Cost Optimized CMOSens® Mass Flow Meter

Up to 200 ln/min with an Accuracy of down to 3% of Measured Value for the Entire Flow Range of up to 200 ln/min

Sensirion presents a new generation of cost optimized mass flow meters with patented CMOSens® technology. The main advantage of the CMOSens® EcoLine is its very wide flow range (0-200 ln/min with only one instrument) at an attractive price, especially for OEM applications.

Thanks to the fusion of a thermal sensor element with the readout circuitry on a single semiconductor chip (patented CMOSens® technology), the EcoLine achieves an unusually high dynamic range of up to 1:1’000. This indicates that a single CMOSens® EcoLine meter covers the range of several traditional mass flow meters, which can reduce the system cost significantly.

The EcoLine presents an accuracy of down to 3% of the measured value over the entire range of 1 to 100% of the flow range. The digital output can deliver the measurement data with a speed of 5ms. The rugged chemically inert housing is made of polycarbonate and is resistant to pressure of up to 8 bar (116 psi). This opens up a wide range of application varieties, for instance in process industry, medical applications or in the pharmaceutical industry as well as in chemical engineering. The CMOSens® EcoLine is particularly suitable for OEM applications requiring precision and speed at minimal cost.

Modern technology permits a simple operation following the plug and play principle. The digital readout delivers the calibrated data via an RS-232/SPI interface. The supply voltage can vary between 7 and 18 VDC.
