原理
雷達(dá)物位計天線發(fā)射較窄的微波脈沖，這個脈沖以光速在空間傳播，遇到被測介質(zhì)表面，其部分能量被反射回來，被同一天線接收。發(fā)射脈沖與接收脈沖的時間間隔與天線到被測介質(zhì)表面的距離成正比，從而計算出天線到被測介質(zhì)表面的距離。
特點(diǎn)
由于采用了的微處理器和獨(dú)特的EchoDiscovery回波處理技術(shù)，雷達(dá)物位計可以應(yīng)用于各種復(fù)雜工況。
“虛假回波學(xué)習(xí)”功能使得儀表在多個虛假回波的工況下，可正確地確認(rèn)真實回波，獲得準(zhǔn)確的測量結(jié)果。
多種過程連接方式及天線型式，使得WTCRD5X系列雷達(dá)物位計適于各種復(fù)雜工況及應(yīng)用場合。如：高溫、高壓及小介電常數(shù)介質(zhì)的測量等。
采用脈沖工作方式，雷達(dá)物位計發(fā)射功率極低，可安裝于各種金屬、非金屬容器內(nèi)，對人體及環(huán)境均無傷害。

Principle: the radar level gauge antenna transmits a narrow microwave pulse, which propagates in space at the speed of light.

When it encounters the surface of the measured medium, some of its energy is reflected back and received by the same antenna.

The time interval between the transmitting pulse and the receiving pulse is proportional to the distance from the antenna to the

measured dielectric surface, thus the distance from the antenna to the measured dielectric surface is calculated.

Features: because of the advanced microprocessor and unique EchoDiscovery echo processing technology, radar level meter

can be used in all kinds of complex working conditions. The "false echo learning" function enables the instrument to

correctly confirm the true echo and obtain the accurate measurement results under the condition of multiple false echoes.

A variety of process connection modes and antenna types make WTCRD5X series radar level meters suitable for

various complex working conditions and applications. Such as: high temperature, high pressure and small dielectric constant measurement, etc.

The radar level meter can be installed in all kinds of metal and non-metal containers without harm to human body

ａnd environment by means of pulse working mode, the radar level meter emits very low power and can be installed in various

metal and non-metallic containers. Characteristic: trumpet antenna, small beam angle. Should be used: liquid measurement or short-range solid measurement.

Able to adapt to complex process conditions. Maximum measuring range:
