What sensors can be used to measure changes in the water level in a transparent plastic pipe?
The infusion can be troublesome, and this should be done by the manufacturer who produces the infusion apparatus. The method is to place a styrofoam ball in it, and then solve it by light control. In this way, it is important to fix the reservoir.But this approach has been developed to reduce the work pressure of nurses, especially nurses in intensive care unit.
A magnet can be considered to be wrapped with foam plastic to float on the surface of the water. It is placed inside the transparent plastic tube, and a magnetic reed switch is used outside the plastic tube to induce the magnetic field switch.
The patient does not need transfusion to quantitatively measure the water level, only need to point measurement, so we can use the photoelectric sensor (a transmitting tube and a receiving tube), because of the refraction of water and air rate is not the same, and the infusion tube is cylindrical, equal to a lens, so that can detect changes in water and water, to remind the nurse.
