Krohne Radar level transmitters / OPTIWAVE 5200 C

VF5041B0TH0H1A1AB16000000 - (Level Transmitter for liquids in storage
and process applications)

The Krohne Optiwave 5200 measures liquid and paste levels using Frequency Modulated Continuous Wave (FMCW) radar technology. It works by emitting a continuously increasing-frequency radar signal that reflects off the product surface. The time delay between the transmitted and received signals, or the resulting frequency difference (Δf), is directly proportional to the distance to the surface, which is then used to calculate the level.

FMCW Radar Principle

1. Signal Transmission: The Optiwave 5200 emits a high-frequency radar signal from its antenna. Frequency
2. Sweep: The frequency of the transmitted signal increases linearly over a short period (the frequency sweep).
3. Reflection: The signal travels to the product's surface, reflects, and returns to the antenna. Signal Reception: The device receives the reflected signal after a specific time delay. Frequency Difference (Δf): A difference (Δf) is calculated between the instantaneously transmitted frequency and the received frequency. Distance
4. Calculation: This frequency difference (Δf) is directly proportional to the distance (d) to the product surface, calculated as \(t=2d/c\), where c is the speed of light.
5. Signal Processing: A Fast Fourier Transform (FFT) is performed to convert the frequency difference into a frequency spectrum, allowing the distance to the product to be determined.
6. Level Determination: The distance is subtracted from the total tank height to derive the measured level.

Key Features and Applications

• Non-Contact Measurement: The Optiwave 5200 is a non-contact radar level transmitter, making it ideal for various materials including corrosive products.
• Applications: It measures the distance, level, and volume of liquids, pastes, and slurries in storage and process tanks.
• Modular Design: The device features a modular design with a quick coupling system for flexible installation in different positions.
• Process Conditions: It is designed to operate under extreme conditions, such as high temperatures and pressures, and in corrosive environments.

Krohne Radar level transmitters / OPTIWAVE 7500 C

VFDF40W500211480240MC7000 - (Level Transmitter for liquids in
narrow tanks with internal obstructions)

The OPTIWAVE 7500 works by using Frequency Modulated Continuous Wave (FMCW) radar technology to measure the non-contact, continuous level of liquids in challenging narrow tanks with internal obstructions like heating coils or agitators. It transmits a radar signal, which reflects off the liquid surface and is received back by the sensor. The frequency difference between the transmitted and received signals is proportional to the distance to the liquid, allowing for accurate level calculation

How FMCW Radar Works

1. Transmission: The OPTIWAVE 7500 transmits a continuous radar signal whose frequency is constantly changing (modulated).
2. Reflection: This signal travels to the liquid surface, reflects off it, and returns to the sensor.
3. Reception: The sensor receives the reflected signal.
4. Frequency Difference: Since the reflected signal has been traveling for a certain time, its frequency is different from the transmitted signal at that instant.
5. Distance Calculation: The device measures this frequency difference, which is directly proportional to the time the signal took to travel to the liquid and back.
6. Level Measurement: By calculating this time-of-flight, the sensor determines the distance to the liquid surface, providing a continuous and accurate level measurement.

Key Features and Applications

• Narrow Beam Angle: The 80 GHz frequency of the OPTIWAVE 7500 results in a very narrow beam angle, which is ideal for avoiding obstructions like internal tank components.
• Non-Contact Measurement: It measures the liquid level without physical contact, preventing contamination and wear.
• Tank Bottom Management (TBM): This feature uses dedicated algorithms to filter out false reflections, ensuring reliable measurements even when the tank is nearly empty or has a complex bottom geometry.
• Flush-Mounted Lens Antenna: The PEEK and PTFE lens antenna is insensitive to build-up and corrosion and is flush-mounted, minimizing intrusion into the tank.
• Challenging Conditions: The transmitter is suitable for narrow tanks, long nozzles, corrosive liquids, and high temperatures and pressures.
• Internal Obstructions: Its design makes it effective in tanks with internal features such as agitators or heating coils.
