Festo
8058464
Flow sensor SFAH-0.5U-Q4S-PNLK-PNVBA-M8
The Festo 8058464 industrial component is a thermal, unidirectional flow measuring device utilizing heat transfer to monitor mass flow and volumetric flow rates from 0.01 l/min to 0.5 l/min for argon, nitrogen, and compressed air complying with ISO 8573-1:2010 [6:4:4]. It operates across a pressure range of -0.9 bar to 10 bar and ambient and medium temperatures from 0 °C to 50 °C, achieving a flow rate accuracy of ± (2% o.m.v. + 1% FS) at a nominal temperature of 23 °C. The unit carries RCM and c UL us - Listed (OL) certifications alongside CE and UKCA markings per EU and UK EMC and RoHS directives.

Request a QuoteWhy no listed price?
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.
