Festo
The Festo part number 565388 is a thermal industrial component that measures volume and volumetric flow rate using a heat loss method in a unidirectional P1 to P2 flow direction. It operates with compressed air as per ISO 8573-1:2010 [6:4:4] or nitrogen across a flow measuring range from 0.1 l/min to 10 l/min, supporting an operating pressure range 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. The unit features RoHS-compliant materials, RCM compliance, cULus recognition via UL E322346, and CE and UKCA markings per EMC and RoHS directives, delivering a flow rate accuracy of ± (3% o.m.v. + 0.3% FS). Please submit the exact part number, quantity, and application requirements to receive a formal quotation.
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.
For a faster response, include quantity, condition, and delivery destination.
