BFS Microfluidic Coriolis Mass Flow Sensor

These mass flow sensors are based on the Coriolis principle which allows to measure the flow independently from the type of fluids (gases, water, oil, alcohol...). They are characterized by an excellent precision over a wide range of flow rates from 1.6 µL/min to 500 mL/min. Four versions are available depending on the rage of flow rates and the accuracy you need (0,2% or 2%).

Description

These Coriolis mass flow sensors do not need of periodical calibration and maintenance and this is one of their great advantages! They allow in addition an extremely precise and real-time measure of the fluid flow. 

The sensors can be used with a very wide range of gases and liquids (water, oils, alcohols, mixed solutions/buffers) and the gathered results are independent from the working conditions (pressure, temperature, density, viscosity).

 

 

The device has an USB port to directly connect it to your computer (the USB cable is included) and you do not need of a control station. A dedicated software comes with the device and allow you to easily control the sensor and gather all the measures. The working principle is based on the measurement of the mass flows (positive and negative) and additional parameters such as volume, flow rate, temperature and density are shown as well.

Working Principle 

This Mass Flow Sensor contains a uniquely shaped, single loop sensor tube, forming part of an oscillating system. When a fluid flows through this vibrating tube, the Coriolis forces are generated and they bend or twist the tube. The extremely small tube displacements are detected by optimally positioned sensors and evaluated electronically providing superior flow measurement performances. The fluid cause a variable phase shift and the resulting output signal is strictly proportional to the real mass flow rate. Density and temperature of the fluid are secondary outputs.

Applications

Create your complete microfluidic setup with the BFS Coriolis Mass Flow Sensor and your pressure controller. The device allows you to work with different types of fluids at the same time. A sequential injection of liquid and gas is possible! The sensor together with its software is able to measure with high precision the flow rate in real time and adjust the pressure of the controller accordingly in a high efficient feedback loop.

 

 

The BFS Coriolis Sensor covers a wide range of flow rates and it is perfect for most microfluidic applications! Compared with the MFS Thermal Flow Sensor (click here for more information!), one single BFS Coriolis Sensor can work with the flow rate of 4 different MFS Sensors. This allows you to perform different experiments with the same device while remaining thoroughly precise.
