Calculated data from sensor Q1 at Maisbich for month 2006-08

Height V-notch above sensor 0.145 m Parent item: Maisbich (Luxemburg), calculated data from discharge meter Q1, 2003-12 to 2008-05 Measuring instrument: Maisbich basin: V-notch discharge meter Q1 Type: Pressure Sensor Keller DCX-4.0, SN 1454 This instrument is based on differential pressure measurement of two absolute sensors. The sensors measure pressure and temperature. Height of V-notch above sensor: hV=0.145m. The discharge is calculated with the rating curve Q=C*(h-hV)^2.5 where C is a calibration constant and h results from the pressure difference (Willem Luxemburg, Martijn Westhoff).

传感器上方的V型缺口（V-notch）高度为0.145米。父数据集条目：卢森堡迈斯比奇（Maisbich）流域，所用数据为2003年12月至2008年5月期间由流量计量仪Q1计算得到的结果。测量仪器：迈斯比奇流域配套V型缺口流量计量仪Q1。仪器型号：凯勒（Keller）DCX-4.0型压力传感器，序列号SN 1454。该仪器基于两台绝对式传感器的差压测量原理，可同时采集压力与温度数据。传感器上方V型缺口高度：h_V=0.145米。流量通过率定曲线Q=C*(h-h_V)^2.5计算得到，其中C为校准常数，h由压差推导得出（数据来源：Willem Luxemburg、Martijn Westhoff）。贡献者：Durr, E.H.（Eugene）
