Comparison of high-frequency radar level gauge and ultrasonic level gauge
high-frequency radar level gauge | ultrasonic level gauge | |
range | Measuring range includes dead zone | No dead zone |
temperature | The ambient temperature requirement is -30 ~ 65 ℃. If it is lower than -30 ℃, heat tracing is required. Process temperature range Solid standard type: -40 ~ 130 ℃ High temperature type: -40 ~ 240 ℃ | Display instrument -20 ~ + 60 ℃, Probe -20 ~ + 80 ℃ |
application | Measurement of powder, granules, blocks and other solids; hydraulic and liquid conditions | Water environment and pure solid environment |
output signal | RS485 output signal with single selection | Optional 485 or 232 communication |
protection class | IP67 | Display instrument IP65, probe IP68 |
power supply | 12-24VDC/220VAC | Standard 24VDC Optional 220V AC + 15% 50Hz Optional 12VDC or battery powered |
advantage | Can be used in more complicated working environment, can be used in measurement environments such as strong corrosiveness, strong steam, acid gas, etc; easy to crystallize environment | Product is cheap and easy to install and use |
Disadvantage | Price is more expensive than ultrasonic level gauge | 1. The reflecting surface should be as flat as possible 2. If there is a trace of foam on the reflective surface, the range of the meter should be increased. 3. On-site non-closed environment, the range of the instrument needs to be increased when there is a small amount of steam 4. There is sound attenuation, can not be used in complex working conditions |
measurement accuracy | ±1 mm | 0.5%-1.0% |
The sound wave is a mechanical wave with a density of 40; gas, liquid and solid 41; propagation depends on the influence of the medium, temperature and pressure on the measurement. Need temperature compensation. Temperature and pressure measurement are generally not applicable. First of all, the ultrasonic level gauge has a temperature limit. Generally speaking, the temperature of the probe cannot exceed 80 degrees, and the propagation speed of sound waves is greatly affected by temperature. Secondly, the ultrasonic level gauge is greatly affected by the pressure, generally within 0.3MPa, because the ultrasonic wave is emitted by the vibration of the piezoelectric material. When the pressure is too high, the sound part will be affected. Third, when the fog or dust in the measurement environment is large, the measurement effect is not good. The radar level gauge emits high-frequency pulses and propagates along the cable. When the pulse is in contact with the material surface, it is reflected by the receiver inside the instrument and the distance signal is converted into a material level signal. The electromagnetic wave is used as the detection signal, which is reflected to the interface as the dielectric constant changes. Electromagnetic waves can propagate in vacuum without being affected by changes in temperature and pressure. Therefore, it can be used in a high temperature and high pressure environment. The measurement of very low dielectric constant media is not applicable. The radar tube uses electromagnetic waves and is not affected by the degree of vacuum. It has a wide range of applications in terms of medium temperature and pressure. The emergence of high-frequency radar tubes makes the application range of radar tubes wider. Therefore, the radar tube is an
ideal choice for level measurement.
