Series SF2 Sight Flow Meters

The Series SF2 Sight Flow Meters provide both visual confirmation of fluid flow and electronic output, making them ideal for applications where you need to monitor flow directly while also integrating into automated systems. With solid brass body construction, a durable one-piece composite rotor, and ceramic shaft, they deliver long life even with corrosive fluids and varying flow conditions. Select between SPDT relay output (set point switching) or pulse output proportional to flow rate. These meters suit cooling and lubrication circuits, HVAC, batching systems, and chemical metering. The adjustable set-points allow flexibility for different flow ranges, and the dynamic rotor design reduces jamming and false activation—ensuring dependable operation in real-world industrial environments.
