Large Measuring Range 80m 20G Radar Level Meter For Liquid Steam Dust Solid
Working principle
The radar object level antenna transmits microwave pulses from the window and transmits them down through the antenna. After touching the surface of the measured medium, the pulse wave is reflected back and received again by the antenna system, and the signal is transmitted to the electronic circuit and automatically converted into the object level signal < because of the extremely fast propagation speed of the pulse, the time it takes for the electromagnetic wave to reach the target and return to the receiver by reflection is almost instantaneous).
Datum of measurement: sealing surface of thread bottom or flange.
Note: When using radar level timing, it is necessary to ensure that the highest material level cannot enter the measurement blind area( the area shown in D in the figure).
Dsign feature
◎The antenna is too small, easy to install; Non-contact radar, no wear, no pollution.
◎It is almost not affected by corrosion, foam, medium density, temperature and pressure changes.
◎Serious dust environment has little effect on the work of high frequency level meter.
◎It has a shorter wavelength and better reflection against a tilted solid surface.
◎The beam Angle is small and the energy is concentrated, which enhances the echo ability and is conducive to avoiding interference objects.
◎Measurement blind area is smaller, for small cylinder measurement will also achieve good results.
◎High signal-to-noise ratio enables better performance even under fluctuating conditions.
◎High frequency, is the best choice for measuring solid and low dielectric constant media.
