PLF2105 - LIQUID FLOW SENSOR

Download the PLF2105 datasheet PDF. This datasheet also covers the PLF2000 variant, as both devices belong to the same liquid flow sensor family and are provided as variant models within a single manufacturer datasheet.

Description

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.

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 the surface cavity or fragile membrane used in competing technologies. The sensor die, with its silicon carbide protective film, is capable of direct contact with l.

PLF2000 Series LIQUID FLOW SENSOR FOR WATER METERING 131 E. Brokaw Road | San Jose CA 95112 | +1 (408) 392-0989 | info@posifatech.com | www.posifatech.com DESCRIPTION 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.
