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.

OPTIWAVE 7300 C

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.
