Sensor Reader fully compatible with Elveflow® Pressure & Flow Sensor

Read simultaneously up to 4 sensors
Compatible with Elveflow Pressure & Flow Sensor
Fast and precise, 10 kHz and a 11 bit resolution,
Real-time control & Feedback loops


An acquisition interface for all your sensors inside your setup

The Sensor Reader is an interface allowing the acquisition of many kinds of analog sensors, including Elveflow pressure sensors and flow sensors. The Sensor Reader can be used to monitor flow rate, pressure, or other physical parameters on any type of flow control instrument (syringe pump, peristaltic pump, perfusion, pressure controller).

Monitoring and feedback control

Connect the Sensor Reader to your computer via USB and monitor measurements of your sensors using the Elveflow® Smart Interface. In addition to monitor, the Elveflow® Smart Interface also offers functions  to control OB1 pressure controlers in response to the measured values on your sensor (using a feedback loop). This allows a real-time control of a pressure or a flow rate anywhere in your microfluidic setup.

Sensor compatibility

The Sensor Reader embeds two independent power supplies which allows the use of a wide variety of sensors simultaneousy, functionning with different voltages for their power supply.

Your needs

Sensor Reader Sketch

You can have the sensors (pressure, flow rate,…) wherever you want in the setup in order to monitor your microfluidic experiment. The Sensor Reader module allows you to control 4 sensors simultaneously via our software and you can use several Sensor Readers if you need. It is an ideal supplement of the OB1 flow controller if you need to control all your experiment parameters.

Sensor Reader Features & Benefits


Benefit in an optimal manner from the performance of Elveflow® Sensors with the Sensor Reader acquisition interface. The open interface Sensor Reader also allows you to use third-party sensors.



Fast and precise

With an acquisition sampling rate of up to 100 Hz and a 11 bit resolution, the Sensor Reader enables you to easily conduct experiments involving monitoring or controlling a physical parameter with analog sensors in real time .

Wide compatibility

Sensor Reader embed two independent power supplies ranging from 5 to 25 V (one for the channels 1-2, one for the channels 3-4). This allows the use of a wide variety of sensors functionning with different voltages for their power supply. Thus, up to four sensors working with 2 different voltages for their power supply can be monitored simultaneously.

> See Elveflow® fully compatible pressure sensor & flow sensor below

Noise reduction

An embeded analog 60 Hz low pass filter function can be activated on each channel independently to reduce sensor noise.


Real time monitoring & FeedBack loops

Our Smart Interface enables you to control your setup after a few minutes of training. Sensor measurements can be  monitored in real time simultaneously with measurements of other Elveflow® apparatuses. Data can be logged and measurements can be used in interaction with other apparatuses to make feedback loops.

Microfluidics flow control software

«Plug & Play Microfluidics» is not just a motto to us. Users will benefit from a control algorithm that ensures an extremely  sensitive and responsive flow rate regulation, while being very simple to operate.


Fitted for microfluidic

Our Sensor Reader achieveS a 11 bits resolution at up to 100 kHz sampling rate and a sub-resolution noise, for accuracy levels on your sensor measurements down to 0.05% of the full scale and response times down to 0.1 ms.

  • Sampling rate up to 10 kHz
  • Resolution : 11 bits (2048 cts)
  • 3 ranges : 0-1 V, 0-5 V, 0-10V
  • Fully compatible with other Elveflow instruments
  • Measurement noise below resolution
  • Noise reduction function with a 3rd order 60 Hz lowpass filter
