CAUTION!
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
INFORMATION!
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
This TDR level transmitter measures distance, level, mass and volume of liquids, pastes,
slurries, granulates and powders.
It can be installed on tanks, silos and open pits.

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
(2006), EN 61326-2-3 (2006). SIL-approved devices agree with EN 61326-3-1 (2008) and
EN 61326-3-2 (2008).
• SIL-approved devices agree with EN 61508 (2010).
All devices are based on the CE marking and meet the requirements of NAMUR Guideline NE 21,
NE 43, NE 53 and NE 107.
OPTIFLEX 2200 C/F
1.4 Electromagnetic compatibility
The device design agrees with European Standard EN 61326-1 when installed in metallic tanks.
You can install the device on open-air tanks and tanks that are not made of metal. Refer also to
the note that follows.
CAUTION!
If you install a device with a cable probe in a non-metallic tank or open-air pit, a strong
electromagnetic field near to the device can have an unwanted effect on the accuracy. Use a
device with a coaxial probe for this type of installation.
INFORMATION!
Device operation agrees with residential-class (class B) emissions and industrial-class for
immunity requirements if:
•
the device has a single or double probe (rod or cable probe) and is used in a closed tank made
of metal or
•
the device has a coaxial probe.

2.2 Device description
The TDR level transmitter is designed to measure the distance, level, mass and volume of
liquids, pastes, slurries, granulates and powders.
TDR level transmitters use a probe to guide a signal to the surface of the measured product. The
device has a large choice of probes. Thus, it can measure most products in difficult conditions.

3.5.2 General information for nozzles
CAUTION!
Follow these recommendations to make sure that the device measures correctly. They have an
effect on the performance of the device.
CAUTION!
Do not put the process connection near to the product inlet. If the product that enters the tank
touches the probe, the device will measure incorrectly.
INSTALLATION 3
Figure 3-5: Do not put the device near to a product inlet
1 The device is in the correct position.
2 The device is too near to the product inlet.
3 If it is not possible to put the device in the recommended position, install a deflector pipe.
Figure 3-6: How to prevent build up of product around the process connection
1 If product particles are likely to collect in holes, a nozzle is not recommended.
2 Attach the flange directly to the tank.
3 Use a threaded connection to attach the device directly to the tank.

For single cable and single rod probes:
Figure 3-7: Recommended nozzle dimensions for single rod and single cable probes
1 Recommended conditions: h ≤ d, where h is the height of the tank nozzle and d is the diameter of the tank nozzle.
2 The end of the nozzle must not have an extension into the tank. Do not install the device on a high nozzle.
CAUTION!
If the device is installed on a high nozzle, make sure that the probe does not touch the side of the
nozzle (attach the probe end, ...).

3.6.2 How to attach probes to the bottom of the tank
If the liquid is agitated or turbulent, you can attach the probe to the bottom of the tank. The
procedure to attach the probe depends on the type of probe used.
CAUTION!
Keep the probe straight.

CAUTION!
Installation requirements
•
The standpipe must be electrically conductive. If the standpipe is not made of metal, obey the
instructions for empty space around the probe. For more data, refer to General requirements
on page 22
The standpipe must be straight. There must be no changes in diameter from the device
•
process connection to the bottom of the standpipe.
•
The standpipe must be vertical.
•
Recommended surface roughness: <±0.1 mm / 0.004¨.
•
The bottom of the stilling well must be open.
•
Adjust the probe to the center of the standpipe.
•
Make sure that there are no deposits at the bottom of the standpipe which can cause
blockage of the process connections.
•
Make sure that there is liquid in the standpipe.

3.7 Installation recommendations for solids
3.7.1 Nozzles on conical silos
We recommend that you prepare the installation when the silo is empty.
DANGER!
Risk of electrostatic discharge (ESD): The device is resistant to electrostatic discharges of up to
30 kV, but it is the responsibility of the fitter and the user to prevent ESD.
CAUTION!
Install the device at the correct location to measure level correctly and prevent too much
bending and traction. If necessary, attach the probe to the bottom of the tank.
