US300FM Ultrasonic Flowmeter

Yokogawa US300FM Ultrasonic Flowmeter

Yokogawa US300FM is an ultrasonic flowmeter for measuring liquid flow in a fully filled pipe. With the advanced signal processing and correlation detection method, US300FM provide fast, accurate, and no-zero- offset flow measurements in clean to dirty fluids.
 

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

• 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 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 reducing the cost per measurement point. 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

Maximum two current outputs are available 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.
 

• Small Sizes and Light Weights Making the Installation Work Simple and Easy

The main unit has only about 7 cm (2.8 inches) depth and 2.8 kg (6.17 lb) weight, enabling simple wall- mounting installation. The transducers (sensor elements) are also as small as we can hold them in our hand, enabling the installation even at limited places quick and easy.
