The fluid moves over an orifice plate with a built-in magnet. A compensating spring allows the mounting in any position. The flow monitors DKM and DKM/A operate without incidence of pressure and viscosity variations.
On both models, a Reed contact is adjustable all along the scale. The contact is Normally Open (closing with overflow).
DKM
It is a blind controller, standard supply with NO contact.
DKM/A
In addition of a NO contact, an analogue display indicates the flow rate (even with quick variations of the fluid speed).
