Problems with using float level gauges to measure liquid levels
Thread Content
Floats are used to measure the level level; how can one calibrate these floats using the weight-hanging method? How can one calculate the corresponding weights for 0, 25, 50, 75, and 100? Is there any formula for this? Thank you everyone!
There should be two types of interfaces for calculation; using mathematical methods only allows for an approximate estimate, and calibration is also necessary.
Measure the interface level, taking the oil-water interface as an example. When it is completely filled with water, the sinker experiences the greatest buoyant force, while the torsion bar experiences the least torque; at this point, the buoyant force is calculated to determine the range. When fully filled with oil, the sinker experiences the least buoyant force, while the torsion bar experiences the maximum torque; this point is taken as the zero point. Hope this helps!
Calibrating floats using the weight-hanging method is time-consuming, labor-intensive, and requires a lot of calculations; the results are not good either. Moreover, it’s possible to damage good floats during the disassembly and assembly process. Unless internal floats are basically never calibrated in this way. Most of the floating buoys used on-site are calibrated using water through a comparison method; the calibration equipment is simple and easy to operate.
