The operation mode of the radar level gauge is introduced

Radar liquid level gauge with pulse wave and frequency modulation continuous wave two main working mode.

pulse wave ( 脉冲) Way: most pulsed radar level gauge used for 58 GHZ microwave frequency, radiation Angle is bigger, about 02 ~ 03% FS precision, microwave under general intermediate level meter in this way.

frequency modulation continuous wave ( FMCW) Method: measuring circuit is complex, high accuracy can reach 01% FS, clutter echo also relatively easy to remove.

the advantages of radar level gauge include by microwave is electromagnetic wave, traveling at the speed of light and is not affected by dielectric properties, in some situations, such as temperature, pressure, steam, ultrasonic level meter cannot work normally, and radar level meter can be used; Most of the material level meter for two-wire system integration products, save a lot of cables; Software debugging is convenient.

the shortcoming of radar level gauge includes: the price is higher, the two wire radar level gauge 24 VDC power supply quality is higher, ac harmonic average no more than plus or minus 30 vac. Radar level gauge internal power supply module are susceptible to other large current interference and damage, reason should be the power to dismantle the indicator; Measurement of solid materials, easy to produce interference echo, reduce the measuring result, so does not apply to a measure of the solid materials.
