Summary
PUDF305 Doppler portable ultrasonic flow meter is designed for measuring liquid with suspended solids, air bubbles or sludge in a sealed closed pipeline. Non-invasive transducers are mounted outside surface of the pipe. It has advantage that measurement is not influenced by pipe scale or blockage. It’s simple to install and calibrate due to unnecessary pipe cutting or flow stop.
Features
l Chargeable Lithium Battery Can Continuously Work For 50 Hours
l Non-invasive Installation, Unnecessary pipe cutting or flow interruption, Acceptable Media Temperature Up To 260℃
l Measuring Accuracy ±0.5% to ±2.0%F.S
l Signal Automatic Gain Adjustment
l Anti-interference to Frequency Converter
l Simple Operation, Only Set Inner Diameter To Realize Flow Measurement
l 2*8 LCD Display Flow Rate, Volume, Velocity etc.
