.jpg) | Series SFI - ANDERSON-MIDWEST Sight Flow Indicators Inexpensive Protection for Expensive Equipment and Systems W.E. Anderson - Midwest Sight Flow Indicators are manufactured of quality materials and safety tested to assure long, dependable service at economical prices. Available in window viewing style in the 100 and 300 Series and tube viewing style in the 400 and 700 Series with connection choices of female NPT, BSPP, or BSPT threaded and flanged. Series 700 has impeller and internal wipers for cleaning sight tube, which is perfect for fluids with suspended solids. Just rotate the glass tube and restore full 360° visibility without disrupting the flow.   | ||||||||
.jpg) | Series SF2 - Sight Flow Meters SPDT or Pulsed Output, Visual Flow Confirmation, Brass Body Series SF2 Sight Flow Meters combine visual confirmation of flow with a relay or pulse output. The brass, unibody construction, one piece composite rotor, and ceramic shaft delivers durability with broader chemical, temperature, and pressure capabilities. For specific flow setpoint switching, select SF2-1 meters with a SPDT relay output. Setpoints are fully adjustable over the specified flow range. The dynamic operation of the rotor guards against jamming and false actuation. For flow rate monitoring or metering applications, select SF2-2 meters with a pulse output proportional to the rate of flow. The 4.5 to 24 VDC pulse output is compatible with most digital logic families. | ||||||||
.jpg) | Series SFI-800 - Sight Flow Indicator/Transmitter Low Cost, Optional Output for Flow Rate and Totalization, New UV Stabilized Polycarbonate Model The Series SFI-800 Sight Flow Indicator is a low cost, durable rotor style flow indicator with optional output sensor. Constructed of clear Polysulfone, enabling 360° viewing of the rotor, the SFI-800 has excellent pressure ratings, temperature ratings, and chemical compatibility. The Series SFI-801 Sight Flow Indicator is similar to the SFI-800 except it is made of UV stabilized materials. It can be used in outdoor applications whre indication of flow or control is needed. The materials are not FDA approved. The SFI-801 also features an easily viewed bright red impeller. | ||||||||
.jpg) | Series SFI-100T - Sight Flow Indicator/Transmitter Output for Flow Rate and Totalization The SFI-100T is a low cost and durable flow transmitter that combines our popular 100 Series Sight Flow Indicator with our A-711T output sensor. The SFI-100T sight flow indicator is constructed of a robust, solid brass body and a tempered glass window. A bright red impeller is featured for great visual indication of flow through the window. The front window can be easily unscrewed to clean out the sight flow indicator. Ideal for outdoor applications, the flow transmitter is weatherproof and unaffected by UV light. The A-711T output sensor has a VDC output with pulsing for flow totalization and a proportional frequency change for flow rate. For added versatility there are two output choices of 5 VDC or a VDC equal to the input power supplied. The output is compatible with digital rate meters/totalizers and other electronic systems. | ||||||||
