Series SF2 Sight Flow Meters

SPDT or Pulse Output, Visual Flow Confirmation, Brass Body

The SERIES SF2 Sight Flow Transmitters combine visual confirmation of flow with a relay or pulse output. The SF2-1 offers a SPDT relay output and the SF2-2 offers a pulse output proportional to the rate of flow. The 4.5 to 24 VDC pulse output is compatible with most digital logic families.
