BFS- Microfluidic Bronkhorst Coriolis Flow Sensor
Flow Sensors tailored for microfluidics
In partnership with Bronkhorst, we have developed a unique coriolis flow sensor suited to microfluidics. It offers various benefits without concession: precision, wide range, straightforward compatibility with all liquids (no calibration needed)…

Designed to suit microfluidic requirements, this flow sensor is based on the Coriolis measuring principle. The performances over a wide range from 1.6µL/min to 3mL/min allow to use a single sensor. It is thus a smart and cost effective alternative to the use of several other sensors.
All our pressure controller systems (OB1, AF1) can be coupled with this flow sensor (BFS). Using our feedback loop (PID), you can monitor and control flow rates in your microfluidic setup while keeping the stability and responsiveness of pressure driven flows.
Enjoy a Smooth & Pulseless Flow
The combination of the BFS Coriolis flow sensor and the extreme pressure stability of Elveflow instruments ensures an enhanced flow control upon first-time use. You can plug our liquid flow sensors anywhere within your microfluidic setup, record the flow rate on your computer and adjust the flow using our pressure controllers.
Superior Coriolis flow sensor
This microfluidic Coriolis flow sensor contains a uniquely shaped, single loop sensor tube, forming part of an oscillating system, providing superior flow measurement performances. When a fluid flows through the tube, Coriolis forces cause a variable phase shift, which is detected by sensors and fed into the integrally mounted pc-board. The resulting output signal is strictly proportional to the real mass flow rate. Coriolis mass flow measurement is fast, accurate, easy to install and inherently bi-directional. Density and temperature of the fluid as secondary outputs.

Mini Cori-Flow operates according to the Coriolis principle. The instrument can be used to simultaneously measure the mass flow, temperature and density. When a fluid flows through a vibrating tube, Coriolis forces are generated which bend or twist the tube. The extremely small tube displacements are detected by optimally positioned sensors and evaluated electronically. Since the measured phase shift of the sensor signals is proportional to the mass flow, the mini CORI-FLOW measures the mass flow directly. One important asset is that this measurement principle is independent of the density, temperature, viscosity, pressure, heat-capacity or conductivity. The tubes always vibrate at their natural frequency, which is a function not only of the tube geometry and the tube material properties but also the mass of the fluid in the vibrating tubes.
