WUDF 71 Ultrasonic Doppler Clamp-on Ultrasonic Flow Meter is designed for measuring liquid with suspended solids, air bubbles or sludge in a sealed closed pipeline. Non-invasive transducers are mount-ed outside surface of the pipe. It has advantage that measurement is not inﬂuenced by pipe scale or blockage. Simple installation and easy calibration as unnecessary pipe cutting or ﬂow stop.

Features

Non-invasive Installation, Unnecessary pipe cuting or ﬂow interruption
Measuring Accuracy ±0.5% ~ ±2%F.S
Signal Automatic Gain Adjustment
Anti-interference Frequency Converter
Simple Operation, Only Input Inner Diameter To Realize Flow Measurement
2*8 LCD Display Flow Rate, Volume, Velocity, etc

Applications

Raw sewage
Return activated sludge Waste activated sludge Ground water
Pulp and paper slurry Chemical slurry Drainage
Mining recirculation
