Like light waves of much higher frequency, radar waves tend to travel in straight lines or rays at speeds approximating that of light. In most radar systems, the received targets are amplified, converted into video frequency signals, and then presented to the operator on various types of CRT (cathode ray tube) displays. - Low cost, accurate, reliable and robust device for long term installations. After the radar signal is reflected by the liquid surface the echo is picked up by the antenna. The radio uses a transmitter to produce an electromagnetic signal that is then propagated into the space using an antenna. Frequency modulated continuous wave.

Therefore, the Radar cannot receive the signal during . Radar level transmitters work based on the time of flight (TOF) measuring principle or time domain reflectometry (TDR). Since the frequency of the frequency band is relatively low, the bandwidth is relatively narrow (only 250 MHz), so the 24 GHz millimeter wave radar is limited in measurement accuracy, which also limits its application range. To start with, we can measure the distance from the reference point to the surface of a liquid. As one of radar level transmitter manufacturers, we are devoted to provide high-quality products and services. The measurement technology of this type of radar level transmitter is usually used to measure, and it is not affected by vacuum, dust, temperature, pressure changes, steam and falling gases.

A continuous-wave radar uses Doppler technology which means the radar will be immune to any form of interference by large objects that are stationary or slow-moving. electromagnetic waves usually in the microwave X-band range which is near about 10 GHz.Hence, they can be also known as microwave level measurement devices. As shown in the figure, Radar mainly consists of a transmitter and a receiver. Not affected by pressure, vacuum or temperature. First introduced in the form of a backup camera by Toyota in 1991, camera is the oldest type of sensor used in vehicles. They can be used in simple as well as in aggressive liquids and are suitable for applications with stringent hygiene requirements. These transmitters are normally mounted at the top of a tank filled with a liquid. The radar transmitters have many types of antennas and this could be selected according to the application While measuring vapor and foam we can use low frequency The high frequency is used for other applications rather than vapor and steam If the radar transmitter is mounted in the vessel then we should use isolation valves with it Non-Contacting Radar sends down an electromagnetic wave The radar sensing is a wireless sensing technology that extracts and discovers the target's position, shape, motion characteristics and motion trajectory by analyzing the received target echo characteristics.
