Festo
The Festo part number 573357 is a thermal industrial component that measures volume and volumetric flow rate for compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen moving unidirectionally from left to right. Utilizing the heat loss measurement principle, this device operates across a flow measuring range from 150 l/min to 15000 l/min with an operating pressure up to 1.6 MPa (16 bar / 232 psi) and an overload pressure of 2 MPa (20 bar / 290 psi). It features a flow rate accuracy of ±(3% o.m.v. + 0.3% FS), a zero point repetition accuracy of 0.2 %FS, a repetition accuracy margin of 0.8 %FS, and operates within a medium and ambient temperature range of 0 °C to 50 °C at a nominal temperature of 23 °C. Certified with RCM compliance, c UL us recognition (UL E322346), CE marking per EU EMC and RoHS directives, and corresponding UKCA markings, the unit is fully RoHS compliant.
