           LDM-51 智能化明渠流量測量系統——閘控一體化、全渠寬流量計是唯一款能直接測量過流斷面平均流速的智能型明渠流量計。該系統與目前其他流量儀表測量方法相比,該系統是直接得到面平均流速的,后者得到的是線平均流速或者點平均流速。綜合比較起來,該系統的測量精確度較高。

    該系統提供不同環境下流量測量的完美解決方案,可以運行在一些惡劣環境下,包括規則和不規則渠道開放式、封閉式的斷面流量、流速的測量。

     

      全渠寬流量計可以測量液位、平均流速和累積流量;

     可以精準測量不同形式的斷面流速;

    測量不受水中漂浮物、泥沙含量、水位變化、溫度的影響;

    流速傳感器安裝方便、對水流不產生阻力。標準斷面不需要改造即可直接安裝,安裝施工難度小、費用低;

    儀表顯示功能:可同時顯示水位、斷面平均流速、斷面瞬時流量、累計流量等;

    配套閘門使用可實現精準的測控一體化,可測量閘前及閘后水位、閘門開啟度等;

    具有數據永久保存功能,可在長期斷電的情況下保存設置參數和流量值;

    儀表具有標準的modbus(RTU)輸出的485接口、雙路模擬量輸入接口配套使用;

    使用注意事項

    1、安裝位置要盡量選擇在渠道或河道比較平直的地段,選擇儀表規格接近渠道寬度。

    2、智能化明渠流量測量系統的所有連接線要盡量短,盡量避開動力線,做好連接線的防水、防潮、防斷、屏蔽處理,保證接線的正確無誤。

    3、配合閘控安裝選擇匹配口徑的流量儀表。
