The FS1027-DG is a fully calibrated gas flow meter and is targeted for gas flow applications. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio and is ideal for applications requiring low power. The FS1027-DG provides a linear output with flow. It features an Analog, 0 to 4.5V, and Digital I2C output.

FS1027-DG complies with NSF/ANSI 61: Drinking Water Systems Components - Health Effects. It can be safely used for breath and ventilator applications.
