“Setting The Standard For Supplier Excellence” Microwave Solids Flow Monitors M o d e l s S F D - 2 & SFI M Best Value In Solids Flow Detection Superior Application Versatility Excellent Sensitivity Indicate Flow/No-Flow In Chutes, Feeders and Pipelines On/Off Flow Detector (SFD-2) Analog Output Indicator (SFI) Hazardous Location Approval

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.

TRANSCEIVER (SENSOR) M Powder coated Nema 4 cast aluminum construction Monitor’s Solids Flow Detector and Indicator can be used in a variety of applications to detect flow/no-flow conditions of powders and bulk solid materials. The selection of either SFD2 Solids Flow Detector or the SFI Solids Flow Indicator is based upon the type of output required (relay or analog). M Approved for Class II hazardous areas M Meets applicable FCC regulations M Screw-on/off cover Typical applications include: M Detection of a partial or full plug in a conveying line M Teflon ® process seal is standard M...

STAINLESS STEEL ADAPTERS Four different mounting adapters can be used to provide a stainless steel process contacting surface. The adapter can be of either 1-1/2" NPT or Tri-Clamp ® food grade construction. GALVANIZED HALF-COUPLING Monitor provides a galvanized half-coupling which can be welded to the chute or pipe for mounting the transceiver. Half Coupling: P/N 17-3111 LOCKNUT The optional locknut provides flexibility in the depth of the mounting of the transceiver to ensure that the process seal is flush with the inside of the conduit in which the target material flows. Lock Nut: P/N...
