The HWLB10 radar level meter antenna emits an extremely narrow electromagnetic microwave pulse, which travels in the air at the speed of light, encounters the surface of the measured medium, and some of its energy is reflected back and received by the same antenna. The time interval between transmitting and receiving pulses is proportional to the distance of the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves, the time interval between the transmitted pulse and the received pulse is very small (on the order of nanoseconds). The radar level meter uses a special correlation demodulation technique, which can accurately identify the time interval between the transmitted pulse and the received pulse, so as to further calculate the distance from the antenna to the surface of the measured medium. ● Energy concentration, anti-interference ability, improve the measurement accuracy and reliability; ● Cable (rod) antenna, contact with the medium measurement, good guidance, no loss of signal, can achieve accurate measurement under low frequency conditions; ● Not affected by dust, steam and medium adhesion, not limited by the characteristics of the medium; ● The foam on the liquid surface has no effect on the measurement; ● Output signal 4-20mA with HART communication protocol ● Suitable for the occasion of weak echo or large interference, mainly used in the measurement of liquid solid medium, such as metallurgy, petroleum and petrochemical, coal, chemical industry storage tank or process complex container measurement
