Posifa designed the PLF2000 series of liquid flow sensors to replace mechanical turbine flow sensors. With a MEMS thermal flow die at its core, PLF2000 is far more accurate and repeatable, even when flow is pulsatile and provides a linear digital output. Because it has no moving parts, PLF2000 does not get stuck nor suffer mechanical breakdown. Cleaning does not require disassembly. Also, because it does not introduce an obstruction (i.e. turbine) in the flow path, it presents minimal flow resistance, making it possible to circulate liquid via gravity, a boiler, or a low-power pump. 
PLF2000 features Posifa’s third-generation thermal flow die, benefiting from the latest innovations in microfabrication. The sensor die uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow, delivering excellent signal-to-noise, and repeatability. The “solid state” thermal isolation structure eliminates the need for surface cavity or fragile membrane used in competing technologies. The sensor die, with its silicon carbide protective film, is capable of direct contact with liquid, allowing the highest level of sensitivity and minimizing the cost of packaging.
PLF2000 complies with NSF/ANSI 61: Drinking Water System Components – Health Effects and can be used safely in water and beverage appliaces.PLF2000 provides both analog (voltage) and digital I2C output.
