The FS1023-DL comprise a MEMS flow sensor mounted on a circuit board with an amplification circuit and a flow housing. The FS1023-DL is targeted for liquid applications. The sensor utilizes thermopile sensing, which provides an excellent signal-to-noise ratio and is ideal for applications requiring low power. It is highly sensitive at low flow rates with a very fast response time.The FS1023-DL outputs a non-linear curve with flow. It features an Analog, 0 to 4.5V, and Digital I2C output. FS1023-DL complies with NSF/ANSI 61: Drinking Water Systems Components - Health Effects. It can be safely used in water and beverage applications.
