Description
The FS1027-DL comprise a MEMS flow sensor mounted on a circuit board with an amplification circuit and a flow housing.
The FS1027-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 FS1027-DL outputs a non-linear curve with flow. It features an Analog, 0 to 4.5V, and Digital I2C output.
FS1027-DL complies with NSF/ANSI 61: Drinking Water Systems Components - Health Effects. It can be safely used in water and beverage applications.
Applications
- Water dispensers
- Liquid metering or switch
- Process controls and monitoring

Accuracy depends on factors such as fluid composition, ambient temperature, pressure, humidity, and flow profile. Variations in fluid thermal properties or environmental conditions can alter sensor readings. Calibration is specific to certain fluids, with conversion factors available for others. Proper sensor placement and flow conditioning improve measurement reliability despite turbulent or laminar flow variations.
