PULSAR流量计PDFM 5.1产品介绍
PDFM 5.1 是一款便携式多普勒流量计，只需夹在管道外部即可进行管道流量测量。其超声波多普勒技术使其非常适合用作水流量计，特别适用于含有气泡或固体的脏或难处理的液体，如废水、浆液、污泥、化学品、粘性液体和磨料。
PDFM 5.1 便携式多普勒流量计非常适合用于流量故障排除、平衡和检查永久性流量计的性能。快速且易于操作，传感器在不到一分钟的时间内安装到管道外部，使用内置键盘和校准菜单为应用设置流量计。
The PDFM 5.1 is a Portable Doppler Flow Meter that simply clamps to the outside of a pipe to gain pipe flow measurement. Its ultrasonic Doppler technology makes it perfect for use as a water flow meter, specifically for dirty or difficult liquids that contain bubbles or solids, like wastewater, slurries, sludge, chemicals, viscous liquids, and abrasives.
The PDFM 5.1 portable Doppler flow meter is ideal for flow troubleshooting, balancing, and checking the performance of permanent flow meters. Fast and easy to operate, the sensor mounts to the outside of a pipe in less than a minute, using the built-in keypad and calibration menu to set up the flow meter for the application.
