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 also measure level and interface of liquids at the same time.

It can be installed on tanks, silos and open pits.

INSTALLATION 3

Figure 3-4: Pressure and temperature ranges

1 Process connection temperature

The process connection temperature must stay in the temperature range of the gasket material unless the device is a High-Temperature version. Refer to the table "Temperature ranges for gaskets" that follows and to "Technical data" on page 130. Ex devices: see supplementary operating instructions

2 Ambient temperature for operation of the display

-20...+60°C / -5...+140°F If the ambient temperature is not between these limits, the display screen switches off automatically

3 Ambient temperature

Non-Ex devices: -40...+80°C / -40...+176°F Ex devices: see supplementary operating instructions

4 Process pressure

Refer to the table "Process pressure limits" that follows and "Pressure/temperature table for probe selection" on page 136.

WARNING!

The process connection temperature range must agree with the temperature limits of the gasket material. The operating pressure range is subject to the process connection used and the flange temperature.

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

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.

INSTALLATION 3

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

3 INSTALLATION

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.

OPTIFLEX 1300 C

Figure 3-7: 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 3-8: 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.

INFORMATION!

If your device has a coaxial probe, you can ignore these installation recommendations.

CAUTION!

Install coaxial probes in clean liquids that are not too viscous.

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.

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.

OPTIFLEX 1300 C

Figure 3-17: Basic installation recommendations for standpipes (stilling wells and bypass chambers)

1 Stilling well 2 Bypass chamber 3 Air circulation hole 4 Level 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.

Floating roofs

If the device is for a tank with a floating roof, install it in a stilling well.
