Yokogawa Portable Ultrasonic Flowmeter US300PM-A12-2-N/PU1
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 provide fast, accurate, and no-zero- offset flow measurements in clean to dirty fluids.
It can be used not only for the maintenance and the check of your facilities but also for the measurement at laboratories or manufacturing lines.
The measuring principle is based on the influence of the flowing fluid to the traveling time of sound. The sound is transmitted through the pipe and the transit time difference between the forward and backward directions is used to determine the flow velocity (transit time method).
Because of its clamp-on transducers, no cutting of the pipe is necessary and the measurement is independent of liquid pressure or conductivity.
FEATURES
Yokogawa Portable Ultrasonic Flowmeter US300PM-A12-2-N/PU1
• Quick and Easy Setup with Calibrated No-Zero- Offset Transducers
The transducers are matched-pair and factory-calibrated one by one, realizing no-zero-offset transducers with our latest electronics design, thus enabling quick and easy setup.
• High Accuracy Realized by our Exclusive Measuring Technology
The accuracy through process calibration is as high as 0.5% of reading realized by our patented digital signal processing for the correlation detection method.
• Stable Measurement against Air Bubbles
The measurement against air bubbles or entrained solids in the fluid has been improved greatly than was previously possible with our signal noise suppression technique.
• Dual-Channel / Dual-Path Inputs with Two Sets of Transducers for a Variety of Applications
The dual-channel enables two measurements in two separate pipes with one meter. The dual-path enables the measurement in a single pipe that reduces the effect of flow profile distortions. Addition / subtraction on two flow inputs are also available for specific systems.
• Dual Current Outputs as Optional
Maximum two current outputs are available as optional with free assignment of any flow value. When necessary, it is also possible to assign sound velocity and ultrasonic signal amplitude during the measurement.
• Wide and Simple Fluid Temperature Ranges for Transducers
The fluid temperature ranges for transducers are as wide and simple as –30° to 130°C / –30° to 200°C (–22° to 266°F / –22° to 392°F), enabling the measurement for wide temperature range heating/cooling systems.
• Data Logging Function for Site Trend Analysis
Data storage capacity of 27,000 values as standard and maximum 100,000 values as optional. Stored values can be transferred to a personal computer for analysis and storage via RS232 serial communication port.
• Built-in Wall Thickness Measurement Capability
With the built-in wall thickness measurement software in every meter, optional wall thickness probe enables you to measure the pipe wall thickness for proper setup of the transducers.
• Long Hour Battery Operation
Built-in battery for maximum around 10 hour continuous measurement is standard. The operation by AC power supply adaptor is provided as well.
