Single-Piece Flow Detector: Flow Detect 2000

The single-piece Flow Detect 2000 flow detector from BinMaster is a flow/no flow detector that, in contrast to the two-piece flow detector, accommodates the remote sensor as well as the control console in a single NEMA 4X enclosure.

The Flow Detect 2000 helps avoid cross-contamination by guaranteeing flow has been halted before new material is added into the flow stream. It can help prevent possibly hazardous and expensive USDA, FSMA, or FDA compliance problems at facilities manufacturing food for animal or human consumption. It is suitable for detecting flow conditions of powders and solids in conveyor belts, feeders, pipelines, gravity chutes, or bucket elevators.

Optional North American Class II, Division 1 Groups E, F, and G and ATEX Zone 21 hazardous location approvals can be requested from BinMaster.

Applications

  • Installed in pipelines, distributors, conveyor belts, feeders, gravity chutes, or bucket elevators
  • Flow/no flow detection to stop cross-contamination of ingredients
  • As a preventive control for USDA, FSMA, or FDA compliance
  • Used for pellets, solids, meals, granules, and powdered materials
  • In hazardous sites where there is the risk of combustible dust
  • Suitable for a majority of industries, including grain, milling, food, feed, cement, power, plastics, and mining

Features

  • Easy to install
  • The power and output connections, sensing element, and user adjustment controls are contained in a single NEMA 4X enclosure
  • Uses Doppler technology (microwave) to offer dependable motion detection
  • Non-contact operation removes equipment wear and flow stream interruption
  • Capable of passing through non-metallic materials
  • Non-intrusive flush mounting senses through non-metallic surfaces
  • LED lights for flow/no flow status
  • North American Class II, Division 1 Groups E, F, & G and ATEX Zone 21 hazardous location approvals (optional)
