液體、物位的測量：對于液面相對平穩(wěn)的罐體，且被測液體的介電常數(shù)較高，可以選擇普通雷達(dá)物位計(jì)。對于液面波動大、或帶有攪拌的罐體，或被測液體的介電常數(shù)較低，應(yīng)推薦導(dǎo)波雷達(dá)。因?yàn)閷?dǎo)波管對液面有整型作用，且導(dǎo)波雷達(dá)的微波反射不易受環(huán)境條件變化的影響。被測液體的介電常數(shù)和密度變化對測量結(jié)果沒有影響。對于被測液體的粘度≥500cst，且液體粘附性較強(qiáng)的情況，不能選擇導(dǎo)波管方式測量，因?yàn)檎掣胶徒Y(jié)晶會堵死導(dǎo)波管。從而形成虛假物位?？梢赃x擇導(dǎo)波桿方式來測量。當(dāng)介質(zhì)在探頭上的涂污對測量物位的影響可分為兩種：膜狀涂污和橋接。膜狀涂污是在物位降低時(shí)，高粘液體或輕油漿在探頭上形成的一種覆蓋層。由于這種涂污在探頭上涂層均勻，因此對測量基本無影響；但橋接性涂污的形成卻能導(dǎo)致明顯的測量誤差，當(dāng)塊狀或條狀介質(zhì)污垢粘結(jié)于波導(dǎo)體上或橋接于兩個(gè)波導(dǎo)體之間時(shí)，就會在該點(diǎn)測得虛假物位。連續(xù)調(diào)頻技術(shù)測量物位是將傳播時(shí)間轉(zhuǎn)換成頻差的方式，通過測量頻率來代替直接測量時(shí)差，來計(jì)算目標(biāo)距離。</p><div
