FS10i

The FS10i is designed for a range of applications, from compressed air to lube oil to HVAC ducts. It is fully programmable using a PC / laptop & suitable for pipe sizes from 1/4″ to 12″.

The sensor has a 1/4″ or 1/2″ compression fitting which means it can be withdrawn “live” through a ball valve and it is the only product in its class to carry a SIL 2 compliance rating with a 90% Safe Failure Fraction (SFF).

The instrument features a ten (10) LED array to indicate actual flow range and, when trip point is reached, the LED will begin to flash to provide an immediate visual indication to the user. To ensure best performance and installation ease, the FS10i is available in a choice of three flow element lengths (insertion depth) and process connections: a 2 inch [50 mm] length with a 1/4″ NPT (M); or a 6 inch [150 mm] length, variable depth, with 1/2 ″ NPT (M) compression fitting with either a Teflon or metal ferrule.
