Microsense Flow Switch

Hycontrol’s Microsense flow/no-flow detector offers a simple and safe solution to a variety of production applications. When applied to solids, powder or particulate products, the single-piece, non-contact unit can be used to alert operators to disrupted flow where continued supply is required (perhaps caused by a blockage or loss of supply), or, conversely, it can be used to confirm flow has stopped completely before a new material is introduced into the flow stream, eliminating the risk of cross-contamination.

The flow switch uses a microwave Doppler effect and is non-invasive. During operation, the sensing head transmits a continuous low-power microwave beam onto the path of the flowing product. The microwaves are partially reflected by any product that is present, and these reflections are then analysed as to whether the product particles are moving or stationary objects.

The highly penetrative microwave beam emitted by the Microsense unit passes through any build-up on the transmitter face and will even detect through pipes of non-conducting materials such as plastic and ceramics. The switch is best suited for the detection of materials such as dry solids, granules, flakes, and powders. Microsense is sensitive enough to register very low levels of flow to ensure operators are fully aware of their flow or no-flow status. This helps operators to ensure they are achieving relevant hygiene standards by ensuring there are no contaminants from other material flows present.

Typical applications include grain, flour, cement, ore, stone coal and animal feed mills. Flow can be detected in pipelines, chutes, transfer bins, distributors, feeders, conveyor belts, bucket elevators or free air. For extra security, this detector can be combined with a microwave blocked chute monitoring system to provide both flow or no-flow output and blocked or clear chute indication, providing operators with maximum plant protection.
