Images 1 DFM 20-2M Flow meter Variants Manuals Benefits integrated ball valve for adjustment and shutting offdirect indication of the flow rate in l/minadjustment without diagram, table or measuring instrumentavailable with many connection types Application For hydraulic balancing and flow monitoring in heating/cooling systems, air conditioning systems, solar systems and geothermal systems. DFM allows for fast hydraulic balancing of the system or of system components without diagrams, tables or measuring instruments. Suitable for heating and cooling water as well as water mixtures with standard corrosion protection and antifreeze agents. Description Compact flow meter with scale and ball valve for shutting off and adjustment. The flow meter can be installed in pipes in a horizontal, tilted or vertical position. Adjustments are made by means of a screwdriver via the adjustment screw. The reading mark corresponds to the lower edge of the rotameter/float. Systems with correct hydraulic balancing provide for optimum energy distribution and cost-efficient operation.
