1.1 The radar solution for liquids

This device is a non-contact Radar (FMCW) Level Meter for distance, level, volume and mass measurement of liquids, pastes and slurries. It gives a stabler measurement than pulse radar and is well suited to agitated process conditions. The device can operate at very low and very high process temperatures as long as the process connection temperature limits are observed.

1.2 Applications

1. Level measurement of liquids in storage tanks

2. Level measurement of liquids in process tanks

PRODUCT FEATURES

The level transmitter can measure the level of a wide range of liquid products on a large variety of installations, including LPG and LNG tanks. It does not require calibration or commissioning when installed. It can measure any liquid within the stated pressure and temperature range, and distances up to 80 m / 260 ft.

The level transmitter can measure level accurately in agitated conditions, such as near to vortexes caused by agitators, and also where foam is present.

3. Wave height measurement

The fast motion software option permits the device to measure 5 times per second. The device can follow fast changes in the height of surface waves in oceans and lakes. This software also permits the device to monitor torpedo ladle filling operations in steel mills.

PRODUCT FEATURES

4. Open channel metering or flow

5. Measurement of liquids in a bypass chamber

OPTIWAVE 7300 C

The level transmitter can measure level in an open channel and convert this measurement into flow values if the characteristics of the channel are known. This solution is the high-end alternative to ultrasonic and hydrostatic pressure transmitters.

If the tank is full of obstructions such as agitators and reinforcements, we recommend installing the radar level transmitter in a bypass chamber or a stilling well. This solution is also available from us under the name BM 26 W. The BM 26 W combines the BM 26 A with the radar level transmitter. The device includes a permanent, local indication without a power supply. Please refer to the BM 26 W documentation for further information.

6. Measurement of corrosive liquids with a Drop antenna

The Drop antenna option combines a relatively small radar beam for more precise measurement and a shape that avoids product build-up. If the tank contains corrosive liquids such as acids and alkaline

solutions, we recommend the DN80 / 3¨ Drop

antenna with the PTFE or PP flange plate protection option.

7. Measurement of liquids with a Hygienic antenna

The Hygienic antenna option is made of materials that agree with FDA regulations. It is suitable for level measurement in processes that require hygienic equipment (such as the food, beverage and pharmaceutical industries).

1.3 Measuring principle

A radar signal is emitted via an antenna, reflected from the product surface and received after a time t. The radar principle used is FMCW (Frequency Modulated Continuous Wave).

The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected on the measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product.

For further signal processing the difference Δf is calculated from the actual transmitted frequency and the received frequency. The difference is directly proportional to the distance. A large frequency difference corresponds to a large distance and vice versa. The frequency difference Δf is transformed via a Fourier transformation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum. The level results from the difference between tank height and measuring distance.

3.1 Intended use

This radar level transmitter measures distance, level, mass, volume and reflectivity of liquids, pastes and slurries.

It can be installed on tanks, reactors and open channels.

3.2 Pre-installation requirements

Obey the precautions that follow to make sure that the device is correctly installed.

• Make sure that there is sufficient space on all sides.

• Protect the signal converter from direct sunlight. If necessary, install the weather protection

accessory.

• Do not subject the signal converter to heavy vibrations. The devices are tested for vibration

and agree with EN 50178 and IEC 60068-2-6.

Maximum distance of nozzle from the tank wall : 1/3 × tank diameter

6 Minimum distance of nozzle from the tank wall : 1/10 × tank height

Maximum distance of nozzle from the tank wall : 1/3 × tank diameter

If possible, do not install a nozzle on the tank centerline.

Do not put the device near to the product inlet. If the product that enters the tank touches the antenna, the device will measure incorrectly. If the product fills the tank directly below the antenna, the device will also measure incorrectly.

3.4.2 Standpipes (stilling wells and bypass chambers)

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.

• The device is installed in a horizontal cylindrical tank (refer to the end of this section)

INSTALLATION

Figure 3-6: Installation recommendations for standpipes (stilling wells and bypass chambers)

1 A stilling well solution 2 A bypass chamber solution 3 Air circulation hole 4 Level of the liquid

•

The standpipe must be electrically conductive.

•

The inside diameter of the standpipe must not be more than 5 mm / 0.2¨ over the diameter of the antenna (for a high-dielectric constant liquid).

•

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.

•

Make sure that there are no deposits at the bottom of the standpipe.

•

Make sure that there is liquid in the standpipe.

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.

INSTALLATION

Figure 3-8: Horizontal cylindrical tanks

1 The device is installed without a stilling well. There are multiple reflections. Refer to the CAUTION! that follows. 2 The device is installed in a stilling well and measures correctly.

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 Supervisor > Advanced Setup > Installation Setup

4.1 Safety instructions

All work on the electrical connections may only be carried out with the power disconnected. Take note of the voltage data on the nameplate!

Observe the national regulations for electrical installations!

For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.

Observe without fail the local occupational health and safety regulations. Any work done on the electrical components of the measuring device may only be carried out by properly trained specialists.

Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate.

4.3 Protection category

The device fulfils all requirements per protection category IP66 / IP67. It also fulfils all requirements per NEMA type 4X (housing) and type 6P (antenna).

Make sure that the cable gland is watertight.

Figure 4-4: How to make the installation agree with protection category IP 67

• Make sure that the gaskets are not damaged.

• Make sure that the electrical cables are not damaged.

• Make sure that the electrical cables agree with the national electrical code.

• The cables are in a loop in front of the device 1 so water does not go into the housing.

• Tighten the cable feedthroughs 2.

• Close unused cable feedthroughs with dummy plugs 3.
