Coriolis Based Flow Sensing
Specifically designed to suit microfluidic requirements, this flow rate sensor is based on the Coriolis principle. Its features make it the best and smartest solution for microfluidics applications:
- Extremely wide flow rate range
- High accuracy
- Direct mass flow measurement, independent of fluid properties
- Non-invasive measurement
- Additional density and temperature outputs
- Bi-directional measurement
- Fast response
Flow Rate Control
You can achieve flow control of your experiment by combining the Coriolis Flow Sensor with our pressure controller systems (OB1, COBALT). The Elveflow ESI software automatically adjusts the pressure to reach the required flow rate. Researchers who want to monitor the flow rate from their third party fluid driver can plug the flow sensor directly onto the computer.
User Friendly and Cost Effective
- Cost-effective solution: one sensor’s operating range covers the ranges of several standard microfluidic sensors.
- No calibration required
- Stand alone sensor: plug the sensor directly to your computer to measure the flow rate.
- Excellent repeatability and long-term stability
- Excellent accuracy: down to 0.2 % of measured value accuracy
- Easy to install and use
- Low risk of gas bubble inclusion
How does a Coriolis flow meter work?
A microfluidic Coriolis flow sensor contains a U-shaped loop which constantly vibrates. When a fluid flows through this vibrating loop, Coriolis forces are generated and bend or twist the tube. The extremely small tube displacements are detected by sensors and fed to the electronic board. Since the measured phase shift is proportional to the mass flow, the Coriolis flow rate sensor measures the mass flow directly. This measurement principle is very accurate, fast and, more importantly, independent of the properties of the fluid (density, temperature, viscosity, pressure, heat-capacity or conductivity).

FAQ
Q: Do I need an OB1 Pressure controller or a Sensor Reader to interface with my BFS?
A: No, the Bronkhorst flow sensor (BFS) is directly connected to your PC by USB. Make sure you have a sufficient number of USB ports available or use an USB hub.
Q: Is it possible to get a calibration certificate?
A: Absolutely, the 505829 (BFS1+), 505830 (BFS2) and the 505831 (BFS3), are individually calibrated by Bronkhorst before shipping. A calibration certificate is provided with each of these sensors.
