本文介绍了一种分析仪器——动态分析仪的研制 探头，用于监测和分析水或废水过滤床。这 分析仪器能够在各种条件下测量可用压头 运行中滤床的位置，以及不同压力下的压力 逆流（反洗）期间穿过滤床的位置。此外， 该分析仪能够与监控和数据采集进行通信 （SCADA）计算机和/或可编程逻辑控制器（PLC）， 可寻址通信协议。

This paper describes the development of an analytical instrument, the Dynamic Probe, designed to monitor and profile a water or wastewater filter bed. This analytical instrument is capable of measuring the available head at various locations across the filter bed in service and also the pressure at various locations across the filter bed during reverse flow (backwash). Additionally, this analyzer is able to communicate to Supervisory Control and Data Acquisition (SCADA) computers and/or Programmable Logic Controllers (PLC) through an open, addressable communications protocol.
