Shandong Radar Level Meter Manufacturer: What are the Differences Between Different Radar Level Meters

2021-09-15


Radar level gauges can be divided into contact radar level gauges and non-contact radar level gauges according to their working methods, as follows:

1. Non-contact radar level meter

The non-contact radar level meter uses a horn or a rod antenna to transmit and receive microwaves. The instrument is installed on the top of the silo and does not contact the measured medium. The microwave propagates and returns in the upper space of the silo.

Non-contact radar level meters can be divided into pulse radar level meters and FM continuous wave radar level meters according to the waveform of microwave.

2. Contact radar level meter

Contact radar level meters generally use metal wave conductors (rods or steel cables) to conduct microwaves. The instrument is installed from the top of the warehouse, and the guided waves reach the bottom of the warehouse. The emitted microwaves propagate downward along the outside of the wave conductor, and are absorbed when they reach the material surface. Reflected, along the waveguide back to the transmitter to be received.

This kind of contact radar level gauge, which can be measured by directly contacting the material to be measured through a waveguide or a probe, is mainly a guided wave radar level gauge. According to the metal waveguide used, it can be further subdivided into : Cable type (single/dual), rod type (single/dual) and coaxial guided wave radar level meter.

Compared with the contact radar level gauge, the non-contact radar level gauge has the advantages of simple installation, less maintenance, flexible use, and is not affected by factors such as dust and temperature in the warehouse. It is a kind of rapid development in recent years. measuring instrument.

Application difference

The application range of radar level gauge is very wide, covering electric power, steel, metallurgy, cement, petrochemical, papermaking, food and other fields, but the application conditions of radar level gauges with different principles are also different.

Pulse radar level gauges can generally be used in most applications, mainly for liquid level measurement of cylindrical and tank media within 35 meters; but for spherical tanks or liquid storage tanks with stirring function, guided wave radar is required. For the container or storage tank with large range and large dust, it is necessary to use the FM continuous wave radar level gauge with high energy and strong anti-interference ability.
