Flow meters for single-use systems
Alflow offers a wide range of ultrasonic non-invasive flow meters and clamp-on transducers for liquid-carrying hose systems in the medical, pharmaceutical and bioprocess industries.
The flow meters are used to monitor flow rates in bioprocess engineering. The function is based on the ultrasonic transit time method and is non-invasive, meaning there is no direct contact with the medium, making it particularly suitable for processes with strict hygienic requirements. See the range of flow meters for single-use systems from leading manufacturers on this page.
What are flow meters for single-use systems?
The flow meter system consists of a flow sensor, a Clamp-On transducer and an electronic evaluation system, the flow meter. In combination with the flow meter, the Clamp-On transducer ensures reliable monitoring of the volume flow rate in laboratories or industrial applications.
Innovative design combined with an established and reliable technology for real-time volumetric flow monitoring provides a truly compact and space-saving solution. Our flow meters can be used with all sizes of our non-invasive clamp-on transducers, and it is also possible to change sensors and/or sensor sizes.
As mentioned, the operating principle is based on the ultrasonic transit time method and is thus non-invasive and determines the transit time difference of ultrasonic signals through a measuring section and is used to evaluate volumetric flow rates.
A typical transit time flow measurement system incorporates two piezo ceramic plates that act as both ultrasonic transmitter and receiver. The flow measurement is performed by alternately sending and receiving an ultrasonic pulse between the two transducers and by measuring the transit time difference it takes the ultrasonic pulse to travel between them.
For higher accuracy, our Clamp-On transducers incorporate two pairs of ultrasonic transducers. They consist of four piezo ceramic plates and are arranged in an X configuration around the tube containing the measured flow.
When sending ultrasonic audio signals through the measurement section, the transit time difference depends on the flow direction of the medium. If the ultrasonic audio signals are sent with the flow direction, the downstream signal needs less time and if the ultrasonic audio signals are sent against the flow direction, the upstream signal needs more time.
The evaluation of the received ultrasonic signals is based on the upstream and downstream measurement sections and the transit time difference is measured for each pulse. The difference between the upstream and downstream targets is proportional to the volumetric flow rate.
Find the right flowmeters for your single-use application
Our flow meters are made of materials that ensure extremely high cleanliness and thereby the best conditions for your product. They are available in different variants with standard interfaces that allow optimal integration into automated environments. They are available with 1, 2, 4 and 5-8 channels/outputs and in an analogue version with 1-2 channels/outputs. The flow meters can be used in a wide range of applications in the medical, pharmaceutical and bioprocess industries, among others:
- Flow measurement on disposable equipment
- Flow measurement on flexible pipes
- Adding media to bioreactors
- Chromatographies, filtration, fillings, process evaluation, scale-up, research, etc.
- Flow monitoring during chromatography or filtration at lab scale
- Control of the upstream feed
- Fillings
- Evaluate and scale up processes
- Checking process equipment such as pumps or valves
- With more
The use of sterile single-use components saves time and reduces the risk of cross-contamination while increasing productivity between batches. Manufactured with quality in mind, the systems can be quickly installed and operational in a fraction of the time needed to install traditional stainless steel systems used for pharmaceutical and biotech filling.
