详细内容

产品名称:水质流速测量仪 水质流速分析仪 便携式流速超声波测量仪
产品型号:BX608-ISCO 4250
简介
·标准和低断面面积流速传感器
ISCO4250速度面积便携式流速超声波测量仪探头的流线型造型避免了有机物残渣和水流中化学成分的腐蚀
·密封设计能避免油脂堵塞,从而使其长期可靠运行
·标准探头适用于较大管径,带有高浓度悬浮固体和气泡的混浊水流
·低断面探头适用于浅流,水位可低至1英寸(25毫米)·可选择电话调制器-提供获取远程数据,语音信息,和警报信号
·可以支持不超过3个单独的内部4-20mA输出
·美国ISCO4250速度面积便携式流速超声波测量仪即便在槽或堰不适用、探头被浸没、满管、过载或有逆流发生的地方
·4250均可为您提供较高的测量精度,现场显示和打印
特点
·打印显示一体式结构
·带有微处理器的数字探头确保读数稳定(防止液位偏差)
·无需量程校准现场一点校准
·没有温度漂移
·自动修正泥沙液位
·对各种不同的液体自动增益控制
·传感器不受液位降低影响
应用场合
·容量评价
·入流和渗流研究
·下水道溢流研究
·生活污水评估
·明渠流量测量
