一、 Product Information
The model US300PM is a portable ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300PM provides fast, accurate, and no-zero offset flow measurements in clean to dirty fluids.
二、 Features
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)
