Liquid level measuring unit: sense the level challenge

grabcad

This innovative device measures fluid levels by using a floater connected to an elementary electrical circuit via magnets. The floater (#4) glides on a plastic housing (#3), which responds to water height changes. Inside the housing, there's a basic electric circuit consisting of a small copper rod (#5) that receives power input (any voltage). Another rod (#1) with a higher resistance completes the circuit with the transmitting rod (#2) housed in plastic (#8). The magnetic floater (#9) and metal rollers (#10) ensure the transmitter housing (#8) follows the floater's movement, thus adjusting the circuit's resistance and current flow. This height-dependent current variation is transmitted to a managing unit, such as PLC, through a simple analog module. The device has a sealing mechanism at each end with gaskets squeezed by caps and screws. To alter the stroke length, only the external housing (#3) and transmitting rods (#1 and #5) need modification, which is a straightforward process of cutting to the desired length. All components except electric parts and magnets should be plastic for optimal insulation. French Canadian Alexandre apologizes for any grammatical errors but hopes his explanation is clear.
