What is the primary difference between the 'FLK-' flow meters and the 'FL-' flow meters? I see the inlet pressure difference but is there some reason for choosing, for example, the FL-2011 (0.1-1 LPM) over the FLK-2211 (also 0.1-1 LPM)?

Asked by: KenW
Thank you for your inquiry! These meters are very similar and are interchangeable in many applications. The meters differ slightly in wetted materials and pressure which are the only major differences.
