guided wave radar level meter is a microwave level meter, it is microwave ( Radar) A use of positioning technology. It is through a wave can be used to launch energy ( For general pulse signal) Device emitting energy of wave energy in the waveguide transmission, energy wave encounter obstacles reflections, the energy of the reflection wave from waveguide transmission to receivers, again by the receiving device to receive reflected signal. According to the measured energy wave motion in process of time to determine the level changes. By an electronic device of the microwave signal processing, eventually into the electrical signals associated with material level. Radiation energy level is low, the equipment using the energy wave is wave pulse energy ( Frequency is generally lower than the intelligent radar level meter) 。 The maximum pulse energy wave pulse energy is about 1 mw ( Average power is 1 & mu; W) , no radiation damage to other equipment and personnel.

1, the high frequency radar level gauge means has high energy, beam Angle is small, the antenna size is small, the advantages of high precision.

2, radar wave reflection mainly comes from the diffuse reflection, diffuse reflection intensity is proportional to the size of the material, and is inversely proportional to the wavelength, and most of the bulk material directly by the far less than 50 mm, this is why the current 26 GHZ radar is the best choice of bulk material level measurement.

3, in some small diameter, high short canister applications, a jar of medium or strong corrosive medium volatile gas, measured with ultrasonic effect is poor, radar effect is good, 26 GHZ radar frequency high frequency, short antenna, directional well, overcomes the drawback of 6 GHZ radar, applicable to small tank measurement.

4, due to the site conditions, as time goes by radar antenna will accumulate dirt, moisture, etc. , plus the radome can greatly improve the dirt, moisture influence. More consulting web:
