The KSV BPA-800P bubble pressure tensiometer represents the latest development in bubble
pressure measuring technology. Many of the key features are patented such as the
determination of bubble lifetime characteristics, the optimization of the aerodynamic
system, and the option to reach extremely short as well as sufficiently long measuring times.
Automatic operation and user independence are the key features of the KSV BPA-800P. Portability
and battery operation make the instrument extremely useful in industrial and environmental
applications. User friendly external PC software makes data analysis and storage easy.

基本介绍

用于连续测量水位的精巧型气泡水位计。它具有高量程、高精度的特点,并带有4-20 mA模拟输出和SDI12标准接口,最新设计的智能型气泵可以在满足测量精度的前提下减小打气体积,以便节省系统功耗。

测量原理

仪器内部的活塞泵产生压缩空气,流经专用气流线,按设定好的间隔进入气室,在气室里,气泡均匀地冒出来进入水中。气泡室孔上水的液位(h)与测量管内流体静压(P)建立关系如下:P = ρgh那么,假设液体的密度保持不变,则测量液位和测量管内的空气压力之间就存在一定的线性关系。通过测量测管内的空气压力,就可以换算出当前的水位了。这就是气泡水位计测量液位的基本原理。

技术特点

简单的安装、设置和操作:无需任何设置或操作软件,用户可以直接通过仪器上的Dip开关进行现场设置防雷:在水下没有电子部件使用寿命高达5年:在最小每分钟测量一次的情况下具有5年的使用寿命集成接口:SDI 12接口,4-20 mA模拟输出可集成数据记录仪(CBL):内存扩充到4M;边界警报;与其他外部设备共同执行监测任务智能压缩泵,无需维护:自动调节功耗,保证精度压差测量原理,无零点漂移:即使在盐水或受污染的水体中,读数也准确而稳定可采用不同内径的安装管:φ 2 mm、φ 4 mm、φ 1/8”(USGS 标准)过压保护功能应用范围潮湿区、地下水、细长、平坦的斜坡(湿地)、堤坝/桥/水坝的入口和水闸等、岩基、有可能结冰或淤塞的验潮井、短期测量、干燥地区(水库,旱谷等等)。
