Product catalog summary
Introduction
The document outlines the features and applications of Monitor Technologies' microwave solids flow monitors, specifically the SFD-2 and SFI models. These devices are designed for detecting the flow or no-flow conditions of solids and powders in industrial settings.

Specifications
The SFD-2 and SFI models are industrial-grade instruments that use microwave technology to detect motion in chutes, feeders, and pipelines. The SFD-2 provides relay outputs for on/off flow detection, while the SFI offers an analog output that varies with material flow conditions. Both models are non-contact, ensuring no interference with material flow, and are approved for hazardous locations.

Features
  • Non-contact sensors that detect flow through non-metallic surfaces.
  • Microwave technology is unaffected by environmental factors like noise, light, and temperature.
  • SFD-2 includes a split-architecture design with a separate power supply and conditioning circuit board.
  • SFI provides a variable analog signal for flow indication.
  • Both models come with a Teflon® or Ryton® process seal for durability.

Applications
The devices are suitable for various industrial applications, including detecting plugs in conveying lines, sensing material bridging in storage vessels, and verifying flow conditions. The SFI model can infer the relative amount of material flow, although it provides only a rough estimate.

Accessories
  • Galvanized half-coupling for mounting the transceiver.
  • Locknut for flexible mounting depth.
  • Saddle coupling for non-welded mounting.
  • Stainless steel adapters for process contact surfaces.

Ordering Information
Details on model numbers, seals, operating voltage, and output options are provided for both SFD-2 and SFI models. Accessories and part numbers are also listed.

Warranty
Monitor Technologies LLC offers a two-year warranty against defects in material and workmanship, with conditions outlined for repair or replacement.

Microwave Solids Flow Monitors Models SFD-2 & SFI-2

The SFD-2 and SFI use low power microwaves to sense motion within the chute or pipeline being monitored. Microwaves are virtually unaffected by ambient noise and light, heat, humidity, pressure, vacuum, high or low temperatures or dust. This provides maximum effectiveness in typical industrial application environments. These advantages over sonic or mechanical flow monitors make microwave technology the best choice for solids flow monitoring.
