Guided wave radar and non-contact radar are two mainstream radar level measurement technologies widely used in industrial process monitoring. Although both work based on microwave electromagnetic wave reflection theory, they differ fundamentally in structural design, working mechanisms, and medium applicability. Guided wave radar adopts contact probe transmission, while non-contact radar realizes non-invasive measurement through air-propagating microwaves.

As two mainstream types of radar level measuring equipment, pulse radar and Frequency Modulated Continuous Wave (FMCW) radar level meters are widely used in industrial liquid and solid level monitoring. Both devices rely on the reflection principle of high-frequency microwaves, but they adopt completely different signal transmission and data processing mechanisms, leading to significant differences in measurement accuracy, anti-interference performance and applicable working conditions.

Radar level meters are widely adopted industrial measuring instruments for liquid and solid level monitoring, featuring high precision, strong stability, and excellent adaptability to harsh working conditions. Different from traditional mechanical and ultrasonic level measuring devices, radar level meters work based on the propagation and reflection law of high-frequency electromagnetic waves.

Traditional impeller flowmeters have been widely used in industrial fluid measurement for decades due to their simple structure, reliable mechanical performance and low manufacturing cost. As typical mechanical velocity-type measuring instruments, they can basically meet the basic flow metering demands of conventional industrial scenarios. However, with the rapid development of industrial digitization, smart factories and automated process control systems, traditional mechanical flowmeters expose prominent limitations.

Impeller flowmeters are widely adopted in industrial fluid measurement due to their high linearity, low cost and stable dynamic response. Their measurement principle relies on the linear proportional relationship between fluid flow velocity and impeller rotational speed under rated working conditions.

The chemical industry is characterized by complex production environments, where flammable, explosive, volatile and corrosive media are commonly transported and processed. Fluid flow measurement is an indispensable part of chemical process control, and the operational safety of measuring instruments directly determines the stability of factory production.

With the continuous upgrading of industrial intelligent measurement systems, intelligent impeller flowmeters have replaced traditional mechanical flowmeters and become key equipment for fluid flow monitoring in petrochemical, water supply, pharmaceutical and energy industries.

Industrial impeller flowmeters are pivotal velocity-type measuring instruments widely used in petrochemical, water treatment, energy transportation and other industrial fields. In complex industrial operating environments, equipment often faces various interferences, including pipeline mechanical vibration, fluid turbulence, electromagnetic signal interference and ambient temperature fluctuation.

Liquid medium measurement is a core part of industrial production, municipal engineering, and commercial metering. Accurate and real-time flow detection of liquids such as clean water, industrial solvents, and light oil directly affects production efficiency, material accounting, and energy consumption control.
