品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……进口液体超声波流量计产品用途 Product use
超声波在管道中的传播时间受管道中的流速的影响，逆流传播时间比顺流传播时间要长，且传播时间差与流速成正比。可测介质包括水、废水、油类等均匀稳定液体，应用领域包括给水排水、石油化工、供暖发电、造纸冶金、食品医药等诸多行业，能满足大部分工业现场对液体流量的准确测量与监控的需求retz The propagation time of ultrasonic waves in the pipeline is influenced by the flow velocity in the pipeline. The propagation time in the upstream direction is longer than that in the downstream direction, and the propagation time difference is proportional to the flow velocity. The measurable media include uniformly stable liquids such as water, wastewater, and oils, and their application fields include water supply and drainage, petrochemical industry, heating and power generation, papermaking and metallurgy, and food and pharmaceutical industries. They can meet the needs of most industrial sites for accurate measurement and monitoring of liquid flow
