多普勒超声流量计FDT50系列

对于水 排队 法兰

在线超声流量计•用于水服务的经济超声流量计•DN 32至200（2至8英寸）法兰•电池供电•显示流量和总数•延长的低流量范围•几乎没有压力损失•无运动部件长寿•NIST 3点校准包括•USB/RS232（可选）FDT500系列使用运输时间超声技术，其中信号在2个流动传感器之间交替传输并交替接收，并且“飞行时间”决定了流速。battery-powered transmitter comes in the user’s choice of an integrally mounted display or a remote-mount version. Applications include both commercial and consumable water measurement. Long-term stability and a wide measurement range make it possible not only to measure water consumption, but also to monitor systems for water leakage. Because the FDT500 Series has no moving parts, system pressure loss is minimal and filtration is not required. Display flow rate or total at the push of a button. Models are available with DN 32 to 200 or 2 to 8" 150-lb ANSI flanges.
