The non-intrusive ultrasonic flowmeter for liquids optimizes your industrial processes and saves energy. Ultrasonic flow measurement technology reduces costs and improves plant safety. Thanks to its precise flow measurement capability, this device offers a reliable solution for real-time monitoring and process optimization.
The benefits of a non-intrusive ultrasonic flowmeter
Fuji Electric's high-tech non-intrusive ultrasonic flowmeter has been developed for the precise measurement of liquid flow and velocity.
They are quick and easy to install on pipes of all materials and diameters.
This range of industrial flowmeters revolutionizes flow measurement and can be used over a wide range of temperatures and pressures.
Output signals transmit information to your control or monitoring systems.
Increase the quality of your manufacturing through reliable and accurate measurements
Improved productivity due to shorter installation times and no downtime
Reduced maintenance, as the sensors are not in direct contact with the fluids being measured.
The use of transit time technology contributes to the exceptional accuracy of this ultrasonic flowmeter, enabling flow measurement of liquids containing suspended particles or gas bubbles.
Fuji Electric ultrasonic flowmeters use the transit time difference method (different from the Doppler principle) to determine flow rates.
Two transducers working at high frequency are installed outside the pipe.
Ultrasonic waves propagate diagonally across the cross-section from the upstream transducer to the downstream transducer, and then from the downstream transducer to the upstream transducer.
Unlike Doppler ultrasonic flowmeters, which measure the frequency of ultrasonic waves reflected by moving particles, transit time ultrasonic flowmeters operate differently. These flowmeters use the variation in wave propagation time. An ultrasonic wave is sent upstream and downstream of the fluid flow. In one case, the wave is "carried" by the fluid, in the other, it is "braked". It therefore takes a different time to travel from one ultrasonic transducer to the other.
This difference in transit time is proportional to the flow velocity. This method enables fluid flow to be determined with a high degree of accuracy.
Low cost and flexible This measurement and control flow meter instrument reduces the cost of your projects by reducing installation and maintenance costs compared to others flow meter technologies like magnetic flow meters or primary elements flow meters.
Quick and easy to install Installation without pipe drilling requires no modifications, no process downtime and no production stoppages. Your installation is completed in a matter of minutes, without interrupting the process.
Guaranteed safety Since the pipe is not cut, there is no risk of liquid leakage.
Hygienic You can be sure of not contaminating your liquids with debris, as the transducers are mounted outside the pipe.
Maintenance-free The non-contact clamp-on sensors have no moving parts. This product requires no calibration or cleaning.
High durability and robustness High-quality materials are used to ensure a long life for your process equipment.
The sensors and electronic converters have an excellent protection rating.
High measurement accuracy and fast response time The high-performance 32-bit microprocessor electronics allow an accuracy of ±1 % of your flow rates with a response time of 1 sec.
Long-term stability and insensitivity to variations in fluid pressure, temperature and viscosity Continuous calculation of fluid sonic velocity
Simple integration and mounting in your systems Instantaneous flow, volume and thermal energy are displayed. The analog 4-20 mA or pulse output signal of these flowmeters ensures simple data transmission. Digital Modbus communication is also available for your industrial IOT solutions.
Excellent gas bubbles immunity The exclusive ABM anti-bubble technology of the ultrasound beam provides immunity to air gas bubbles for optimal operation at any measuring conditions.
What are the applications of ultrasonic flow meters?
The non-intrusive clamp-on ultrasonic flowmeter offers many advantages. It is used in many industrial processes to monitor and control processes and equipment.
Shipbuilding industries: flow measurement for fuels and hydraulic oils
Other industries: flow of homogeneous liquids that accept the propagation of ultrasonic waves (service water, industrial water, seawater, pure water, irrigation water, oil, etc.).
Our measuring instruments work even on difficult applications.
The signal strength of the transducers adapts automatically to the quality of the pipe and the liquid being measured.
So you can measure with confidence whatever your needs are, even if your piping is corroded.
