The single-piece flow detector is a flow/no flow detector that, unlike the two-piece flow detector, houses both the remote sensor and control console in a single NEMA 4X enclosure. An important benefit of the Flow Detect 2000 is that it helps prevent cross contamination by ensuring flow has stopped before a new material is introduced into the flow stream. It can help prevent potentially dangerous and expensive FSMA, USDA, or FDA compliance issues at a facilities producing food for human or animal consumption. It is ideal for detecting flow conditions of solids and powders in gravity chutes, feeders, pipelines, conveyor belts, or bucket elevators. It is suitable for most industries, including the feed, grain, milling, food, cement, mining, power and plastics industries. Optional North American Class II, Division 1 Groups E, F, & G and ATEX Zone 21 hazardous location approvals are available.
The Flow Detect 2000 uses microwave Doppler technology for highly sensitive motion detection, which is able to pass through non-metallic materials. This provides the device with the ability to 'see through' a plastic pipe, a glass process seal or the wall of a wooden chute to detect the material inside the encasement. It includes a switchable filter which reduces the effect of vibration and ensures the detection of moderate and fast-flowing materials. A single analog relay output communicates flow or no flow status to a PLC and has the option of using both normally open (NO) and normally closed (NC) contacts. LED indicator lights inform the end user of the device's status.
