Series SF Sight Flow Transmitter
Brand: Dwyer Instruments, LLCThe 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
