Analyze The Characteristics Of Radar Level Gauge And Differential Pressure Level Gauge

In industrial production, accurate measurement of various chemical liquids is a crucial part. Since some chemical liquids are volatile or toxic, manual measurement is no longer practical, so the application of professional instruments is particularly important. As one of the common instruments, liquid level gauge has derived many types under different working conditions and environmental requirements. Among them, radar level gauge and Differential pressure level gauge are the two main types of liquid level gauges.

The radar level gauge has strong adaptability and can adapt to different temperatures and media. The extremely narrow beam angle makes the radar energy more focused; it can be applied to long and narrow installation spaces without being interfered by false echoes; even if there are obstacles in the tank , such as stirring, heating coils, etc., extremely narrow beam angles can be successfully avoided to achieve accurate measurement; even if the measuring range is as high as 120m, the signal will not attenuate too much.

In contrast, Differential pressure level gauge was born earlier and is more suitable for industries with greater demand for traditional liquid level measurement. It has fast response and higher measurement accuracy, but has poor cold resistance. Insulation or heating measures are required in winter, and pipe leakage and condensation need to be monitored.

Generally speaking, although there are slight differences between radar level gauge and differential pressure level gauge, each has its own advantages. Radar level gauge measurement has high requirements on working conditions, environment and installation environment. It needs to be installed far away from the feed inlet to reduce the influence of signal reflection. It is more suitable for modern enterprises with high standard measurement requirements. The Differential pressure level gauge has a narrow adaptability range and can only be used under specific working conditions. The sensor is prone to zero drift, resulting in large measurement errors, low stability and accuracy, and is greatly affected by the surrounding environment, making maintenance and installation difficult. It is cumbersome and costly to use, and is more suitable for places that do not have high requirements for the measurement environment.
