Continuous Wave Radar Level Gauge Without Direct Contact With The Medium
Continuous wave radar level gauge is a common liquid level measurement instrument. It uses radar technology to emit continuous microwave signals and calculates the liquid level by measuring the intensity of the signal's echo.
| Characteristics | Continuous Wave Radar | Pulse Radar |
|---|---|---|
| Working Principle | Transmits waves with continuously varying frequencies and measures the frequency difference between the transmitted and received waves. | Transmits short pulses and measures the time difference between the transmitted and received waves. |
| Signal Processing | Processed in the frequency domain, requiring high signal quality and relatively complex circuits. | Processed in the time domain, with an intuitive principle and relatively simple circuits. |
| Accuracy | Extremely high. The accuracy of measuring the frequency difference can be very high, so it is usually more accurate than pulse radar. | High, but may be slightly inferior to FMCW in measuring extremely short distances or requiring extremely high accuracy. |
| Dead Zone | Minimal or almost non-existent. As it is a continuous wave, it can measure very short distances. | Has a certain dead zone (cannot measure near the antenna), as the receiver needs to be turned off during pulse transmission. |
| Cost | Usually higher (especially in high-frequency bands). | Usually lower, with good cost performance. |
| Application Focus | Applications with extremely high requirements for accuracy and reliability, such as trade settlement, fine chemicals, and small container measurements. | Strong versatility, suitable for most industrial liquid and material level measurements, and is one of the market mainstreams. |
Continuous wave radar level gauges, with their blind spot-free feature, ultra-high precision and outstanding reliability, are the "high-end" solution in industrial liquid level measurement. Although their cost is usually higher than that of pulse radar, they are the irreplaceable choice in demanding measurement points, small containers or situations requiring extremely high measurement stability, such as safety interlocks and trade handovers.
