Festo
The Festo part number 564938 is an industrial component utilizing a thermal heat-loss measuring principle to monitor volume and volumetric flow rate from left to right in a unidirectional flow direction. It operates within a flow measuring range of 50 l/min to 5000 l/min for compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen, featuring 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 the RCM compliance mark, c UL us - recognized (OL) status under certificate UL E322346, and CE and UKCA markings per EMC and RoHS directives, it maintains a flow rate accuracy of ±(3% o.m.v. + 0.3% FS) at a nominal temperature of 23 °C within operating and ambient temperatures of 0 °C to 50 °C.
