应用实例:水电站出口流量监控

航道流量、洪水防御和环境保护监控:这些工作是平时不感觉重要,非常时期就可以发挥巨大作用,而这种工作都取决于长期有效和高精度流量测量。就现在许多用户,在这些情况选择一个液位计测量高度(液位),来监视大的明渠或者河流的水位,不是监视流速,只测量水位的变化,不关注流速的变化,这只是一个临时的方法和没有保障的办法。因为有洪水发生的时候,是先出现河道流速加快,流量加大,水位变化不大,特别的宽的河道,所以有效的测量是需要监控河道的平均流速和流量,同时结合液位计测量水位的变化。

现在,德尔塔波可以提供一个连续和高精度的流量测量,这算法和产品是经过反复考验的时差法产品--多声道内贴式超声波流量计(deltawave),可以确保提供可靠的流量数据:可以是免维护和高精度。

 


连续测量:免维护和高可靠性

systec fluss

The river Eder is piled up in order to feed a hydro power plant. The plant operator is obliged by public decree to ensure a minimum outflow of 6 m3/s for environmental and touristic purposes. The competent water management council formerly used a temporary ultrasonic flowmeter (ADCP) to monitor the flowrate. The ADCP offers a relatively precise but only a temporary measurement and always needs cost-intensive staff employment

By contrast, deltawave provides a continuous, automated and very accurate flow measurement.


Simple Mounting - withstand harsh conditions

The measurement site was equipped with a 4-path system. The ultrasonic transducers are mounted on a H-beams using a mounting clamp made of stainless steel which also protects the transducers against floatsam. Your advantage: The measurement works maintenance-free and calibration-free based on international standards (ISO6416). The flowdata can be transferred to the control room via a standardised 4..20mA-signal or a GSM-Modem.


Measurement parameters

  • Flume type: River, Width=30m
  • Medium: River water
  • Number of Paths: 4
  • Type of transducer: 250 kHz
  • Mounting of the transducers: On H-beams
  • levelmeter: ultrasonic
  • Path lengths: 40m
  • Typical flow speed. 1 m/s
