US300PM Portable Ultrasonic Flowmeter

More accurate measurements under difficult conditions
- New noise suppression technique improves accuracy of measurements with fluids where air bubbles are present
Fast response
- Yokogawa signal processing technology improves the speed and accuracy of measurements
Easy installation and adjustment of transducers
- Transducers are small and light enough to hold in one hand
- Each sensor calibrated before shipment, eliminating need to tune on-site
- No longer necessary to adjust the zero flow condition
Easy setup with interactive parameter setting process
Two flow-input channels are provided as a standard feature
A maximum of two current outputs enable the simultaneous measurement of flow and sound velocity
A wall thickness measurement function is provided as a standard feature (wall thickness probes are sold separately)
Data logging provided as a standard feature (maximum of 100,000 values)
Data transfer function via RS232 port
Extended battery life (maximum 14 hours)
