For a target flow meter to provide accurate measurements, it is not necessary for the pipe to be completely filled (extra points if it is in close contact with the top!) Encourage discussion)

A target flow meter measures flow rate by utilizing the force exerted by the fluid on the target plate; the strain resistors in the Wheatstone bridge deform due to this force, and the pressure-sensitive bridge converts this into a voltage signal that is proportional to the square of the flow velocity. Flow rate is thus determined from the velocity, and it is obviously related to the cross-sectional area of the pipe. If the fluid does not fill the pipe, the measured flow rate will be inaccurate. At low flow velocities, the fluid may not completely fill the pipeline; therefore, it is important to know whether it is necessary for the fluid to fill the pipe entirely for the target flow meter to give accurate readings. By what percentage above the range is a 2-target flow meter more accurate in measurements? Are low flow rates difficult to measure accurately? Extra points for the sticker on top!
