Microwave Type Flow Sensor KFD-1

Even one pellet is not overlooked! Highly sensitive and stable by 24 GHz power!

Features

Even one pellet is not overlooked by our proprietary circuit
Indirect detection through glass, synthetic resin etc. is available
Not affected by dirt, scale etc. on the detection surface
Sensitivity adjustment enables both small or large flow detection

Operating Principles

Once a microwave emitted from the sensor reaches powder or granule flowing in the pipe, the reflected microwave converts and amplifies the frequency deviation by Doppler effect, and outputs contact.
