The FS10i is a compact, economical solution to natural gas flow metering. Utilizing application proven thermal mass flow technology, the FS10i provides a highly accurate and repeatable linearized 4-20 mA output of flow rate. It was the first thermal flow meter, and is currently the only one, to comply with SIL 2. Additionally, for applications benefiting from a high or low flow alarm point, the FS10i includes a user programmable 1A SPDT relay output.
