Overview

The Xiamen Qunchuang QCT high-frequency 80G radar level gauge belongs to the universal radar level gauge. It is a measuring instrument based on the time travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses that propagate at the speed of light in space. When the pulses encounter the surface of the material, they are reflected back and received by the receiver inside the instrument, which converts the distance signal into a level signal.

Product Details

Xiamen Qunchuang QCT High Frequency 80G Radar Liquid Level Gauge

1、 Technical features

High frequency and high precision: The working frequency reaches 76-81GHz, the wavelength is only 3.75mm (millimeter wave band), the resolution can reach 1mm, and the measurement accuracy is ± 1mm. The short wavelength makes it highly penetrable to dust and steam, especially suitable for measuring solid particles or low dielectric constant media.

Shortwave beam angle and small blind spot: The antenna beam angle is only 3 °, energy is concentrated, and the blind spot can be as low as 0.07m (some models), reducing installation environment interference.

Wide range and strong adaptability: The maximum range is up to 120m (such as LWRD80xC model), supporting high temperature environments of -40~500 ℃ and high pressure environments of -0.1~40MPa. Corrosion resistant materials (such as PTFE antenna) can be customized.

Diversified output and installation: Supports 4-20mA/HART/RS485 signal output, provides various installation methods such as flanges and threads, and is suitable for tanks in industries such as petroleum, chemical, and power.

2、 Application Fields

Petrochemical industry: tank level monitoring, high-pressure reactor measurement.

Food and pharmaceuticals: The hygienic design meets the requirements of a sterile environment and is used for raw material storage.

Water treatment: Monitor the liquid level of reservoirs and sedimentation tanks, and support highly corrosive media.

Metallurgy and mining: resistant to high temperature dust environment, measuring the liquid level of slurry and molten metal.

3、 Installation precautions

Vertically align with the target to avoid the beam being obstructed by container walls or obstacles.

Stay away from the feed inlet to prevent false echo interference.

Minimum installation distance: At least 20cm away from the tank wall, the conical tank needs to ensure that the beam is directly directed at the bottom of the tank.

4、 Comparison with 26G radar level gauge

Higher accuracy: 80G resolution 1mm vs. 26G approximately 5mm.

Smaller blind spot: 80G blind spot 0.07-0.4m vs. 26G 0.8-1m.

Applicable scenario differences: 80G is suitable for fine measurement (such as small solid particles), while 26G is better suited for large and complex environments (such as large reservoirs).

5、 Selection suggestions

High precision requirements: Priority should be given to 80G, especially for low dielectric constant media or small containers.

Complex working conditions: choose anti-corrosion material models for high temperature and high pressure, and pay attention to beam angle optimization in dusty environments.

note

1: The measurement range starts from the point where the beam touches the bottom of the tank, but in special cases, if the tank bottom is concave or conical, measurement cannot be carried out when the level is below this point.

2: If the medium has a low dielectric constant, the bottom of the tank will be visible when it is at a low liquid level. To ensure measurement accuracy, it is recommended to set the zero point at a low height of C.

3: In theory, it is possible to measure the position of the antenna, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100mm away from the antenna.

4: For overflow protection, a safe distance can be defined to be added to the blind spot.

5: The minimum measurement range is related to the antenna.

Installation requirements for radar level gauge:

1. Recommended distance (1) from the wall to the outer wall where the short pipe is installed.

2. At a distance of 1/6 of the tank diameter from the tank wall, the minimum distance is 200mm.

3. It cannot be installed above the feeding port (4).

Attention: The measurement range starts from the point where the beam touches the lower part of the tank, but in special cases, if the tank is concave or conical, measurement cannot be carried out when the level is below this point. If the medium has a low dielectric constant and is visible at a low liquid level, it is recommended to set the zero point at a low height of C to ensure measurement accuracy. In theory, the measurement reaches the antennaThe location is possible, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at a distance from the antennaAt least 100mm. For overflow protection, a safety distance can be defined and attached to the blind spot. The minimum measurement range is related to the antenna.

Radar waves travel at the speed of light, and the travel time can be converted into level signals through electronic components. The probe emits high-frequency pulses and conducts them along cable and pole probes. When the pulses encounter the surface of the material, they are reflected back by the receiver inside the instrument, and the distance signal is converted into a level signal.
