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).

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 rod or 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 DEVICE DESCRIPTION

OPTIFLEX 1300 C

2.2 Device description

The TDR level transmitter is designed to measure the distance, level, interface, 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. For more data, refer to Technical data on page 127.

The device has a set-up wizard, fully-potted electronic sub-assemblies and online help functions. You usually will not need this document to install, set up and operate the device.

You can order these accessories:

•Stainless steel weather protection.

•RS232 / HART® converter (VIATOR).

•USB / HART® converter (VIATOR).

•ESD protection (30 kV).

•Metaglas® dual process sealing system for dangerous products.

INFORMATION!

For more data on accessories, refer to List of accessories on page 182.

If the device is supplied with an FKM/FPM gasket, there is no symbol on the side of the process connection.

WARNING!

• If the display screen glass is broken, do not touch.

•If the device has to measure the level of dangerous products (ammonia etc.), we recommend that the device has the Metaglas® option.

•If the device has to measure the level of products where there is a risk of electrostatic discharge, we recommend that the device has the ESD (electrostatic discharge) protection option.

3.5.2 General information for nozzles

CAUTION!

Follow these recommendations to make sure that the device measures correctly.

Figure 3-5: Recommended nozzle dimensions for single rod and single cable probes

1Recommended conditions: h ≤ d, where h is the height of the tank nozzle and d is the diameter of the tank nozzle.

2The 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, ...). We recommend that you use a coaxial probe (this solution is applicable only to liquids).

INFORMATION!

It is possible to measure in these conditions with a minimum top dead zone. Use the snapshot function to filter the parasite signals from long nozzles. For more data, refer to How to use the snapshot function to filter parasitic signals on page 96.

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.

1The device is in the correct position.

2The device is too near to the product inlet.

3If it is not possible to put the device in the recommended position, install a deflector pipe.

Figure 3-8: How to prevent build-up of product around the process connection

1If product particles are likely to collect in holes, a nozzle is not recommended.

2Attach the flange directly to the tank.

3Use a threaded connection to attach the device directly to the tank.

2If there are too many objects in the tank, install a bypass chamber or stilling well.

3Keep the probe straight. If the probe is too long, shorten the probe length. Make sure that the device is configured with the new probe length. For more data on the procedure, refer to How to decrease the length of probes on page 98.

4Empty space. Refer to the table that follows.

INFORMATION!

If the device has to measure the level of dangerous products (ammonia etc.), we recommend that you use a device with the Metaglas® option.

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.

Double rod Ø8 mm / 0.32¨

Figure 3-11: How to attach a double rod probe to keep it straight

• Weld a tube with an internal diameter of 28...30 mm / 1.1...1.2¨ to the bottom of the tank. i Make sure the tube aligns with the process connection at the top of the tank.

•Lower the probe into the tank.

•Put the end of the probe into the tube.

Double cable Ø4 mm / 0.16¨

4If you chose a chuck to anchor the probe, we recommend that you fit a ferrule (metal sheath - not supplied) at the bottom of the loop to prevent cable wear

The probe counterweight has a hole with an M8 internal thread. The other probe end options are given in the illustration.

CAUTION!

If your device has a chuck, you must make the device recalculate the probe length. For the procedure, refer to How to decrease the length of probes on page 98. If the device does not recalculate the probe length, it is possible that the device will not measure correctly.

3.6.3 Standpipes

Use a standpipe if:

•There is highly conductive foam in the tank.

•The liquid is very turbulent or agitated.

•There are too many other objects in the tank.

•The device is measuring a liquid (petro-chemicals) in a tank with a floating roof.

1Stilling well

2Bypass chamber

3Air circulation hole

4Level of the liquid

CAUTION!

Installation requirements

•The standpipe must be electrically conductive.

•The standpipe must be straight. There must be no sudden changes in internal diameter greater than 1 mm / 0.04¨.

•The standpipe must be vertical.

•Recommended surface roughness: <±0.1 mm / 0.004¨.

•Stilling well only: 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.

•Make sure that there is liquid in the standpipe.

INFORMATION!

Standpipes are not necessary for devices with coaxial probes. But if there is a sudden change in diameter in the standpipe, we recommend that you install a device with a coaxial probe.

Installation in tanks containing one liquid and foam

•Drill a pressure equalization hole in the stilling well above the maximum level.

•Deburr the hole.

•If the probe has a counterweight, make sure that there is enough space between the counterweight and the wall of the stilling well.

Installation in tanks containing more than one liquid

•Drill a pressure equalization hole in the stilling well above the maximum level of the top liquid.

•Drill more holes along the length of the stilling well. Distance between holes ≥ 25 mm / 1¨ (depends on the minimum layer to be measured)

i These holes help the liquids to move freely.

•Deburr the holes.

•If the probe has a counterweight, make sure that there is enough space between the counterweight and the wall of the stilling well.
