Product 3D Image Get couponsIn-line mounted, mechanical flow switches for liquid or gaseous media. Robust plastic, aluminium or stainless steel housing available. Extremely low pressure loss, good repeatability, dirt immunity, complete isolation of the mechanical and electronic parts for economical use with small flow rates. With a switching scale, the user does not have to set it in the field, LED indication of the switching status and a magnetic bead on the panel indicating the flow rate.
Pneumatic liquid dual purpose, industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning.
