FLOCON
|
Transport of particles in pipes by air in a pipe is usual in all fields of industry. But how to determine the amount of materials passing through? |
The dimension of this result is like a multiplication of density and speed. There is a very interesting physical effect described in books: The Doppler effect. Everybody knows it and can hear it, e.g. when a horn is bowing and passing by. The tone immediately changes, when arrives. The tone is different, when the horn is coming and leaving. This effect is used by the police to measure the speed of cars. The FLOCON uses the same priciple and the same method like car radar. |
It is not using sound waves like described the Doppler effect with a horn. It is using micro waves with 24 GHz frequency. The other name is RADAR. |
Because micro waves are not able to pass through metal, it needs
a hole in the pipe, diameter about 20mm or about 0.8 inch |
The standard output of the evaluation unit is a
4-20mA analogue signal. But, it has digital outputs for process computers or it can be equipped with a Com interface in the front, to use a laptop to overtake data or even to
calibrate it. All functions are available also via laptop. |
