Guided wave radar level gauge can measure the interfaces of two different media, make full use of the dielectric constant of the media, the product can emit high-frequency microwaves, spread along the probe, due to the encountered medium, the dielectric constant changes Causes reflections. The time interval between the transmitted and reflected pulses is proportional to the distance to the medium being measured. At the same time, guided wave radar also. However, the measurement condition is that the upper layer dielectric is not conductive, or its dielectric constant is less than 10 times the dielectric constant of the lower layer dielectric. The working mode of the pulse can measure the medium with small dielectric constant, and it is safe to apply in various metal and non-metal containers, and it has no harm to the human body and the environment. Product applications and coal plants, power plants, petrochemicals, food industry and general industrial applications.
Guided wave radar level gauge according to the different media can be divided into: rod type and cable type two, what is the difference between the two? details as follows:
1. In terms of measuring range (cans), rod type is not suitable for too large range, because the rod type is too long to be easy to transport and install. Small range of choice rod type. If there is foaming (foaming), boiling surface or turbulence (fluid fluctuation) in the process media, rod antenna is recommended; cable antenna flexibility can also be, but the effect is not rigid.
2, cable type is not limited by the length, measuring a large range of optional cable type. The process medium is a viscous liquid or a solid powder. A flexible antenna is recommended. The rod type can also be used, but the effect is not flexible.
Above, we are just a brief introduction to the rod type and cable type of the guided wave radar level gauge. If you have any questions, please call our technical personnel and we will give you a serious answer to ensure that you finally choose the right product.
