The Series SF Sight Flow Transmitter is a Series of sight indicators which can
display ow or contents of pipelines and provide an analog 4-20 mA signal proportional
to the ow rate. It is available with a 316 SS or clear polycarbonate cover.
FEATURES/BENEFITS
• Integrates tangential turbine technology with hermetically sealed circuitry to provide
accurate ow measurement and control in the harshest environments
• 2-wire loop-powered design transmits a 4-20 mA signal proportional to ow rate for
remote ow monitoring
• Clear polycarbonate viewing cover option for visible indication of ow
• 316 SS cover offers added protection with pressure limit up to 500 psig (34 bar)
• LED power indication, adjustable zero and span, polarity protection and over current
limiting
• Accurately measures ow in both directions and can be mounted in any orientation
APPLICATIONS
• Cooling and lubrication circuits
• HVAC systems
