Monitor's line of microwave solids flow monitors are high-quality, industrial-grade instruments capable of providing a signal indicating the flow/no-flow condition of solids and powders in gravity chutes, feeders, and pneumatic pipelines. The Model SFD-2 Solids Flow Detector provides relay outputs that can be set up to indicate changes in the target flow stream (on/off). The Model SFI Solids Flow Indicator provides an analog output which varies with changing conditions of the material flow stream. These non-contact monitors contain no moving parts or probes that can wear out or break off in the material flow, thus ensuring process integrity.

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, 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.
