ABSTRACT:
An electronic flow meter utilizes a light source for directing a beam of light onto a light responsive sensing device, such as a photocell. As solids flow through a hose, they interrupt the light beam, changing the light intensity impinging on the photocell. This change in light intensity alters the output voltage of the photocell in direct proportion to the flow of solids through the hose. The changes in voltage are digitized and transmitted to a computer which utilizes this information in calculations indicating the weight of the solid that has passed through the hose.
