1.3 Certification
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
In accordance with the commitment to customer service and safety, the device described in this document meets the following safety requirements:
•Electromagnetic Compatibility (EMC) Directive 2004/108/EC in conjunction with EN 61326-1 (2013).
•Radio Equipment and Telecommunications Terminal Equipment (R & TTE) Directive 1999/05/EC in conjunction with ETSI EN 302 372 (2006). For more data, refer to European Union (EU) on page 9.
•Low-Voltage Directive 2006/95/EC in conjunction with EN 61010-1 (2001).
All devices are based on the CE marking and meet the requirements of NAMUR Guideline NE 21 and NE 43.
1.4 Electromagnetic compatibility
The device design agrees with European Standard EN 61326-1.
You can install the device on open-air tanks and tanks that are not made of metal. But refer to Radio approvals on page 9. This agrees with Immunity and Emissions requirements for industrial environments.
INFORMATION!
Device operation agrees with residential-class (class B) immunity and emissions requirements if the antenna is used in a closed tank made of metal.

2.2 Device description
This device is a 24 GHz FMCW-radar level transmitter. It is a non-contact technology and is 2- wire loop-powered. It is designed to measure the distance, level, mass, volume and reflectivity of liquids, pastes and slurries.
Radar level transmitters use an antenna to guide a signal to the surface of the measured product. The device has many antennas available. Thus, it can measure most products even in difficult conditions. Also refer to Technical data on page 92.
The device has a set-up wizard, fully-potted electronic circuit boards and online help functions.
You usually will not need this Handbook to install, set up and operate the device.
If it is ordered with the applicable options, it can be certified for use in hazardous areas.
These output options are available:
•1 output: 4...20 mA (HART)
•2 outputs: 4...20 mA (HART) + 4...20 mA
These accessories are available:
•Stainless steel weather protection.
•RS232 / HART® converter (VIATOR).
•USB / HART® converter.
INFORMATION!
For more data on accessories, refer to List of accessories on page 130.

Stilling wells - general notes
Installation in tanks containing one liquid and foam
•Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
•Remove the burr from the hole.
Installation in tanks containing one liquid or more without foam
•Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.
•Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the tank).
i These holes help the liquid to move freely between the stilling well and the tank.
• Remove the burr from the hole.
Stilling wells: floating roofs
If the device must be installed on a tank with a floating roof, install it in a stilling well.

Stilling wells: horizontal cylindrical tanks
We recommend that you install the device in a stilling well if the device:
•is for a horizontal cylindrical tank,
•is in a metallic tank,
•measures a product with a high dielectric constant and
•is on the centerline of the tank.
Figure 3-11: Horizontal cylindrical tanks
1The device is installed without a stilling well. There are multiple reflections. Refer to the CAUTION! that follows.
2The device is installed in a stilling well and measures correctly.
CAUTION!
If the device is installed in horizontal cylindrical tank that contains a high dielectric constant liquid without a stilling well, do not put it on the tank centerline. This will cause multiple reflections and the device will not measure accurately. Use the Multiple Reflections function in
Supervisor > Advanced Setup > Installation Setup to keep the effects of multiple reflections to a minimum. For more data, refer to Function description on page 57 (C. Advanced Setup).

Bypass chambers
Installation next to tanks containing one liquid and foam
•The top process connection of the bypass chamber must be above the maximum level of liquid.
•The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.
Installation next to tanks containing more than one liquid
•The top process connection of the bypass chamber must be above the maximum level of liquid.
•The bottom process connection of the bypass chamber must be below the lowest measured level of liquid.
•Additional process connections are necessary for the liquids to circulate freely along the length of the bypass chamber.
