Process Engineering Section – Instrumentation and Automation Section – Daily Question – Question dated 2020-09-24: Discussion question: 245. Given that the length of the float is L = 800 mm, and the specific gravity of the liquid to be measured is r = 0.82 grams per square centimeter, use water for calibration. Calculate the heights of water filling required so that the output of the float level gauge is 20%, 40%, 80%, and 100%
When calibrated with water, the maximum height to which the float is submerged is given by: L_water = r_medium / r_water × L = (0.82/1) × 800 = 656 (mm). Dividing 656 mm into 10 equal parts, 10% of this value is 65.6 mm. Thus, the water levels corresponding to an output of 20%, 40%, 80%, and 100% from the float level gauge are 131.2 mm, 262.4 mm, 524.8 mm, and 656 mm respectively.
