V. COMPUTATION AND ANALYSIS :
1. Calibration of Water – Meter
Compare the volume collected in the cylinder and the water meter at different
valve opening. Compute for the numerical error and compute the percentage
error.

2. Calibration of Volume Tank
Compare the volume collected in the cylinder and the converted volume from the
known weight of water at given temperature, and compute the numerical error
and percentage error.
Volume = Weighed Mass, kg
Density , kg/m3
3. Calibration of Platform Scale
Compare the readings of the platform scale to the known loads place at different
corners and center, compute the numerical and compute the percentage error.
VI. GRAPH :
1. Plot the valve opening against the percentage error.
2. Plot the water temperature against the percentage error.
3. Plot the platform load against the percentage error.
VII. QUESTIONS:
1. Enumerate the different types of weight, volume, and rates of flow measuring devices
other than mentioned in this experiment. Discuss the operation of each type.

2. Explain the cause of loss of the “sensitiveness” of these measuring devices.
3. Why do you think that it is of great importance in the field of engineering practice
the accuracy of “measurements” in weight or volume.
