Operating Instructions, Mounting & Installation

Flow monitors, mechanical, with paddle, with switching output Dimensional drawing
SW – 3E SW – 4E
Incl. attached Tee Fitting according to DIN 2950
Mechanical paddle flow monitor RHEASREG®
SW with switching output, in an impact-resistant plastic housing, with stainless-steel paddle, for flow monitoring of liquid and gaseous, non- aggressive media in pipes, hydraulic systems of ¾” through ½” to 8” diameter. The flow sensor is used as a flow controller or low water alarm, e. g. for pumps in oil and cooling circuits, cooling systems, evaporators, compressors and heat exchangers, with brass or stainless-steel bodies.
