitter including the antenna process connection.

Complete Installation
This section provides detailed procedures for properly installing, configuring, and, as needed, troubleshooting the R82 Radar Level Transmitter.
2.1
Unpacking Unpack the instrument carefully. Make sure all components have been removed from the packing material. Check all the contents against the packing slip and report any discrepancies to the factory. Before proceeding with the installation, do the following: • Inspect all components for damage. Report any damage to the carrier within 24 hours. • Make sure the nameplate model number on the transmitter agree with the packing slip and purchase order. • Record the model and serial numbers for future reference when ordering parts.
2.2
Electrostatic Discharge (ESD) Handling Procedure Magnetrol’s electronic instruments are manufactured to the highest quality standards. These instruments use electronic components that may be damaged by static electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge. Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap the board in aluminum foil. Do not place boards on foam packing materials. Use a grounding wrist strap when installing and removing circuit boards. A grounded workstation is recommended. Handle circuit boards only by the edges. Do not touch components or connector pins. Make sure that all electrical connections are completely made and none are partial or floating. Ground all equipment to a good, earth ground.

The chart at left shows the maximum measuring range (Distance) based on fundamental conditions of Dielectric, Distance and Turbulence. Maximum distance is calculated as Tank Height + Sensor Offset (see page 20). It is measured from the Sensor Reference Point (bottom of NPT thread, top of BSP thread or face of a flange).
2.3.3.2 Minimum Distance
10.0-100
Figure 7
If the liquid level is allowed onto the antenna, noise and media build-up drastically decrease reliable measurement. Liquid should not be allowed closer than 15 inches (380 mm) from the bottom of the antenna mounting threads (or face of hygienic flange). The distance from the end of the antenna varies depending on antenna chosen. See Figure 8.

2.3.3.3 Problematic Applications; GWR Alternative
• • • •
Some application concerns can be problematic for Radar. For these, Guided Wave Radar is recommended: Extremely low dielectric media (εr 10" (25 cm) 1/2 Radius
2.4 Mounting The R82 Radar transmitter can be mounted to a vessel using a variety of process connections. Generally, either a threaded or flanged connection is used.
2.4.1 Installing the Transmitter
•
• • •
Before installing, make sure: Process temperature, pressure, dielectric, turbulence and distance are within the antenna specifications for the installation. End of antenna is protected from bending or breaking. Insulating material is not placed around any part of the Radar transmitter including the antenna flange. Transmitter is being mounted in the optimal location. See following sections: Location, Beam Angle, Obstructions and Nozzles for specific information.
Figure 10
2.4.1.1 Location
Ideally, the Radar transmitter should be mounted providing an unobstructed signal path to the liquid surface where it should illuminate (with microwave energy) the largest, possible surface area. See Section 2.4.1.2, Beam Angle. Unavoidable obstacles will produce reflections that must be minimized during field configuration. See Section 2.6.5.1, Target Rejection. Mount in a location equal to 1⁄2 the radius of tank top. Do not mount in center of vessel nor closer than 10" (25 cm) from the tank wall.

2.4.1.2 Beam Angle
Ideally, the beam pattern should illuminate the maximum liquid surface with a minimum striking other objects in the vessel including the tank wall.
Figure 11 12
58-610 Model R82 Radar Transmitter
2.4.1.3 Obstructions
Almost any object that falls within the beam pattern will cause reflections that may be misinterpreted as a false liquid level. Although Model R82 has a powerful Echo Rejection routine, all possible precautions should be taken to minimize false target reflections with proper installation and orientation. See Figure 12.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” which will adversely affect measurement. Two Antenna extension lengths are offered to allow the R82 transmitter to work reliably in a variety of nozzles. The Minimum Blocking Distance of 15" (380 mm) is always measured from the bottom of the threads or face of the flange. The related distance as measured from the end of the antenna varies depending on the antenna extension chosen. See Figure 13. The narrow beam width of the 26 GHz, R82 does allow mounting so that the antenna can be recessed inside the nozzle. Optimally, the recessed dimension should never exceed 2× the nozzle diameter. See Figure 13
NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo Rejection is run to eliminate any possibility of false reflections.
