Festo
The Festo part number 565398 is an industrial thermal measuring principle component utilizing a heat loss method to measure volume and volumetric flow rate for unidirectional P1 to P2 flow directions. This unit features a flow measuring range from 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 operates with compressed air as per ISO 8573-1:2010 [7:4:4] or nitrogen within medium and ambient temperatures of 0 °C to 50 °C. It maintains 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 a temperature coefficient margin of typ. 0.1 %FS/K 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 RoHS-compliant component is ready for procurement. Please submit the exact part number, quantity, and application requirements for a formal quote.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
