A method for detecting a flow velocity of a high-temperature molten fluid can include: collecting a video stream of a high-temperature high-velocity molten fluid, decomposing the video stream into a frame image sequence sorted by time, and extracting a molten fluid Region Of Interest (ROI) from the frame image sequence, extracting a molten fluid outline of the molten fluid ROI, and extracting a characteristic block of the molten fluid outline, and obtaining the flow velocity of the molten fluid based on the characteristic block. A flow velocity detection accuracy can be improved for a molten fluid with a high temperature, a high velocity and a high glossiness.

A system and method includes a seed roll of a saw type gin stand which can easily be inspected in an efficient and safe manner within the normal course of operation. The monitoring of the seed roll is desirable for prediction of irregularities that could significantly hamper the production of a ginning facility. This monitoring can take place by manual inspection with the eye or touch of the operator. In addition, this feature will facilitate the opportunity to introduce a new automatic process by which the control system can monitor the seed roll in order to improve overall productivity of the gin stand.

An x-ray mass flow rate sensor uses a low density polymer pipe, an x-ray source, and an x-ray detector. The polymer pipe has a low density (less than 2.8 SG) and a high pressure rating (greater than 5 ksi). By using a low density polymer pipe, the sensor is able to use an x-ray source that does not require a linear accelerator and is less than or equal to 450 kV. The x-ray source and the x-ray detector are mounted on opposite sides of the polymer pipe to form a detection area that passes through the polymer pipe. A real-time calibration of the sensor is performed by detecting gray level values in a calibration region of the detection area for two reference materials placed in the detection area. The sensor may additionally include a mechanical flow rate sensor with a plurality of pistons with springs of varying spring constants.

A method of fluid flow measurement includes a emitting a light beam into a pipe through which a fluid flows, the light beam illuminating the fluid flowing in the pipe, using a light detector array to detect light caused by scattering of the beam with particles found in the fluid, the light beam being outside a field of view of the light detector array, dividing the field of view of the light detector array into layers, and determining an instantaneous flow velocity in each of the layers as a function of signals transmitted from the light detector array in each of the layers.
