PRODUCT DESCRIPTION

Product Description

SF5019 series of gas flow meters are specially designed for the industry gas measurement with high performance and accurancy, LCD interface, RS485 network communication and easy networking remote monitoring. SF5019 series consist of flow sensing unit which based on MEMS , high accurancy digital processing system and MCU.

SF5019 series adopt 24bit△-ΣA/D converter and self-calibrated logic circuit and MCU which ensure real time data collection for sensing signal and accurate flow output, accurate flow signal acquisition and compensation algorithm processing internally, no need external calibration compensation. Friendly digital communication output style and convience for customer to proceed communication data information

with circuit system integration of various anti- electromagnetic interference design make SF5019 widely applied to the various industry environments.
