液(ye)位計廠家告訴您超聲波液(ye)位計怎么調(diao)試？

超聲波液(ye)位(wei)計(ji)調試安裝時，換(huan)(huan)(huan)能器發(fa)射(she)面(mian)(mian)(mian)到(dao)低(di)液(ye)位(wei)之間的距(ju)離應小(xiao)于超聲波液(ye)位(wei)計(ji)的量(liang)程，換(huan)(huan)(huan)能器發(fa)射(she)面(mian)(mian)(mian)到(dao)高液(ye)位(wei)之間的距(ju)離應大于液(ye)位(wei)計(ji)盲區，換(huan)(huan)(huan)能器發(fa)射(she)面(mian)(mian)(mian)應該與被(bei)(bei)測液(ye)面(mian)(mian)(mian)保持平行，這樣聲波就可以(yi)垂(chui)直發(fa)射(she)到(dao)被(bei)(bei)測液(ye)面(mian)(mian)(mian)，以(yi)保證(zheng)能量(liang)返回。

分體式超(chao)聲(sheng)波液位(wei)計(ji)是一種(zhong)智能型非接觸式物(wu)位(wei)測(ce)量(liang)(liang)(liang)儀表。產(chan)品具有(you)(you)自(zi)動功(gong)率調整，增益(yi)控制，溫度(du)補償，采用(yong)好的檢測(ce)技術和計(ji)算技術，提(ti)高(gao)儀表的測(ce)量(liang)(liang)(liang)精度(du)，對干擾回波有(you)(you)抑制功(gong)能，保證測(ce)量(liang)(liang)(liang)結果的真實。產(chan)品用(yong)于液體的液位(wei)和固(gu)體的物(wu)料高(gao)度(du)的測(ce)量(liang)(liang)(liang)，也(ye)可用(yong)于距離的測(ce)量(liang)(liang)(liang)。
