# 2.2.3 安裝位置

夾管式超音波流量計的精度絕大部分比例決定於正確的探頭安裝，若安裝方法或位置錯誤可能導致無法達到預期的效果，甚至無法收發超音波訊號，一般最佳安裝位置的條件如下： 

● 把超音波探頭安裝在越長的管子上越好，並且確認管內充滿液體。 

● 將探頭安裝在管子的側面，可以減少氣泡，非滿管空腔等所造成的干擾。 

● 確保探頭能夠承受量測點的溫度。越接近室溫越好。 

● 在某些管內壁會有內襯雖然本產品可以經由設定來相容於具有內襯的管路，但實務上此一內層容易阻擋超音波之傳遞進而影響量測，如果可以的話安裝位置盡量避開這一類管子。

 **透過正確的探頭安裝將可大大提升您所需的量測精度。**
