Single-Piece Flow Detector

Product Details

MODEL: FLOW DETECT 2000

The Flow Detect 2000 emits a low power microwave signal toward the material being monitored. Part of this signal is reflected off the material back to the antenna. This reflected signal combines with the emitted signal to produce a beat frequency, which is the difference in frequency between the two signals.

If the material being monitored is not moving, the reflected signal will be the same frequency as the emitted signal and there will be no beat frequency produced. However, if the material is moving, the reflected signal will be shifted in frequency and a difference or beat frequency will be produced. This shift in frequency is called the Doppler effect. The presence or absence of this beat frequency is sensed by the FD 2000 to detect a flow or no flow condition.

What’s neat about this sensor

Single-piece design eliminates separate controller
Detects solids, granules, pellets, meals & powders
Low power microwave Doppler technology
No contact with the material flow stream
Installs quickly & easily in a 1-1/4” NPT filling
Non-intrusive flush mounting senses flow through non-metallic surfaces
Optional saddle style pipe mount kit available
Ideal replacement for mechanical switches
Hazardous location approvals available
