Flow measurement plays an important role in modern industrial production. Flow measurement methods based on optical fiber systems have become a main research focus.
Applying flow measurement theory and the structural characteristics of optical fiber, flow measurement of paste can be achieved through a combined laser Doppler and optical fiber sensing system based on the principle of optical fiber grating sensors and flow sensors. The system is developed to include light selection, photoelectric detection, a voltage amplifier circuit and a signal filtering circuit.
The system is shown, through a comparative experiment, to be of higher accuracy than the traditional ultrasonic method.
A new method for measuring the paste flow is presented, which is based on the principle of optical fiber Doppler. The method has the advantages of convenient installation, high accuracy and low cost. Experiments show that the method is feasible.
