Series SF Sight Flow Transmitter

Brand: Dwyer Instruments, LLC
Request Information

Free Shipping on Orders Over $362.88 USD

The Series SF Sight Flow Transmitter is a Series of sight indicators which can display flow or contents of pipelines and provide an Analog 4 to 20 mA signal proportional to the flow rate.

It is available with a 316 SS or clear polycarbonate cover.
Features
  • Integrates tangential turbine technology with hermetically sealed circuitry to provide accurate flow measurement and control in the harshest environments
  • 2-wire loop-powered design transmits a 4 to 20 mA signal proportional to flow rate for remote flow monitoring
  • Clear polycarbonate viewing cover option for visible indication of flow
  • 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 flow in both directions and can be mounted in any orientation
