ELVEFLOW Flow Sensor 4 Digital Buy ELVEFLOW products from MSE Supplies at the best value. Product Description Microfluidic flow sensor Working range from 0 to 1000 µL/min with aqueous solutions Compatible with OB1 MKIII+ and Sensor Reader v2 only Elveflow® Smart Interface software included. /! Without 1/4-28" fittings /! Elveflow’s Microfluidic Flow Rate Sensor uses thermal time-of-flight technology to flow rates in micro-size channels. Its features make it a robust, reliable and affordable solution for microfluidic applications: 5 sensors covering water flow rates from 0.07 to 5000 µL/min 5% accuracy on most of the operating range Fully compatible with other instruments from the Elveflow range (MSR Sensor reader and Flow Controllers – OB1, Cobalt -) Non-invasive measurements High chemical compatibility: wetted parts made of PEEK and glass Low dead volume down to 1 μL Bi-directional flow rate measurement (positive & negative) Flow Rate Control You can achieve flow control of your experiment by combining any Microfluidic Flow Sensor with our pressure controller systems (OB1 MK4, Cobalt). The Elveflow ESI software automatically adjusts the pressure to reach the required flow rate. Researchers who want to monitor the flow rate of a third party instrument like a syringe pump can plug the flow sensor to our Microfluidic Sensor Reader (MSR). Smooth, Pulseless Flow All our flow controller systems (OB1 MK4, Cobalt) can be coupled with the Microfluidic Flow Rate Sensor. Using the feedback loop control of our ESI software, you can accurately monitor and control flow rates in your microfluidic setup in a stable, pulseless and responsive fashion. Directly input the flow rate into the software to reach the requested value. The microfluidic flow sensors can be plugged anywhere inline in your microfluidic setup. Which Flow Sensor to Choose? Elveflow offers 5 different flow rate sensors (+1 Coriolis Bronkhorst Flow Sensor) that are each accurate and precise in a given range. Use our explanatory range and accuracy chart in order to choose the most fitting Flow Sensor for your application. Note: Please note that the range may change depending on fluid properties (thermal conductivity, density and thermal capacity ,…etc.). Sensor Reading Module The Sensor Reader is a device specifically designed to be used with all of Elveflow’s sensors. The reader allows to use Elveflow Sensors with any third party instrument used to drive liquid (syringe pump, peristaltic pump, perfusion, pressure controller). Thermal Time-of-flight or Coriolis Based Sensor? Elveflow offers two types of flow rate sensors: one based on the thermal conductivity technology (Microfluidic Flow Sensor) and one based on the Coriolis principle (Bronkhorst Flow Sensor). Both sensors have pros and cons that have been summarized in the table below. This table helps you choose your sensors depending on your application and your budget.
