The present invention relates to a flow rate measurement device and, more specifically, to a flow rate measurement device and a flow rate measurement method, wherein a flow rate is measured by sensing a rotation caused by a flow of a fluid. The present invention provides a flow rate measurement device characterized by comprising: a housing (100) having a fluid inlet port (111) and a discharge port (112) formed to face each other; a rotating portion (200) comprising a rotating shaft (210) arranged perpendicularly to a virtual line (C) connecting the inlet port (111) and the discharge port (112) inside the housing (100), and a blade (220) rotated by a flow of a fluid around the rotating shaft (210); a sensor portion arranged to be spaced apart from the rotating shaft (210) in the radial direction of the rotating shaft (210) so as to sense the number of rotations of the rotating portion (200); and a control portion (330) for measuring the flow rate of the fluid on the basis of the number of rotations of the rotating portion (200) sensed by the sensor portion.

In accordance with an example embodiment, an agricultural work vehicle includes a propulsion system for modifying vehicle speed, a harvesting system for harvesting crop, a perception system having at least one camera with a field of view of a forward zone in front of the vehicle, and a controller. The controller communicates with the propulsion, harvesting, and perception systems, and is configured to receive the perception signal, identify a harvest condition in the forward zone, adjust an operation setting of the propulsion system or harvesting system, and generate a forward-looking perception interface for a display screen. The forward-looking perception interface includes a forward zone area displaying the field of view and a status area displaying at least one harvest condition identified. The status area also displays a time and a sensitivity level associated with the at least one harvest condition identified.

A paddle wheel flow meter includes a base, a paddle wheel, an axis and a magnetic sensor. The base is capable of being embedded in a fluid pipeline, and has two lugs. The paddle wheel is disposed between the two lugs, and includes paddles, two disc wheels, two bearings and at least a magnet, wherein the disc wheels are located at two opposite sides of the paddles, the bearings are respectively disposed in the disc wheels, the magnet is disposed in at least one of the disc wheels. The axis has two ends respectively fixed to the lugs through the bearings. The magnetic sensor is disposed in the base. When a fluid in the fluid pipeline drives the paddle wheel rotating, the magnetic sensor generates an electrical signal by sensing a magnetic field change of the magnet.

There is described a fluid flow measuring and control device for installation within plumbing. The device comprises a main flow channelling system having an inlet and an outlet for connection to the plumbing, and a bypass channelling system in parallel from the main flow channelling system. A flowmeter is provided in the bypass channelling system for measuring the fluid flow in the bypass channelling system and thereby estimating the fluid flow at the inlet or at the outlet of the main flow channelling system. The flowmeter may comprise a wheel and a pair of movement sensors. A valve such as a solenoid valve can be provided as an on/off control for the plumbing. Using a microcontroller, the device can identify which appliance is used and determine consumption, or detect abnormal use or leaks and close the valve and/or notify a user mobile device.
