Festo
The Festo part number 573351 is an industrial component utilizing a thermal heat loss measuring principle to monitor volume and volumetric flow rate in a unidirectional, left-to-right flow direction. Operating within a flow measuring range of 150 l/min to 15000 l/min, it handles compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen at an operating pressure up to 1.6 MPa (16 bar, 232 psi) and an overload pressure of 2 MPa (20 bar, 290 psi). Certified with RCM compliance, c UL us recognition (UL E322346), CE marking per EU EMC and RoHS directives, and UKCA marking, the unit delivers a flow rate accuracy of ±(3% o.m.v. + 0.3% FS) across a medium and ambient temperature range of 0 °C to 50 °C.
