Product Overview
The HORIBA STEC LF-F40M-A-EVD1 is a precision liquid flow controller engineered for accurate, repeatable delivery of process liquids in advanced industrial and semiconductor-grade fluid handling systems. As a member of the HORIBA STEC LF series, this device combines a high-resolution flow sensing element with an integrated control valve to provide closed-loop regulation of liquid flow rates. Unlike a pump, the LF-F40M-A-EVD1 does not generate flow; it precisely meters and modulates the flow of liquid supplied from an external pressurized source. Its role in industrial systems is to maintain stable, calibrated flow setpoints for processes requiring exact liquid dosing, mixing, or delivery, making it a critical component in high-purity and high-accuracy fluid circuits.
