Festo
The Festo 565400 is a thermal industrial component that measures volume and volumetric flow rate for unidirectional flow from P1 to P2 using the heat loss measurement principle. It operates within a flow measuring range of 2 l/min to 200 l/min, an operating pressure of 0 MPa to 1 MPa (0 bar to 10 bar, 0 psi to 145 psi), and a medium and ambient temperature range of 0 °C to 50 °C with compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen as the operating medium. Certified with the RCM compliance mark, c UL us Recognized (OL) under UL E322346, and compliant with EU and UKCA directives for EMC and RoHS, this RoHS-compliant unit delivers a flow rate accuracy of ± (3% o.m.v. + 0.3% FS) at a nominal temperature of 23 °C.
