Fuji Electric's FSV ultrasonic flowmeter is the latest generation of high-performance ultrasonic liquid flowmeters using transit time technology. It is particularly effective in applications where high accuracy is required and the flowmeter needs to be installed without stopping the process. It's the perfect option for measuring the flow of relatively clean, homogeneous liquids in closed, filled pipes.

How does the FSV ultrasonic liquid flowmeter work?
Ultrasonic flow meter measures flow by operating on the transit time principle technology.
This clamp-on ultrasonic flow meter works by comparing the travel time of an ultrasonic signal in the direction of flow (downstream) and the counterflow sound wave (upstream).
These high-frequency ultrasound signals are generated by two clamp-on transducers through the pipe wall.
The difference between these two transit times is proportional to
the flow rate. The ultrasonic flow meter converts these measuring data into a flow measurement.
How does the Time DELTA-C ultrasonic liquid flow meter work?
The FSV ultrasonic flow meter uses clamp-on transducers for measuring flow rates.
These sensors attach to the outside of pipes and can be used on wide pipe sizes from 13 to 6000 mm (0.5 to 235 inches) at liquid temperatures from -40 to 200°C (-40 to 390°F).
The required pipe system layout is a straight run of 10x and 5x pipe diameters upstream and downstream respectively.
The clamp on ultrasonic transducers are mounted outside the pipe, which is a superior method compared to insertion flow meters and other more traditional invasive flow measurement instruments.
This transit time ultrasonic technology offers minimal maintenance and significantly reduced the installation time.
What are the advantages of the Time DELTA-C ultrasonic flow meter ?
Advanced digital signal processing and anti-bubble technology
Advanced electronic signal processing technology allows the FSV ultrasonic flow meter to offer a compact, lightweight solution for flow measurement with high accuracy better than ±1 % of flow, and with minimal influence of pressure or temperature of the measured fluid.
In addition, it offers best-in-class anti-bubble performance, allowing accurate readings even on process when air bubble content reaches 12 % of volume at a velocity of 0.3 m/s.
Wide range of flow measurement signal outputs
The transit time clamp-on ultrasonic flow meter has three signal outputs that can be selected to display flow measurements (volumic flow or mass flow) and total flow.
Various output options, such as 4-20 mA signal output, transistors pulse output and digital communication are available.
Configurable alarm thresholds can be set to detect overshoot in flow measurement, switch on a relay and allow rapid action to be taken for the safety of your process.
Simple and intuitive operator interface
The FSV ultrasonic flow meter is a compact meter with a large choice of reading displays.
Configuration is simple and intuitive using push buttons on the front panel.
The ultrasonic flow meter electronic converter calculates the sensor spacing and guides you for the commissioning.
It can be configured to automatically calibrate the zero of the flow meter.
An LCD display and an integrated keypad allow the user to configure the unit simply and easily and to view the range of parameters.
The internal menus are available in several languages (French, English, German, Spanish and Japanese).
PC configuration software
The ultrasonic flow meter can also be configured using PC-compatible free software and a communication cable allowing multiple configurations to be stored and downloaded to flowmeter from a PC.
What are the applications of the ultrasonic flow meter FSV ?
The ultrasonic flow meter Time Delta-C model FSV consists of a sensor that can be installed on the conduct (DN 13 to 6000 mm depending on the sensor) and a remotely mounted digital converter.
The flow velocity can be bidirectional and vary from -32 to +32 m/s. FSV utrasonic flow meter is well suited to relatively clean fluids with low to moderate aeration.
