26G Radar Level Transmitter with High Frequency for Fast and Accurate Measurements
26G Radar Level Meter Working Principle
The radar horizontal antenna emits a narrow microwave pulse that is transmitted down through the antenna. The pulse is reflected back to the antenna system upon contact with the surface of the environment to be measured, and the signal is automatically converted to a level signal for transmission to the electronics department (due to the extremely fast propagation of the pulse, the time for the electromagnetic wave to reach the target and return to the receiver via reflection is almost instantaneous).

26G Radar Level Meter Design Features
Small antenna size, easy to install; Non contact radar, no wear, no pollution.
Almost free from corrosion and foam; It is not affected by the change of medium density, temperature and pressure.
Severe dust environment has little impact on the operation of high-frequency level meter.
Shorter wavelength, better reflection for inclined solid surfaces.
The beam angle is small and the energy is concentrated, which not only enhances the echo ability, but also helps to avoid interference.
The measurement blind area is smaller, and good results will be achieved for small tank measurement.
High signal-to-noise ratio, even in the case of fluctuations can also obtain better performance.
High frequency is the best choice for measuring solid and low dielectric constant medium.
